  • Connections: 3/4" FIPT x 3/4" FIPT for standard threaded fittings and adapters.
  • Pressure Rating: Up to 480 psi under normal operating conditions for Schedule 40 fittings.
  • Temperature Range: Approximately 32° to 140° F for typical plumbing and irrigation use.
  • Dimensions: Nominal 3/4" pipe size with about 1.5" overall length for a compact inline join.

Easy to install and compatible with standard Schedule 40 PVC pipe and threaded adapters. For best results apply Teflon tape or an approved thread sealant to the male threads, hand-start the coupling, then tighten with a wrench for a secure, leak-resistant seal.
