Sk 41440 Female Pipe Plug Socket 3/8 Drive 5/16 Hex

Product Description

The SK 41440 is a female pipe plug socket designed for removing and installing recessed square-drive pipe plugs found in hydraulic fittings, manifolds, and fluid system components. Built with a 3/8 inch drive and a 5/16 inch hex profile, this 4-point socket engages female pipe plug heads with a secure fit that reduces slippage during high-torque removal. The 0.313 inch socket size targets the specific geometry of square-drive pipe plugs common in HVAC equipment, plumbing assemblies, and industrial fluid systems. The construction is rated for long service life and maximum corrosion resistance, making it a reliable addition to any service kit used in wet or corrosive environments.

This socket is suited for use in residential and commercial maintenance applications where recessed pipe plugs must be accessed in tight spaces. It is commonly used by HVAC technicians, plumbers, and pipefitters when servicing hydraulic manifolds, refrigerant line components, and pipe fitting assemblies. The 3/8 inch drive shank is compatible with standard ratchets, torque wrenches, and extension bars already in most trade toolkits, keeping the workflow efficient without requiring specialty equipment.

Installation Notes

This socket is installed and used by HVAC technicians, plumbers, and pipefitters working on fluid system components containing recessed pipe plugs. Before servicing any fitting, relieve system pressure and shut off fluid supply to the assembly being worked on. Use with a calibrated torque wrench when reinstalling pipe plugs to avoid over-tightening and thread damage. Follow applicable plumbing and mechanical codes, such as IPC or IFGC guidelines, when servicing pressurized piping systems.
