00018 Hose Ferrule for SAE 100 R7 Thermoplastic Hose

The 00018 R7 hose ferrule is a one-piece, no-skive crimp sleeve engineered for SAE 100 R7 thermoplastic hydraulic hoses. It covers seven dash sizes from 03 to 12 (DN 5 to 20), with ferrule lengths up to 43 mm, making it the go-to choice for control circuits, lubrication lines, and low-pressure hydraulic systems. This page lists every dimension, material spec, crimping requirement, and ordering detail you need to spec the right part.

What Is the 00018 R7 Hose Ferrule?

An R7 hose ferrule is the outer metal shell of a thermoplastic hose fitting. SAE 100 R7 hoses use a smooth thermoplastic tube with fiber reinforcement, so the ferrule must grip the cover firmly without damaging it. The 00018 ferrule meets that demand with three annular grooves on the inner bore that lock onto the hose cover during crimping.

This R7 hose ferrule uses a no-skive design, so the thermoplastic cover stays intact during assembly. Our in-house tests show that correctly crimped 00018 assemblies hold beyond the hose’s rated working pressure without leakage or fitting pull-out.

Core advantages:

• Built for SAE 100 R7 thermoplastic hoses in the 03-12 dash range
• Three annular grooves grip the cover firmly without damaging it
• No-skive design: skip the skiving step and cut assembly time
• Outer diameter (D) is held to tight tolerance for predictable die selection
• Yellow zinc plating protects against corrosion in service
• Matched ferrule-and-stem sets for consistent, certified assemblies

Key Specifications and Dimensions

All 00018 ferrules share one cylindrical, hollow-body geometry with three annular grooves on the inner bore. Length (L) and outer diameter (D) are the key R7 hose ferrule dimensions, matched to each hose dash size.

• Length tolerance: ±0.5 mm across the range
• Outer diameter tolerance: ±0.1 mm for consistent crimp die selection
• Designed for hoses whose cover O.D. conforms to SAE 100 R7

Applicable standard: SAE J517 (100 R7).

Crimp diameter note: the final crimped O.D. is set by your hose maker’s crimp chart, not by the ferrule alone. The tight O.D. tolerance of the 00018 ferrule keeps crimp results stable from batch to batch. Always verify the target crimp diameter against the hose manufacturer’s published chart before production runs.

Material and Surface Finish

• Base material: carbon steel, cold formed for uniform grain structure
• Surface treatment: yellow zinc plating with yellow chromate passivation
• Corrosion resistance: typical neutral salt spray performance ≥120 h per ISO 9227; zinc-nickel plating available for offshore or high-corrosion service
• Hardness: balanced to resist cracking during crimping, typically HRC 20-25; certified values on request
• Inner bore: three precision-formed annular grooves for a firm grip on the thermoplastic cover

For food, pharmaceutical, or highly corrosive media, we also supply this R7 hose ferrule in stainless steel on request.

Performance and Crimping Requirements

Working and burst pressure values below follow SAE 100 R7 for the assembled hose. The ferrule is designed to hold the assembly to the hose’s rated performance.

• Temperature range: -40 °C to +93 °C for continuous service
• Crimping type: no-skive, one-piece crimp
• Equipment: the 00018 R7 hose ferrule works with standard hydraulic crimping machines and matching die sets
• Reuse: ferrules are single-use components. Never re-crimp a used ferrule.

Application Guide: Where R7 Assemblies Fit

We are transparent about where this product fits. SAE 100 R7 is a thermoplastic hose family for control circuits, lubrication lines, instrumentation, machine tools, and other low-pressure hydraulic service. It is not rated for heavy high-pressure hydraulics or continuous service above 93 °C. For high-pressure rubber and steel-wire hoses, use our braided or spiral ferrule series instead.

If you are unsure whether R7 matches your application, send us your working pressure, temperature, and media, and our engineers will recommend the right hose family and ferrule series before you order.

Installation Guide

1. Cut the hose square with a sharp hose cutter. A square cut prevents leakage paths and uneven grip.
2. Measure and mark the insertion depth on the hose cover.
3. Insert the matching stem fully into the hose bore.
4. Slide the 00018 ferrule over the hose end and seat it against the stem shoulder.
5. Position the assembly in the correct die set and crimp to the target crimp diameter.
6. Verify the crimp O.D. with a caliper. Record the value for quality traceability.

Matching components: the 00018 ferrule is designed to pair with the matching 00018-series stem (insert) from the same fitting family. We supply ferrule and stem as matched sets, which is the recommended way to achieve consistent, certified assemblies.

How to Select the Right Ferrule Size

Selecting the right R7 hose ferrule size starts with the dash size.

• Step 1: Confirm the hose is SAE 100 R7 with a standard cover O.D.
• Step 2: Match the dash size to the hose I.D. (03 = 5 mm, 04 = 6 mm, and so on).
• Step 3: Cross-check the ferrule O.D. (D) against your die set and the target crimp diameter on the hose maker’s chart.

When in doubt, send us the hose brand, dash size, and crimp machine model. Our engineers will confirm the correct 00018 part number and crimp data before you order.

Quality Control and Testing

• Dimensional inspection with calibrated gauges on every R7 hose ferrule batch
• Batch salt spray testing to verify plating quality
• Pull-off and burst testing on sample assemblies to validate grip performance
• Batch traceability marking on packaging

Warranty and honesty: we guarantee workmanship and material defects, and we replace defective parts without question. Assembly quality depends on correct hose preparation and crimp settings, which remain the assembler’s responsibility. We share our crimp data openly and support you through first articles.

FAQ

Q: Which hose does the 00018 R7 hose ferrule fit? A: Thermoplastic hoses manufactured to SAE 100 R7 in dash sizes 03 to 12 (DN 5 to 20).

Q: Is R7 the right hose family for my application? A: R7 suits control circuits, lubrication, instrumentation, and other low-pressure hydraulic service up to 3,000 psi. For heavy high-pressure hydraulics, choose our braided or spiral ferrule series instead.

Q: Is this a skive or no-skive ferrule? A: No-skive. The three annular grooves grip the intact thermoplastic cover, so no skiving is required.

Q: Can the ferrule be reused after a hose fails? A: No. Hydraulic ferrules are single-use components. Always crimp a new ferrule for every new assembly.

Q: What crimp diameter should I use? A: Use the target crimp diameter from your hose manufacturer’s crimp chart for the specific dash size. We provide reference crimp data with every order.

Q: Do you provide samples and custom finishes? A: Yes. Sample kits, zinc-nickel plating, stainless steel, and private label options are all available.
