Designed for secure leak-resistant connections
Adapters for semi-rigid tubing are color-coded by tubing size for easy identification. Each connection is comprised of a two-piece nut and ferrule system with polypropylene NPT(M) thread adapter. Wrap NPT thread 3 to 4 times with PTFE tape and wrench tighten for a leak-resistant connection. Adapters withstand pressures up to 500 psi.
