Product Questions & Answers (3)

Question by: Merle T on Dec 1, 2025, 9:16 PM
What size is this black nipple? Just wanna make sure it's what I need.
Answer by: Customer Support on Dec 3, 2025, 9:56 AM
This pipe nipple measures 3/8 X 2 1/2 inches, making it suitable for connections requiring that specific size.
Question by: Patty P on Mar 31, 2025, 8:28 PM
got a 3/8 line that needs a short extension to reach a fitting, is 2 and a half inches gonna be enough to work with, or should I be looking at something longer?
Answer by: Customer Support on Apr 1, 2025, 9:48 PM
For most close-quarters connections, 2.50 inches gives you a usable amount of thread-to-thread distance without a lot of excess sticking out. The male NPT threads on both ends are 3/8-18, so as long as your fittings match that thread spec, it should reach. Whether the length suits your specific setup depends on the gap you're bridging, but this is a pretty common size for tight inline connections.
Question by: Lynn T on Jan 5, 2026, 11:18 AM
