Hertel R127097T-S 1/8-27 Npt Pipe Tap 5 Flute Tin Hss

Product Description

The HERTEL R127097T-S is a 1/8-27 NPT interrupted thread pipe tap manufactured from high speed steel with a titanium nitride (TiN) coating. It is designed to cut tapered pipe threads in ferrous and non-ferrous metals, producing threads that seal with standard NPT fittings used in plumbing, HVAC, and gas line assemblies. The 5-flute design with a regular hook geometry provides controlled cutting action and chip evacuation. The interrupted thread configuration reduces cutting forces and heat buildup during tapping operations. At 2.125 inches overall length, it fits standard tap wrenches and machine tool holders used in the trade.

This tap is suited for threading pipe entry points in manifolds, valve bodies, fittings, and equipment housings where 1/8-27 NPT connections are required. It is commonly used by plumbers, pipefitters, HVAC technicians, and machinists when fabricating or repairing threaded ports in metal assemblies. The NPT taper standard ensures compatibility with standard pipe fittings and sealant-thread joints across residential and commercial mechanical systems.

Key Features

• 1/8-27 NPT thread form for standard tapered pipe thread applications
• 5-flute interrupted thread design reduces cutting forces and heat during tapping
• TiN coating improves surface hardness and extends tool life in ferrous materials
• High speed steel construction provides toughness across a wide range of workpiece materials
• Regular hook geometry for controlled chip formation in typical shop and field conditions
• 2.125 inches overall length compatible with standard tap wrenches and machine holders

Compatibility

Designed for cutting 1/8-27 NPT tapered pipe threads in metal workpieces. Fits standard tap wrenches and machine tool holders accepting straight-shank pipe taps of this size.

Installation Notes

This tap should be installed and operated by qualified machinists, pipefitters, or mechanical tradespeople familiar with hand and machine tapping procedures. Use appropriate cutting fluid for the workpiece material to reduce friction and extend tool life. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the drilled hole before beginning the threading operation. Follow applicable shop safety practices and relevant code requirements for the system being threaded.
