So this here adapter...it'll go from a 3/4-16 SAE O-ring to a 1/2-14 NPT, right? Just wanna make sure I'm readin' this thing right.

That's correct. It adapts a 3/4-16 male SAE O-ring boss to a 1/2-14 male NPT connection.

got a hydraulic line running 3/4-16 straight thread on one end and need to tie into a 1/2 NPT port on a pump housing. this the right fitting for that?
Question by: Larry W on Jan 11, 2026, 5:09 PM
That connection is exactly what this adapter is built for. One end is 3/4-16 Male SAE O-Ring Boss, the other is 1/2-14 Male NPT, so it bridges those two thread standards in a straight configuration. The SAE O-Ring Boss end seals against an o-ring at the boss port, while the NPT end uses thread engagement at the pump housing. No sealant is included with the fitting, so you'll want to apply your own thread sealant on the NPT side before installation.

got a hose end with 3/4-16 ORB on it and the valve i’m tying into is 1/2-14 npt. is this the right adapter?
Question by: Tommy P on Oct 14, 2025, 7:19 AM
For that combo, it matches up. One side is 3/4-16 Male SAE O-Ring Boss (straight thread O-ring) and the other side is 1/2-14 Male NPT, and it is a straight steel adapter.

trying to hook an ORB port up to a pipe thread line, is this the right adapter?
Question by: Jimmy H on Nov 6, 2025, 3:40 PM
For tying those two thread styles together, it’s a straight steel adapter with a 3/4-16 male SAE O-ring boss on one side and a 1/2-14 male NPT on the other, so it’s meant to bridge an ORB connection to an NPT connection.

What size are the threads on this adapter, I just want to make sure I'm getting the right thing.

This adapter features a 3/4-16 Male SAE O-Ring Boss (Straight Thread O-Ring) on one end and a 1/2-14 Male NPT thread on the other. That's the long and short of it.
