Sk 19781 Pipe Plug Socket Set 11 Pc 3/16-3/8 in

Product Description

The SK 19781 is an 11-piece pipe plug socket set designed for installing and removing square-drive pipe plugs in plumbing, HVAC, and mechanical systems. The set covers male and female pipe plug sockets ranging from 3/16 inch to 3/8 inch, all driven by a 3/8 inch drive. Each socket features a 4-point geometry that grips pipe plug heads securely, reducing cam-out during installation and removal. Sockets are chrome-plated for corrosion resistance. The full set weighs 0.93 pounds and stores on an included clip rail for organized access in a toolbox or service van.

This set suits plumbers, pipefitters, HVAC technicians, and general mechanical tradespeople who regularly work with threaded pipe plugs in tight quarters. The range from 3/16 inch to 3/8 inch covers the most common residential and light commercial pipe plug sizes. The 3/8 inch drive makes the set compatible with standard ratchets, extensions, and torque wrenches already in most trade tool kits. Both male and female drive configurations are included, covering the two most common pipe plug head styles encountered in the field.

Installation Notes

Licensed plumbers and pipefitters typically use pipe plug socket sets when sealing or capping threaded ports in pressurized systems. Always depressurize and drain the system before removing or installing pipe plugs to prevent injury or leaks. Use an appropriate torque wrench to avoid over-tightening, which can crack fittings or strip threads. Follow applicable codes such as the IPC or IFGC for pipe plug specifications in gas and water systems.
