Product Questions & Answers (2)

Question by: Diane A on May 14, 2025, 8:02 AM
got a 1-1/4 NPTF male port on a manifold. will this bushing step it down to a 1 inch NPTF female?
Answer by: Customer Support on May 15, 2025, 1:27 PM
Yes, it is a pipe to pipe steel bushing with a 1-1/4-11-1/2 male NPTF on one end and a 1-11-1/2 female NPTF on the other, so it adapts from that larger male thread to the smaller female thread size.
Question by: Clint H on Feb 7, 2026, 2:59 PM
Reckon this'll work alright for hooking up some grease lines to my equipment?
Answer by: Customer Support on Feb 9, 2026, 12:44 PM
It should, yes. This adapter is designed for grease and instrumentation systems, so it's built to handle those kinds of applications.
