Performance
Working pressure matches the host port grade and the lowest-rated component in the assembly. Operating temperature -40°C to +120°C.. JIC family — SAE J514 / ISO 8434-2 — 37° cone seat with UN/UNF threads. The dominant North-American hydraulic adapter family. Metal-on-metal seal, no soft seal needed.
Applicable Standards
- SAE J514
- ISO 8434-2
How to order
Specify (a) the host port size and thread spec on each end, (b) any special seal requirements (bonded seal vs ED seal vs cone seat), and (c) whether you need stainless-steel construction or non-standard surface treatment. Indus engineering will confirm the correct part number against your equipment.
Companion products
Pair with the appropriate Indus tubing or hose ends. For tube assemblies use Indus DIN 2353 cutting rings and end nuts. For hose assemblies pair with Indus crimp ferrules and the matching hose grade.

Thread & fitting identification
Photographing a fitting so someone can identify it without holding it
Four photographs and one measurement identify almost any hydraulic fitting remotely. Most requests arrive with one photograph taken at arm’s length, and that one settles nothing.

Assembly, crimping & certification
How tight is tight: make-up torque and turns from finger tight
Nobody carries a torque wrench up a boom. The method that works without one is a published one, it is specific to each connector family, and it is the reason two fitters get different results on the same joint.

Why a new hose assembly weeps, and what to check before blaming the crimp
A hose fitted this morning is damp by the afternoon. The crimp is the last thing to suspect, not the first — and there are five checks ahead of it that take a minute each.
