Spears 3639-007C TU 2000 Standard CPVC Ball Valve

Spears 3639-007C True Union 2000 Standard Ball Valve is a 3/4 in CPVC ball valve designed for CPVC piping systems with a socket end on one side and FNPT threading on the other (SOC/FPT). The CPVC body delivers reliable chemical resistance for fluid service in industrial piping, while FKM (fluoroelastomer) O-rings and seats provide durable sealing in this size. As part of Spears' TU 2000 True Union line, the two-piece body and union nut enable quick disassembly for maintenance or seat/ball replacements without removing adjacent piping, a practical feature for modular or retrofit installations. The part number 3639-007C identifies the CPVC variant with FKM soft goods, and a typical listing places its maximum pressure at 235 psi. This configuration—socket and FNPT ends—supports flexible installation options, making it suitable for piping runs that require a transition from socket-welded CPVC to threaded connections while delivering reliable shutoff and long service life in corrosive environments.
