Got a 3/4 inch NPT port on a manifold block and need to tie into 1/2 inch NPT line, this bushing handle that?
Answer by: Customer Support on Aug 3, 2025, 8:15 PM
Yeah, that's exactly what this fitting is built for. The male end threads into your 3/4 inch NPT port, and the female end accepts a 1/2 inch NPT fitting or pipe. Eaton Aeroquip makes this one from aluminum with a blue anodized finish, so it's reasonably lightweight and corrosion resistant. Just make sure your fluid is compatible with aluminum before you run with it, Eaton does publish a fluid compatibility document for this product line if you need to cross-check a specific media.

Will this adapter hold up alright if I'm usin' it with hydraulic fluid?

This adapter is made from anodized aluminum, but you'll want to check Eaton's fluid compatibility document to make sure it's good to go with the specific hydraulic fluid you're planning to use. That document should have all the details you need to confirm compatibility.

got a 3/4 npt port but my line is 1/2 npt. is this the bushing i need?
Answer by: Customer Support on Sep 23, 2025, 4:01 PM
It steps the pipe thread sizes down from 3/4 inch male NPT on the outside to 1/2 inch female NPT on the inside, so it’s used when you need to adapt a 3/4 NPT opening to accept a 1/2 NPT male connection.
