Question by: Eddie H on Apr 27, 2025, 12:42 PM
This looks like it'd work for hooking up a pressure gauge at a 90-degree angle. Is that right?
Answer by: Customer Support on Apr 29, 2025, 8:21 AM
Yes, that's a common use. This steel adapter has a 90-degree elbow and female NPT threads on both ends to help you hook things up in tight spots.
Question by: Roger M on Mar 24, 2026, 11:14 AM
What all industries is this elbow adapter actually built for? Got a few different use and trying to figure out if one part covers multiple applications.
Answer by: Customer Support on Mar 26, 2026, 6:40 AM
Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this fitting. That kind of range makes it a solid pick when you're sourcing across multiple environments without wanting to stock a dozen different adapters.
Question by: Roger C on Jan 10, 2026, 2:34 PM
trying to hook up two 1/4 npt female ends but need to turn the line 90 degrees, is that what this fitting does
Answer by: Customer Support on Jan 11, 2026, 4:23 PM
Function-wise, it is a 90 degree elbow adapter with 1/4-18 female NPT on one side and a 1/4-18 female NPT swivel (NPSM internal pipe swivel style) on the other, so it’s meant for making a right-angle connection between two 1/4-18 female threaded ports.
