Value Collection MSC-04668026 Pipe Tap 1/8-27 Nptf 4 Flute Hss

Product Description

The VALUE COLLECTION MSC-04668026 is a standard pipe tap designed to cut 1/8-27 NPTF (National Pipe Taper Fuel) internal threads in metal workpieces. With 4 flutes and a regular hook geometry, this tap produces a pressure-tight, tapered thread form suited for pipe fittings, fluid line connections, and pneumatic or hydraulic ports. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it handles a broad range of ferrous and non-ferrous materials in production and maintenance applications. Machinists and pipefitters reach for this tap when threading ports in housings, manifolds, or fittings where a reliable NPTF seal is required.

This tap is appropriate for threading applications in HVAC, plumbing, and fluid-power environments where 1/8-27 NPTF ports are common. It covers both shop and field work, including tapping ports in valve bodies, compressor housings, pressure gauge connections, and instrumentation fittings. The 3/4 inch thread length provides sufficient engagement depth for standard 1/8-27 NPTF connections. Suitable for use in manual tap handles, T-handle wrenches, or machine tapping on bench drill presses and CNC equipment at appropriate low speeds.

Key Features

• 1/8-27 NPTF thread form cuts pressure-tight tapered pipe threads without sealant when properly formed
• 4-flute design balances chip clearance and thread finish across common workpiece materials
• High-speed steel construction provides durability and re-sharpening potential in production use
• Bright uncoated finish allows clear visual inspection of cutting edges before and after use
• 3/4 inch thread length suits standard port depth requirements for 1/8-27 NPTF connections
• Regular hook geometry is compatible with standard tap handles and machine tapping setups

Compatibility

Designed as a standard replacement or service tap for any application requiring 1/8-27 NPTF internal threads; fits standard tap wrenches and holders sized for a 0.4375 inch shank diameter.

Installation Notes

This tap is installed by machinists or pipefitters using a calibrated tap handle or machine tapping setup. Always drill the correct tap drill size before tapping and use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Back the tap out periodically to clear chips, particularly in blind holes. Inspect cutting edges for wear or chipping before each use to avoid thread damage or tap breakage.
