Chemtrol Coupling 650133 3/4 PVDF Schedule 80 360 psi

Chemtrol PVDF Schedule 80 Coupling

This Chemtrol coupling joins two 3/4 inch female NPT pipes in chemical and industrial plumbing systems. The polyvinylidene fluoride body resists a wide range of corrosive fluids. It is rated for Schedule 80 piping and carries a maximum operating pressure of 360 psi at 73 degrees Fahrenheit. Buyers needing a different pipe size or material should look elsewhere.

Sustained pressure and temperature performance

The fitting maintains its 360 psi rating at the baseline temperature of 73 degrees Fahrenheit. As system temperature rises toward the 280 degrees Fahrenheit limit, allowable working pressure decreases according to standard PVDF derating curves. Continuous operation at elevated temperature and pressure remains within the Schedule 80 design envelope. Installations requiring higher pressure at maximum temperature need a different pressure class.

Thermal range and material stability

The coupling operates continuously from 73 to 280 degrees Fahrenheit without degradation of the PVDF body or included seal. The thermoplastic construction adds no mechanical noise to the pipeline. Wall thickness follows Schedule 80 dimensions for the 3/4 inch nominal size, providing the required pressure boundary. Systems outside this temperature window require alternative materials.
