Product Questions & Answers (2)
Question by: Dean M on May 18, 2025, 3:53 PM
what's the thread size on both ends of this connector? trying to match it up to some 1/4 inch fittings already on the machine
Answer by: Customer Support on May 20, 2025, 1:53 PM
Both ends on this one are 1/4 inch. One end is NPTF threaded for your pipe or port connection, and the other end is the hose or tube side. So if you're working with 1/4 inch lines on both ends, you're in the right ballpark for a straight drop-in connection.
Question by: Brent B on Jan 2, 2026, 7:41 PM
Will this work with standard NPT fittings?
Answer by: Customer Support on Jan 4, 2026, 6:37 AM
It's designed with a female NPTF end, so it should be compatible with standard NPT fittings. Just make sure the sizes match up correctly.
