Question by: Brent B on Mar 25, 2025, 1:15 PM
trying to hook up a tight spot, is this the 90 degree elbow with 1/4-18 female npt on one end and 1/4-18 male npt on the other?
Answer by: Customer Support on Mar 27, 2025, 8:15 AM
Thread-wise it is a 90 degree street elbow that goes 1/4-18 female NPT to 1/4-18 male NPT, and it is built for NPTF style connections on both ends.

Will this fitting hold up alright for hooking up some gauges to my hydraulic system?

Designed for instrumentation and hydraulic systems, this brass adapter should work fine for connecting gauges. Just make sure the 1/4-18 NPT thread size is compatible with your setup.

what all systems is this brass elbow rated for? I got a hydraulic line I'm trying to reroute and need something that'll hold up
Answer by: Customer Support on Jun 6, 2025, 4:52 PM
Hydraulic systems are one of the listed applications for this adapter, along with instrumentation, grease, and refrigeration systems. Fuel, LP, and natural gas are also covered, though those require a special order. For a standard hydraulic reroute, this fits right in with what it's built for.
