90 Degree SAE O-Ring Boss Swivel Male Hydraulic Hose Fitting: 16091KSW Series (ISO 11926 / SAE J1926)

Why This 90 Degree SAE O-Ring Boss Swivel Male Hydraulic Hose Fitting Passes the Compliance Gate

The 16091KSW is a 90 degree SAE O-ring boss swivel male hydraulic hose fitting that combines a right-angle elbow with the straight-thread O-ring sealing system of ISO 11926 and SAE J1926. Because the threaded nose sits on a rotating hex nut, the elbow can be turned to face any direction after crimping, so the hose leaves the port at exactly the angle your routing needs without being twisted into place. For OEMs, distributors and maintenance crews this collapses two problems into one part: changing direction around the machine and aligning an O-ring boss port without winding the hose.

Core Advantages

1. 90-degree bend plus swivel nut in one body – direction change and port alignment are solved by a single fitting, reducing part count and leak points.
2. SAE J1926/ISO 11926 O-ring face seal – the groove-mounted O-ring seals on the flat boss face while UNF straight threads provide retention.
3. Engineered for braided hose – tail dashes -06 to -10 with 3/4″-16 and 7/8″-14 thread ends cover compact excavator, agricultural and industrial routings.
4. Full process traceability – 100% pressure test, thread inspection and batch records on every order.

Technical Specifications

What Is a 90 Degree SAE O-Ring Swivel Hose Fitting?

A 90 degree SAE O-ring boss swivel male hydraulic hose fitting routes the hose through a right angle and terminates it on a swivel-style ORB male end. The elbow body carries the hose tail on one axis, while the other axis ends in a straight-thread nose with an O-ring groove mounted on a rotating hex nut. You crimp the hose, swing the elbow to the direction required, then run the nut into the port – the O-ring compresses against the machined boss face and forms the seal without the hose ever being rotated.

The head follows the SAE J1926 / ISO 11926 O-ring boss system, dimensionally consistent with the straight 16011 and 16011SW families, so the same ports and O-ring-to-thread-dash rules apply. It is not compatible with JIC 37-degree (SAE J514) or 45-degree flare (SAE J513) cone ports, which use tapered metal faces instead of an O-ring. If you are specifying a 90 degree SAE O-ring boss swivel male hydraulic hose fitting for the first time, check dimension H against the surrounding structure and confirm the nut hex S2 stays reachable with your torque wrench.

Dimensional Data

Full Dimension Table (Part Number Matrix)

All dimensions are in millimetres. Each part number reads as 16091KSW - thread dash - hose dash; for example 16091KSW-10-08 means a 7/8″-14 thread end with a -08 hose tail. Threads are shown as in the original chart and are UNF straight threads (for example 3/4″X16 = 3/4″-16 UNF). The O-ring code always follows the thread dash: O908 for -08 and O910 for -10.

Factory note: the 16091KSW series is produced for braided hose assemblies. If your routing needs spiral hose or a larger bore, contact our engineers for the correct elbow configuration before ordering.

Material and Heat Treatment

Working Pressure and Operating Envelope

Working pressure is set jointly by the SAE J1926 port standard and the grade of braided hose you crimp; HENGHUA does not publish a standalone elbow rating because the assembly is only as strong as its weakest member. Every 16091KSW assembly leaves the factory after a 100% pressure test, and the torque and crimp-diameter data sheet for your hose is supplied with the order. The same validation applies to every SAE O-ring boss swivel male hydraulic hose fitting in the HENGHUA range, fixed or elbow. Operating temperature is typically -40°C to +120°C, with system de-rating governed by the hose and seal materials in the circuit.

Selection and Ordering

How to Read the Part Number Matrix

Read the code left to right: 16091KSW fixes the 90-degree swivel O-ring boss head, the next two digits give the thread dash (-08 or -10) and the last two digits give the hose dash (-06, -08 or -10). The O-ring code follows the thread dash one-to-one, so the O-ring column verifies any code before ordering. Because one thread size covers several hose sizes, always quote both the port thread and the hose dash together with the required bend orientation.

For elbow routings this matrix is the 90 degree SAE O-ring boss swivel male hydraulic hose fitting reference: bend height H, body hex S1 and nut hex S2 are listed so you can check the elbow clears surrounding components. A 90 degree SAE O-ring boss swivel male hydraulic hose fitting bought by code arrives with the O-ring matched to the thread and the swivel nut pre-assembled, ready to crimp.

Thread Size and Dash Chart

Cross Reference Service

Send us your old part number or a worn sample and our engineers will translate it into the correct 16091KSW code, checking thread form, O-ring dash, bend direction and swivel configuration before you order. The service is free for OEMs and distributors ordering in volume, and it removes the guesswork when you consolidate legacy elbow inventories onto one crimp system. We never attach another manufacturer’s brand to our parts.

Packaging and Logistics

Standard packing is 10 pieces per box with a batch label on every carton; export cartons are marked with part number, quantity and “Made in China – HENGHUA”. The material test report travels with each shipment and mixed part numbers can share one container to keep freight economical. Split deliveries by air can be arranged against a confirmed schedule for urgent production stops.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square – use a sharp saw and a hose cutter, then blow out any debris from the bore.
2. Mark the insertion depth – transfer the tail length from the fitting drawing onto the hose cover as a witness mark.
3. Lubricate and insert – apply a thin film of assembly lubricant to the tail and push the hose in with a slight twist until it reaches the mark.
4. Crimp and verify – crimp with the die set matched to the hose construction, then check the crimped outside diameter with a caliper against the data sheet supplied with the order.

Connecting the O-Ring Boss End

Route the hose first, swing the elbow to its working direction, then rotate the swivel nut by hand until the threaded nose starts into the port without force. Lightly coat the O-ring with clean hydraulic oil, seat the fitting against the boss face and tighten the S2 hex with a torque wrench to the SAE J1926 values given in the order-specific data sheet; use the S1 hex on the elbow body only to hold the fitting steady, never to force alignment. Never wind Teflon tape or thread sealant onto the straight threads – the O-ring is the only seal and tape debris will contaminate the circuit.

Installation Warnings

• ✔ Decide the elbow direction before tightening, then use the swivel nut to make the final alignment.
• ✔ Check the boss face is flat, clean and free of burrs before assembly.
• ✔ Confirm the elbow envelope (dimension H) clears pipes, guards and other fittings before crimping the hose.
• ❌ Do not use the hose as a lever to rotate the elbow into position.
• ❌ Do not use Teflon tape or thread sealant on the straight threads.
• ❌ Do not mix this ORB end with JIC 37-degree (SAE J514) or 45-degree flare (SAE J513) ports.
• ❌ Do not exceed the recommended torque on the swivel nut; the O-ring, not the thread, carries the seal.

Quality and Traceability System

Every heat and batch is tracked from cold heading through machining, heat treatment, plating and final test, so a batch number traces back to the material certificate. Pressure testing is 100% rather than sample-based, and the MTR is included with the order; BV or SGS witness inspection can be arranged on request.

FAQ

1. Why choose a 90 degree elbow with a swivel nut instead of a straight fitting? The elbow changes the hose direction at the port, and the swivel nut lets you aim the bend anywhere after crimping. Tight engine bays and excavator boom routings are the typical applications.

2. Is the 16091KSW seal the same O-ring system as the 16011 series? Yes. All three families use the SAE J1926/ISO 11926 straight-thread O-ring boss seal; the 16091KSW simply adds the 90-degree bend and the rotating nut.

3. Can the elbow orientation be adjusted after the hose is crimped? Yes. The threaded nose rotates on the swivel nut, so you can turn the elbow to the required direction even after the crimp is complete, as long as the nut is not yet tightened into the port.

4. Which hose can I use with 16091KSW? The series is produced for braided hose in dash sizes -06 to -10. Contact our engineers if your assembly uses spiral hose so we can specify the correct elbow.

5. Does the 90-degree bend reduce the pressure rating? Working pressure is determined by the SAE J1926 port standard together with your hose grade. Every assembly is 100% pressure tested and the torque and crimp data sheet accompanies the order.

6. Can this fitting connect to a JIC or flare port? No. JIC 37-degree (SAE J514), 45-degree flare (SAE J513) and O-ring boss (SAE J1926/ISO 11926) are separate sealing systems and their parts are not interchangeable.

7. What information do you need to quote elbow fittings? Send the part number or the thread and hose dash, the bend direction, the hose construction, the quantity and the delivery date. Our engineers reply within 24 hours with pricing and the matching data sheet.
