Product Questions & Answers

what's the pressure rating on this union, and is it safe to run in a hydraulic line that sees regular pressure spikes?

Question by: Howard T on Aug 25, 2025, 3:09 PM

Rated at 6,000 psi maximum dynamic pressure, this fitting can hold up well in lines that see regular working load. Dynamic ratings already account for the kind of fluctuation you'd see in active hydraulic systems, so it's not just a static number. Both ends carry a male JIC SAE 37-degree flare, which is a proven sealing design in high-pressure hydraulic work. As long as your system stays within that 6,000 psi ceiling, you're in good shape with this one.

trying to swap a fitting out, are both ends on this union male JIC 37 degree flare?

Question by: Rusty A on Oct 16, 2025, 11:26 AM

Both sides are male JIC SAE 37 degree flare, built to SAE J514 thread specs, so it is meant to join two female JIC flare ends in a straight union.

Reckon this union will hold up in a hydraulic system pushing close to that 6,000 psi rating?

Question by: Jean H on Oct 25, 2025, 5:40 PM

Absolutely, this union is designed to handle dynamic pressures up to 6,000 psi, making it suitable for demanding hydraulic applications.
