Hertel G127061T-S Pipe Tap 1/8-27 Nptf 4 Flute Hss Tin

Product Description

The HERTEL G127061T-S is a standard pipe tap designed to cut 1/8-27 NPTF threads in metal workpieces. Built from high speed steel with a titanium nitride (TiN) coating, it delivers the hardness and wear resistance required for threading pipe fittings, valve bodies, and manifold ports. The 4-flute configuration provides stable cutting action and efficient chip evacuation during through and blind hole tapping. Overall length is 2.125 inches. This tap is suited for use in plumbing, HVAC, and industrial pipe fitting applications where a pressure-tight NPTF thread form is required.

This tap is used when threading ports or connections to accept 1/8-inch NPT fittings, a size commonly found in pressure gauges, sensor ports, drain plugs, and instrumentation fittings. Typical applications include threading steel, iron, brass, and aluminum components in plumbing, HVAC refrigerant line assemblies, compressed air systems, and hydraulic manifolds. It is intended for use by machinists, pipefitters, plumbers, and HVAC technicians performing field or shop fabrication work.

Key Features

• 1/8-27 NPTF thread form produces a pressure-tight, dryseal pipe thread
• High speed steel construction provides durability across a range of metals
• TiN coating reduces friction and extends cutting tool life
• 4-flute design promotes chip evacuation and thread accuracy
• 2.125-inch overall length suits standard tapping handles and machines

Compatibility

Designed for use in any application requiring a 1/8-27 NPTF dryseal pipe thread, including steel, cast iron, brass, and aluminum workpieces in plumbing, HVAC, and industrial piping systems.

Installation Notes

Use appropriate cutting fluid or tapping oil to reduce heat and extend tool life, especially when threading steel or iron. Secure the workpiece fully before tapping and ensure the tap is started square to the hole to avoid cross-threading. NPTF threads are tapered and self-sealing by design; do not over-tap or force the tap beyond the thread engagement depth required for the fitting. This work is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable IPC and IFGC standards.
