Product Questions & Answers

Will this plug hold up if I'm using it with some hydraulic fluid that gets pretty hot?

Question by: Jimmy W on Jun 20, 2025, 8:02 AM

Constructed from stainless steel, this adapter offers good corrosion resistance, which should help with the heat you're describing.

got a 3/8-18 npt port i need to cap off, is this the right plug?

Question by: Hubert K on Aug 23, 2025, 9:22 AM

For a 3/8-18 male NPT plug, this matches that thread size and is meant for pipe-to-pipe connections where you need to close off a port.
