Value Collection MSC-04665055 Pipe Tap 1/2-14 Nps 4 Flute

Product Description

The VALUE COLLECTION MSC-04665055 is a standard NPS pipe tap designed to cut 1/2-14 tapered pipe threads in a range of workpiece materials. The tap is manufactured from high-speed steel (HSS) for durability and heat resistance during threading operations. It features four flutes for efficient chip evacuation and a bright, uncoated finish suitable for general-purpose threading. With a thread length of 1.375 inches and a shank diameter of 0.6875 inches, this tap is sized for use in standard tap handles and machine setups. Plumbers, pipefitters, and maintenance technicians use this tap to create threaded pipe connections in ferrous and non-ferrous materials.

This pipe tap is used when threading pipe ports or fittings to accept 1/2-inch NPS male threaded connections. Typical applications include threading bosses on pipe fittings, manifolds, valve bodies, and similar components in plumbing, HVAC, and general industrial maintenance work. The NPS (National Pipe Straight) thread standard makes it appropriate for applications where a straight-thread pipe connection is specified rather than a tapered NPT thread. This tap is suited for both hand tapping and light machine tapping operations in shop and field environments.

Key Features

• 1/2-14 NPS thread size for straight pipe thread applications
• High-speed steel construction for heat resistance and long service life
• 4-flute design promotes efficient chip removal during threading
• 1.375-inch thread length accommodates standard pipe wall thicknesses
• Bright uncoated finish for general-purpose use across common workpiece materials
• 0.515-inch square drive fits standard tap wrenches and holders

Compatibility

Designed as a standard replacement or addition for 1/2-14 NPS pipe tapping applications in plumbing, HVAC, and general industrial maintenance work.

Installation Notes

Pipe taps are installed by licensed plumbers, pipefitters, and qualified maintenance technicians. Before tapping, ensure the workpiece is securely fixtured and the correct pilot hole size is drilled per NPS thread specifications. Apply an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Use steady, controlled torque and back off periodically to break chips and prevent tap breakage.
