JIC Male 74° Cone Fitting for R5 Hose: 16718-R5 Series

Why This R5 Hose Fitting Passes the Compliance Gate

A JIC male 74° cone fitting terminates a textile-reinforced R5 hose with a male JIC 37° flare end, ready to connect to any female JIC cone seat or swivel nut in the circuit. The 16718-R5 series from HENGHUA is a one-piece crimp fitting built to SAE J514 (ISO 8434-2), with a stem geometry engineered for R5-family hose, covering 10 sizes from -04 to -24 with UNF threads from 7/16″-20 to 1-7/8″-12. Every unit is cold-forged from carbon steel, heat-treated, plated, and 100% pressure tested before shipment. For OEM buyers this fitting is a compliance gate; for maintenance teams it is the fitting that keeps R5 hose circuits on one reliable termination.

• SAE J514 (ISO 8434-2) JIC male end: UNF thread with a 74° included external cone (37° flare), sealing metal-to-metal into a female cone seat or swivel nut, with no O-ring and no thread sealant required.
• R5-engineered stem: the stem and ferrule geometry is matched to the softer cover and textile reinforcement of R5-family hose, so the crimp grips without crushing the carcass.
• OEM gate check: full dimensional and material conformance per SAE J514, with material test reports (MTR) available for every batch.

Core Advantages

1. Correct grip on textile hose: the R5 stem profile distributes the ferrule load across the textile carcass, which a standard wire-hose fitting cannot do reliably.
2. JIC end rated up to 34.5 MPa (5,000 psi): per SAE J514 / ISO 8434-2, with every fitting hydrostatically tested before shipment.
3. -40°C to +120°C operating range: matches the continuous rating of R5-family hose and the wider circuit.
4. 96 to 1000 h salt spray options: trivalent zinc (96 h), zinc-nickel (720 h), or Dacromet (1000 h), matched to your environment.

Especificaciones técnicas

What Is a JIC Male 74° Cone Fitting for R5 Hose?

A JIC male 74° cone fitting is a crimp-on hose fitting with a male UNF thread and an external 74° cone at the port end. The 74° figure is the included angle of the cone, with each flank 37° from the axis, which is why JIC fittings are also called JIC 37 degree flare fittings. When the male cone is tightened into a female JIC 74° cone seat or swivel nut, the two cone faces contact metal-to-metal and the joint seals without O-rings, washers, or sealant.

The R5 part of the name matters at the hose end, not the port end. R5-family hose (commonly called out to SAE 100R5) uses textile reinforcement instead of steel wire, which makes it flexible, light, and easy to route on mobile equipment, air compressors, and machine tools, with a generous temperature range. Textile hose does not behave like wire hose under the ferrule: the cover is softer, the carcass compresses differently, and the reinforcement must not be cut by the ferrule teeth. The 16718-R5 stem and ferrule profile is engineered for this construction, so the crimp holds the hose firmly without crushing the textile carcass. Confirm your exact hose construction with our engineers when ordering, and the matching crimp data sheet is supplied with the order.

Dimensional Data and Threads

Full dimension drawings with A and S1 callouts are supplied as PDF and CAD (STEP/DWG) files. Because this is a crimp fitting, the two process-critical parameters are the hose insert depth and the crimp outside diameter; both are hose-series specific and are listed in the crimp data sheet that accompanies every order.

Full Dimension Table (Part Number Matrix) {#by-thread-size}

Read the table with your JIC thread (E) and your hose size (dash). The part number is the order code; copy it directly into your inquiry or purchase order. The pattern is 16718-[thread dash]-hose dash: for example, 16718-08-08(R5) has a 3/4″-16 thread and suits a -08 (12 mm) R5 hose.

The series covers the R5-hose segment of the JIC male range. Confirm your hose construction and the matching crimp data sheet with our engineers before ordering, and the correct insert depth and crimp outside diameter will be supplied with the order.

Material and Heat Treatment

Cold forging preserves the grain flow of the steel, which raises fatigue resistance under pressure pulsation. Each heat-treatment batch is hardness-tested and recorded, so the hardness number on the MTR matches the parts you receive.

Presión de trabajo

The exact rating for your part number and hose combination is confirmed on the datasheet and by our engineers before shipment.

Pressure-Temperature Operating Envelope

The steel fitting body holds full rated pressure across the whole temperature window. In a crimped assembly the working pressure is governed by the weakest component, normally the hose; use the hose derating curve for the system, and the fitting will not be the limiting part.

Selection and Ordering

The 16718-R5 series covers the R5-hose segment of JIC hydraulic hose fittings, from -04 to -24, and most orders can be placed directly from the tables below.

How to Read the Part Number Matrix

Find your JIC thread in the E column, then the hose dash size you use. The intersecting row gives the order code, for example a 3/4″-16 thread with a -08 hose gives 16718-08-08(R5). If your combination is not listed, send us both sizes; a custom JIC male fitting for your hose is machined on request.

JIC Thread Size Chart

Use this chart to identify any JIC fitting by its thread and to confirm the matching hose dash sizes. It is the same mapping used in the matrix above.

Cross Reference Service

Most maintenance teams buy against a legacy part number printed on the old drawing. Send us the OEM or distributor part number you currently use, with a photo of the fitting if possible. Our engineers identify the thread, cone angle, hose size, and hose family, then confirm the exact 16718-R5 equivalent before you place the order. The service covers JIC 37 degree flare fittings, JIC hydraulic hose fittings, and JIC crimp fittings in your inventory, and interchange confirmation is free. The cross reference sheet is returned in PDF for your records.

Assembly and Use Guide

Four-Step Crimping Procedure

Crimping an R5 hose fitting follows the same discipline as any JIC crimp fittings job: the crimp parameters decide everything, so never start without the data sheet.

1. Cut the hose square: use a hose cutter, never a hacksaw or an angle grinder. Textile hose frays easily, so a clean cut is even more important than on wire hose.
2. Mark the insert depth: read the insert depth for your hose series from the crimp data sheet and mark the line on the hose cover.
3. Lubricate and insert: apply a thin film of assembly lubricant to the stem and the hose bore, then push the fitting into the hose until the mark meets the ferrule.
4. Crimp and verify: select the die per the crimp table, crimp in one continuous stroke, then measure the crimp outside diameter with a caliper and compare with the tolerance.

Connecting the JIC Male End

Clean the 74° external cone and the mating female cone seat or swivel nut with a lint-free cloth. Thread the male end into the female seat by hand until the cone faces touch, then tighten the nut or stud to the torque listed for the thread size. JIC 37 degree flare fittings seal by cone contact alone, which is why the cone face must stay clean and dry. Do not use the cone as a bearing surface for a second wrench, and never apply sealant to the cone face.

Installation Warnings

• ❌ Never mix fittings and ferrules from different suppliers, even when the thread and hose sizes look identical. Stem geometry, ferrule hardness, and crimp parameters differ, and a mixed joint will leak or blow off under pressure.
• ❌ Never use a wire-hose fitting on textile R5 hose, or an R5 fitting on wire hose. The stem profiles are different, and the wrong match damages the carcass or leaks.
• ❌ Never crimp without the matching crimp data sheet. Textile hose tolerates less over-crimping than wire hose before the carcass is damaged.
• ❌ Never recrimp a fitting after a failed attempt, and never reuse a fitting removed from a hose.
• ❌ Never apply sealant to the 74° cone face. It hardens, blocks metal-to-metal contact, and contaminates the circuit.
• ✔ After assembly, pressure-test the circuit at 1.5x working pressure and inspect all joints for weepage.

OEM Customization and Quality Traceability

Quality and Traceability System

Every batch follows a documented flow: incoming steel with mill certificate → cold forging → CNC machining → heat treatment → plating → 100% thread gauge and dimension inspection → pressure test → laser marking → packing. The batch number on the carton links back to the raw material lot, the heat-treatment record, and the inspection report. Material test reports (MTR) are provided with every order on request, and third-party inspection reports (BV/SGS) can be arranged before shipment.

FAQ

Q: What is a JIC male 74° cone fitting for R5 hose? A: It is a crimp-on hose fitting with a male UNF thread and an external 74° cone, built to SAE J514 / ISO 8434-2, with a stem geometry engineered for R5-family textile-reinforced hose instead of wire-reinforced hose.

Q: What does R5 mean in the part number? A: R5 designates the hose family the stem is engineered for: textile-reinforced hose of the type called out to SAE 100R5, commonly used where flexibility, light weight, and temperature range matter more than maximum pressure.

Q: What is the 74° cone? A: The 74° figure is the included angle of the external cone, with each flank 37° from the axis, the same geometry as a female JIC 74° cone seat or swivel nut. The cone faces seal metal-to-metal, so no O-ring or sealant is used.

Q: What hose sizes does the 16718-R5 series cover? A: The series covers hose from -04 to -24 (DN 6 to 40). Confirm your exact hose construction with our engineers, and the matching crimp data sheet will be supplied with the order.

Q: Can I use a standard JIC wire-hose fitting on R5 hose? A: No. Wire-hose fittings and textile-hose fittings have different stem profiles and ferrule geometry. Using the wrong family damages the textile carcass or leaks under pressure. Always match the fitting series to the hose family.

Q: Can you provide crimp data for my hose? A: Yes. Every order includes the crimp data sheet for your hose construction, with insert depth, crimp outside diameter, and die selection. Correct crimp parameters are what separate reliable JIC crimp fittings from early failures, so we confirm them before shipment. Send us your hose series and brand, and our engineers will confirm the crimp parameters before shipment.
