Value Collection MSC-04668059 Pipe Tap 1/2-14 Nptf Hss

Product Description

The VALUE COLLECTION MSC-04668059 is a standard pipe tap designed to cut internal NPTF-threaded connections in metal pipe fittings, manifolds, and ported components. It produces a 1/2-14 NPTF thread profile, which provides a pressure-tight mechanical seal without requiring a separate sealant in many dry-seal applications. Machined from high-speed steel (HSS), it holds cutting-edge integrity across a wide range of ferrous and non-ferrous materials. The bright, uncoated finish means no coating buildup to affect thread tolerance. With 4 flutes and a regular hook geometry, this tap delivers reliable chip evacuation during through-hole and blind-hole tapping operations.

This pipe tap is suited for plumbing, HVAC, and mechanical service work wherever NPTF internal threads must be cut or chased in metal. Common applications include tapping ports in manifolds, valve bodies, compressor housings, and hydraulic fittings. It is appropriate for use with a standard tap wrench, machine tapping setup, or drill press with appropriate tapping attachment. The 1-3/8 inch thread length accommodates typical pipe wall and fitting boss depths encountered in trade service work.

Key Features

• 1/2-14 NPTF thread form for dry-seal pressure-tight connections
• High-speed steel construction maintains edge hardness under heat and cutting load
• 4-flute regular hook geometry promotes controlled chip removal
• Bright uncoated finish preserves dimensional accuracy without coating interference
• 1-3/8 inch thread length suits standard pipe fitting boss depths
• 0.6875-inch shank diameter fits compatible tap chucks and wrenches

Compatibility

Designed for cutting or chasing 1/2-14 NPTF internal threads in metal workpieces including pipe fittings, valve bodies, manifolds, and ported housings where a dry-seal tapered pipe thread is required.

Installation Notes

This tap should be installed and operated by a qualified machinist, pipefitter, or HVAC-refrigeration technician familiar with tapping procedures. Always ensure the workpiece is securely fixtured and the correct cutting fluid is applied for the base material before tapping. Use a calibrated torque-limiting tap wrench or machine tapper to avoid tap breakage in harder materials. Back the tap off periodically to break and clear chips, particularly in blind-hole applications.
