Value Collection MSC-04668091 Pipe Tap 1-11/2 Nptf Hss

Product Description

The VALUE COLLECTION MSC-04668091 is a standard pipe tap designed to cut National Pipe Taper Fuel (NPTF) threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap produces a 1-11/2 NPTF thread profile across a 1-3/4 inch thread length. The 5-flute design distributes cutting load evenly, which reduces chatter and improves thread finish in harder materials. With a shank diameter of 1.125 inches and a square drive size of 0.843 inches, this tap is sized for use in standard tap wrenches or machine setups. Plumbers, pipefitters, and machinists working on fuel or fluid systems will find this tool suitable for tapping large-diameter pipe thread connections.

This pipe tap is used to create NPTF internal pipe threads in ferrous and non-ferrous metals. NPTF threads are commonly found in hydraulic fittings, fuel line connections, and pressure plumbing applications where a dry, pressure-tight seal is required without sealant. The 1-11/2 thread size is a large-diameter specification suited for industrial piping, manifolds, and heavy-duty fluid system components. It is appropriate for both hand tapping and machine tapping in production or maintenance environments.

Key Features

• NPTF thread standard ensures dry-seal compatibility for pressure-tight connections
• High-speed steel construction provides durability and heat resistance during cutting
• 5-flute design reduces cutting load and improves thread finish
• Bright, uncoated finish suitable for general-purpose tapping in a range of metals
• 1-3/4 inch thread length accommodates typical pipe wall thicknesses
• Square drive size of 0.843 inches fits standard tap wrenches and machine holders

Compatibility

Designed for use in any application requiring a 1-11/2 NPTF internal pipe thread, including industrial piping, hydraulic systems, and fuel line fittings in metal workpieces.

Installation Notes

This tap is installed by licensed pipefitters, machinists, or qualified tradespeople using a tap wrench or machine tapping setup. Always secure the workpiece firmly and apply appropriate cutting fluid to extend tap life and improve thread quality. Back the tap out periodically to clear chips and prevent binding, especially in deeper cuts. Follow applicable IFGC or IPC requirements when tapping threads for gas or plumbing system connections.
