Value Collection MSC-04662029 Pipe Tap 1/8-27 Npt Hss

Product Description

The VALUE COLLECTION MSC-04662029 is a standard NPT pipe tap designed to cut internal tapered threads in pipe fittings, couplings, and threaded ports. Built from high-speed steel with a bright uncoated finish, this tap is suited for general-purpose threading in ferrous and non-ferrous materials. The 1/8-27 NPT thread specification covers one of the most common small-diameter pipe thread sizes found in plumbing, HVAC, and pneumatic applications. With 4 flutes and a regular hook geometry, the tap provides balanced cutting action and adequate chip clearance for hand or machine tapping operations. Plumbers, pipefitters, HVAC technicians, and machinists regularly reach for this size when chasing or cutting fresh threads in 1/8-inch pipe ports.

This tap is intended for use in workshops, field service, and light manufacturing environments where 1/8-27 NPT threads are required. Typical applications include threading ports in manifolds, valve bodies, fittings, and equipment enclosures. The tapered NPT profile creates a pressure-sealing thread without requiring a separate sealant ring, making it well suited for gas and liquid piping connections in residential and light commercial mechanical systems.

Key Features

• 1/8-27 NPT tapered thread standard for pressure-sealing pipe connections
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 4-flute design with regular hook for balanced chip evacuation
• Bright uncoated finish for easy visual inspection of cutting edge condition
• 0.4375-inch shank diameter fits standard tap wrenches and chucks
• 0.75-inch thread length provides adequate engagement depth for pipe port threading

Compatibility

Designed for use wherever a 1/8-27 NPT internal thread is required; compatible with standard tap wrenches, T-handle drivers, and CNC or drill press tap holders accepting a 0.4375-inch shank diameter.

Installation Notes

This tap is installed by a machinist, pipefitter, or HVAC technician using a standard tap wrench or appropriate machine holder. Before tapping, drill the correct tap drill size for 1/8-27 NPT per published thread data and apply a suitable cutting fluid to reduce heat and extend tap life. Back the tap out periodically to break and clear chips, especially in blind holes. Do not force the tap past resistance, as high-speed steel taps are susceptible to breakage under excessive torque.
