Chemtrol 6503 Adapter Coupling 1 1/2 in S x FPT Schedule 80

Chemtrol Schedule 80 Adapter Coupling

The Chemtrol 6503 adapter coupling joins 1 1/2 inch Schedule 80 pipe using a socket end and a female NPT thread. It is built from polyvinylidene fluoride for chemical resistance in industrial plumbing systems. The red fitting includes a seal and measures 2 31/64 inches overall length. Suitable for new installations requiring a durable transition between socket and threaded connections.

Pressure and temperature headroom

Rated for 360 psi maximum operating pressure at 73 degrees Fahrenheit, the coupling handles typical Schedule 80 service conditions. The material remains stable up to 280 degrees Fahrenheit, giving headroom for hot fluid lines. Above that temperature the pressure rating drops and the fitting should not be used. It is not for systems exceeding the stated pressure or temperature limits.

Socket by female NPT configuration

The single deciding specification is the S x FPT connection type: one 1 1/2 inch socket end and one 1 1/2 inch female NPT thread. This matches only pipe and components with the same nominal size and thread standard. Buyers needing a different end combination or a larger diameter must select another fitting.
