Value Collection MSC-04662102 Npt Pipe Tap 1-1/4 11-1/2

Product Description

The VALUE COLLECTION MSC-04662102 is a standard NPT pipe tap designed to cut internal tapered pipe threads in metal pipe fittings, valve bodies, and threaded ports. Sized for 1-1/4 inch to 11-1/2 TPI NPT thread form, this tap produces the tapered thread profile required for pressure-rated pipe connections. It is constructed from high-speed steel with a bright uncoated finish, suited for general-purpose tapping in steel, cast iron, and similar ferrous materials. With 5 flutes and a regular hook geometry, it clears chips effectively in through-hole and short blind-hole applications. A licensed pipefitter, plumber, or machinist performs this type of work on fluid and gas piping systems.

This tap is used in residential and commercial plumbing, HVAC piping, and industrial fluid systems wherever a 1-1/4 inch NPT threaded port must be cut or chased. Typical applications include tapping threaded inlets in manifolds, pipe flanges, valve bodies, and equipment housings. It is appropriate for use in pipe fabrication shops and field service settings where NPT-threaded fittings must seal under pressure.

Key Features

• 1-1/4 inch to 11-1/2 TPI NPT thread form for standard tapered pipe thread cutting
• High-speed steel construction for durability in ferrous metal tapping
• 5-flute, regular hook geometry for effective chip evacuation
• Bright uncoated finish for general-purpose service
• 1-3/4 inch thread length provides adequate engagement depth for pipe thread tapping
• 4 inch overall length compatible with standard tap handles and machine holders

Compatibility

Designed as a standard replacement or general-use NPT pipe tap for applications requiring 1-1/4 inch to 11-1/2 TPI tapered pipe threads per NPT standards.

Installation Notes

Pipe tap work should be performed by a licensed plumber, pipefitter, or qualified machinist. Always secure the workpiece and apply appropriate cutting fluid to extend tap life and improve thread quality. Use a calibrated tap handle or machine tapping setup to maintain axial alignment and prevent tap breakage. Verify thread fit with a GO/NO-GO gauge before pressurizing any connection.
