Question by: Terry Y on Feb 15, 2026, 9:51 PM
trying to swap out an old nipple, is this one 1 inch male NPT and 4 inches long?
Answer by: Customer Support on Feb 17, 2026, 10:07 AM
Specs-wise, it matches a 1-11-1/2 male NPT thread and a 4.00 inch length, so it lines up with what most folks mean by a 1 inch male NPT by 4 inch nipple.
