trying to swap out an elbow on a small line, what size threads are on each end of this 3400X4X2?
Answer by: Customer Support on Oct 1, 2025, 6:44 AM
On this street elbow, one end is a 1/8 NPTF male and the other end is a 1/4 NPTF female.
Question by: Denise P on Jun 26, 2025, 3:45 PM
brass fitting rated for hydraulic use, or is this more of a hydraulic connections part?
Answer by: Customer Support on Jun 28, 2025, 6:07 AM
Hydraulic systems are a listed application for this fitting, right alongside instrumentation and refrigeration lines. It's made from brass and carries both SAE 130239 and ASME certifications, so it meets recognized industry standards rather than being a basic hydraulic connections-grade piece. The Dura-Kote plating also gives it better corrosion resistance than a standard brass fitting off a hardware shelf.

What kind of stuff is this elbow fitting good for?
Answer by: Customer Support on May 22, 2025, 3:43 PM
Typically, this 90° street elbow is used for grease, refrigeration, instrumentation, and hydraulic systems. It's also available for fuel, LP, and natural gas, but that's on a special order basis.
