Grooved Cap – Fire Protection Pipe Fitting

Heavy-duty grooved cap fitting for sealing pipe ends in fire protection systems. Made from ductile iron with grooved-end connection for easy, weld-free installation. Ideal for terminating fire sprinkler piping in wet, dry, and deluge systems. Compatible with all standard grooved coupling systems.

The Grooved Cap is a reliable pipe end fitting used to seal off unused or terminated pipe sections in fire protection systems. Constructed from rugged ductile iron, it features a grooved-end connection that allows fast installation with grooved couplings—eliminating the need for welding or threading.

This cap is widely used in wet pipe systems, dry systems, pre-action, and deluge sprinkler setups, providing a secure and corrosion-resistant solution for system closure. With a working pressure rating of up to 300 PSI, it supports long-term performance in both commercial and industrial applications. UL/FM certifications may apply depending on size and specification.
