These adapters are designed specifically to make reliable connections to female 1/8 inches and 1/4 inches National Pipe Thread (NPT) ports. Manufactured from biocompatible PEEK, NPT Adapters are durable and chemically resistant. We provide versions with either 1/4-28 or 5/16-24 flat-bottom threads, suitable for most low pressure applications.
Our NPT (National Pipe Thread) Adapter Assembly is specifically manufactured from PEEK making it durable and chemically resistant. Our NPT Adapter is exceptionally useful for attaching 1/8 inches outer diameter fluoropolymer sparging lines to sparging gas tank regulator valves.
