Victaulic L012005GE0 Firelock Rigid Coupling 1-1/4 in

Product Description

The VICTAULIC COMPANY L012005GE0 is a Style 005 FireLock Rigid Coupling designed for grooved-end pipe connections in fire protection and industrial piping systems. Constructed from ductile iron conforming to ASTM A536 Grade 65-45-12, this coupling features a hot-dipped galvanized finish for corrosion resistance. It handles a maximum working pressure of 350 psi and accommodates a nominal pipe size of 1-1/4 inches with an outside diameter of 1.66 inches. The rigid coupling design maintains pipe alignment and restricts angular and linear movement at the joint, making it a standard choice for licensed sprinkler contractors and industrial piping crews.

This coupling is used in grooved piping systems where rigid joints are required, including fire suppression, HVAC, and industrial process piping. The hot-dipped galvanized finish makes it suited for exposed or corrosive environments. It ships with a Grade E gasket and two 3/8-inch by 2-1/4-inch bolts and nuts, providing a complete, field-ready assembly. Installation is appropriate for both new construction and retrofit applications where UL, CUL, FM, LPCB, or VDS approval is required.

Installation Notes

Installation should be performed by a licensed fire sprinkler contractor, pipefitter, or qualified tradesperson in accordance with NFPA 13 and local authority having jurisdiction requirements. Depressurize and isolate the pipe section completely before assembly or disassembly. Ensure pipe ends are properly grooved to manufacturer specifications before seating the gasket and engaging the coupling housing. Do not overtighten bolts beyond the point of metal-to-metal housing contact.
