Hertel G127383-S Pipe Tap 3/8-18 Nptf 4 Flute Hss

Product Description

The HERTEL G127383-S is a standard pipe tap designed to cut NPTF (National Pipe Taper Fuel) threads in metal pipe fittings, manifolds, and threaded ports. Built from high speed steel with a bright uncoated finish, this tap threads 3/8-18 tapered pipe connections in a single pass. The 4-flute geometry provides balanced cutting action and helps clear chips during the tapping operation. Overall length is 2-9/16 inches. This tool is used by plumbers, pipefitters, HVAC technicians, and machinists working with threaded pipe assemblies in fuel, hydraulic, and pneumatic systems.

This tap is suited for production and maintenance applications where NPTF pipe thread connections are required. NPTF threads form a pressure-tight seal on assembly without the need for sealant, making this tap a common choice for hydraulic fittings, fuel line ports, and pneumatic manifolds. The 3/8-18 size fits standard 3/8-inch pipe thread applications found across residential and commercial plumbing, HVAC equipment housings, and industrial piping systems.

Key Features

• Thread standard: NPTF for pressure-tight tapered pipe connections
• Thread size: 3/8-18 (3/8-inch pipe diameter, 18 threads per inch)
• 4-flute design for balanced cutting and chip evacuation
• High speed steel construction for durability across a range of metal workpieces
• Bright/uncoated finish suitable for general-purpose tapping applications
• Overall length of 2-9/16 inches for use in standard tap handles and machines

Compatibility

Designed for use in any application requiring NPTF tapered pipe threads at the 3/8-18 size, including threaded ports in metal fittings, valve bodies, and equipment housings.

Installation Notes

This tap is installed by licensed pipefitters, machinists, and HVAC technicians using a standard tap handle or tapping machine. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping to prevent misalignment. Follow applicable trade and safety codes when working on pressurized pipe systems.
