Question by: Kirk C on Sep 21, 2025, 12:17 PM

got a 1/2-14 nptf port and need to step down to 1/4-18, is that what this hex nipple does?

Answer by: Customer Support on Sep 22, 2025, 12:21 PM

For stepping between sizes, this part is a straight steel hex nipple with male NPTF threads on both ends. One side is 1/2-14 (B1) and the other is 1/4-18 (B2), both to SAE J476, so it’s meant to connect those two female NPTF ports.

Question by: Marvin F on Jan 3, 2026, 5:44 PM

does this thing go between a 1/2 inch line and a 1/4 inch line, or am I reading the thread sizes wrong?

Answer by: Customer Support on Jan 5, 2026, 6:26 AM

You're reading it right. One end is 1/2-14 NPTF and the other is 1/4-18 NPTF, so it steps down between those two sizes. Both ends are male threads, so you'd be threading this into female NPTF ports on each side. It's a reducer nipple, not a coupler, so make sure your fittings on both ends are female before you order.

Will this nipple work for hooking up a quarter-inch line to a half-inch port?

Designed to adapt between different NPTF thread sizes, this hex nipple features a 1/4-18 thread on one end and a 1/2-14 thread on the other.
