National Pipe Thread Adapters
These adapters are designed specifically to make reliable connections to female 1/8” and 1/4” 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.
