Hertel G127360C-S 3/8-18 Npt Pipe Tap 4 Flute Hss Ticn

Product Description

The HERTEL G127360C-S is a standard pipe tap designed to cut 3/8-18 NPT internal threads in metal workpieces. It is manufactured from high speed steel and carries a TiCN (titanium carbonitride) coating that increases surface hardness and reduces friction during cutting. The tap features 4 flutes with a regular hook angle and measures 2.5625 inches overall length. This tool is used by pipefitters, plumbers, and machinists to create tapered pipe threads that meet NPT standards for pressure-rated connections in fluid and gas systems.

This tap is suited for threading operations in pipe fittings, valve bodies, manifolds, and similar components where NPT-standard tapered threads are required. It is appropriate for use in both production shop environments and field service applications. The TiCN finish extends tool life compared to uncoated HSS taps, making it a practical choice for repetitive threading jobs in steel, cast iron, and similar ferrous materials.

Key Features

• 3/8-18 NPT thread form for standard tapered pipe thread applications
• High speed steel construction provides toughness and wear resistance
• TiCN coating increases hardness and reduces built-up edge during cutting
• 4-flute design with regular hook for controlled chip evacuation
• 2.5625 inch overall length fits standard tap handles and machine spindles

Compatibility

Designed for cutting 3/8-18 NPT internal tapered pipe threads in ferrous and compatible non-ferrous workpieces using standard tap handles or tapping machines.

Installation Notes

This tap is installed by licensed machinists, pipefitters, or plumbers using a standard tap wrench or machine tapping setup. Secure the workpiece firmly before beginning the tapping operation, and apply an appropriate cutting fluid to reduce heat and extend tool life. Follow ANSI and applicable trade standards for thread depth and engagement requirements. Inspect the tap for wear or chipping before each use and replace if cutting edge integrity is compromised.
