Manufactured from stainless steel, this 3/4-14 male NPT to 1/2-14 female NPT bushing is designed to reduce pipe thread connections in industrial hydraulic and fluid systems. The Stainless Steel Adapter, 3/4-14 Male NPT To 1/2-14 Female NPT, Bushing from SSP Fittings Corp provides a straightforward threaded transition between two standard NPT sizes, with an overall length of 1.17 inches.
Stainless steel construction offers corrosion resistance suited to demanding fluid handling environments where carbon steel fittings may be inadequate. The bushing configuration accepts a 1/2-14 female NPT connection on one end while threading into a 3/4-14 male NPT port on the other, making it a practical solution for adapting between mismatched thread sizes without additional components.

Question by: Cheryl E on Feb 9, 2026, 6:44 AM
Got a 3/4 NPT port on a pump housing and need to run 1/2 inch line off it. this bushing do the trick for that kind of hookup?
Answer by: Customer Support on Feb 11, 2026, 6:32 AM
That's exactly what it's built for. The bushing threads into a 3/4-14 male NPT port on one end, and the 1/2-14 female NPT opening on the other end accepts your half-inch line. One piece, no extra adapters needed, and at just over an inch long it keeps things compact. Stainless construction holds up well in fluid systems where a standard carbon steel fitting might not cut it.

got a 3/4-14 npt port but my line is 1/2-14 npt. is this the right bushing to step it down
Answer by: Customer Support on Sep 28, 2025, 11:02 AM
For stepping down between standard NPT sizes, this bushing threads into a 3/4-14 male NPT port on one side and provides a 1/2-14 female NPT connection on the other.
Question by: Duane B on Feb 24, 2026, 10:54 AM
Will this fitting hold up if I'm using it for hydraulics on a farm? Don't want it rusting out on me.
Answer by: Customer Support on Feb 26, 2026, 8:35 AM
Because it's made from stainless steel, this adapter offers good corrosion resistance, which is what you want in demanding fluid handling jobs where regular steel just won't cut it.
