Value Collection MSC-04668117 Pipe Tap 1-1/2 11-1/2 Nptf Hss

Product Description

The VALUE COLLECTION MSC-04668117 is a standard pipe tap designed to cut National Pipe Taper Fuel (NPTF) threads in metal workpieces. Built from high-speed steel with a bright, uncoated finish, this tap produces a 1-1/2 - 11-1/2 NPTF thread profile across a 1.75-inch thread length. The 7-flute design provides additional cutting edges compared to standard 4- or 5-flute taps, which helps distribute cutting load and improve chip evacuation in tougher materials. It carries a 1.5-inch shank diameter and a 1.125-inch square drive size. Plumbers, pipefitters, and machinists use this tap when threading pipe ports or fittings that require a pressure-tight, dry-seal connection without sealant.

This tap is suited for threading pipe connections in plumbing, HVAC, hydraulic, and industrial piping applications where NPTF dry-seal standards are required. The 1-1/2 - 11-1/2 size corresponds to 1.5-inch nominal pipe diameter, making it appropriate for larger-diameter piping systems found in commercial and light industrial installations. It is typically used in a drill press, tapping machine, or heavy-duty hand tapping setup with appropriate cutting fluid for the workpiece material.

Key Features

• NPTF thread profile produces a pressure-tight dry-seal connection without requiring thread sealant
• 7-flute configuration distributes cutting load and aids chip evacuation
• High-speed steel construction withstands heat generated during tapping of ferrous and non-ferrous metals
• Bright, uncoated finish suitable for use with cutting fluids across a range of materials
• 1.125-inch square drive size compatible with standard tap wrenches and machine adapters
• Thread length of 1.75 inches provides sufficient engagement depth for full-form NPTF threads

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring a 1-1/2 - 11-1/2 NPTF pipe tap in high-speed steel.

Installation Notes

Installation should be performed by a qualified pipefitter, machinist, or plumber familiar with pipe tapping procedures. Always secure the workpiece and ensure the tap is started square to the hole before applying cutting pressure. Use an appropriate cutting fluid or tapping compound for the material being threaded to extend tool life and improve thread quality. Follow applicable codes such as IFGC or IPC when threading connections in gas or potable water systems.
