Spears 4235-130gs Cpvc Sprinkler Head Adapter 1 X 1/2 Inch

Product Description

The SPEARS 4235-130gs is a CPVC fire sprinkler head adapter designed for use in wet-pipe and dry-pipe fire suppression systems. Part of the FlameGuard TorqueSafe line, this fitting connects a 1-inch socket inlet to a 1/2-inch female threaded outlet and includes a gasket for a secure, leak-resistant seal at the sprinkler head connection. Manufactured from corrosion-resistant CPVC, the adapter is pressure rated to 175 psi at 150 degrees F. It is UL Listed for use in the United States and Canada and is NSF certified for potable water contact. Fire suppression contractors and plumbing professionals install this fitting as a transition point between CPVC branch piping and threaded sprinkler heads.

This adapter is intended for residential and light commercial fire sprinkler installations covered under NFPA 13, 13R, and 13D system classifications. The socket-by-female-thread configuration makes it a standard transition fitting when terminating a CPVC branch line at a sprinkler head location. Its CPVC construction offers a practical alternative to metal fittings in environments where corrosion resistance and hydraulic efficiency are priorities. The included gasket reduces the risk of joint leakage at the threaded sprinkler head interface without requiring additional sealing compounds in that connection.
