Value Collection MSC-04665022 Pipe Tap 1/8-27 Nps

Product Description

The VALUE COLLECTION MSC-04665022 is a standard pipe tap ground to the NPS (National Pipe Straight) thread standard in a 1/8-27 thread size. It is used to cut internal pipe threads into metal workpieces, allowing standard pipe fittings to be threaded directly into housings, manifolds, ports, and similar components. Ground from high-speed steel with a bright, uncoated finish, this tap delivers reliable cutting performance across a range of ferrous and non-ferrous materials. The 4-flute design provides good chip clearance and thread form stability during hand or machine tapping operations. Thread length is 0.75 inches, shank diameter is 0.4375 inches, and the square drive measures 0.328 inches.

This pipe tap is suited for plumbing, HVAC, and mechanical service work where NPT or NPS threaded ports need to be created or restored in metal parts. Typical applications include tapping pressure tap points, sensor ports, drain plugs, and fitting seats in equipment such as boilers, heat exchangers, manifolds, and piping assemblies. It is used by plumbers, pipefitters, HVAC technicians, and machinists working in both residential and light commercial settings.

Installation Notes

This tap should be installed using a properly sized tap wrench or tapping head. Always ensure the workpiece is securely fixtured before beginning the tapping operation. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Back the tap out periodically to break chips and prevent binding.
