trying to swap out an old elbow, what threads are on each end of this 04MJ-02MP?

Answer by: Customer Support on Feb 12, 2026, 2:32 PM

On the B1 end you get a male JIC SAE 37 degree flare thread in 7/16-20, built to SAE J514. The B2 end is a male NPTF pipe thread in 1/8-27, built to SAE J476.

So, this here's got two different kinds of threads on it, right? What kinda stuff are they good for?

Answer by: Customer Support on Nov 21, 2025, 11:19 AM

This elbow fitting uses a male JIC SAE 37-degree flare on one side and male NPTF threads on the other. The JIC side is commonly used in hydraulic systems where you need a reliable seal, while the NPTF is often found in applications needing a dry seal without sealant.

rated to 6,000 PSI dynamic -- does that hold up running a hydraulic line that sees pretty regular pressure spikes, or is that the ceiling you don't want to push past?

Answer by: Customer Support on May 24, 2025, 6:17 AM

6,000 PSI is the maximum dynamic pressure rating for this fitting, so that number already accounts for pressure conditions in active hydraulic systems rather than just static loads. Forged steel construction gives it solid resistance to mechanical stress, which helps when a line cycles through pressure changes repeatedly. That said, staying reasonably below the rated ceiling during normal operation is always the smarter way to protect any fitting long term.
