Irwin IR1907ZR Npt Pipe Tap 1 Inch

Product Description

The IRWIN IR1907ZR is a 1-inch NPT pipe tap designed for cutting internal tapered pipe threads in metal workpieces. NPT (National Pipe Taper) threads follow a standardized taper profile, making them the standard thread form for pressure-tight connections in plumbing, HVAC piping, and industrial fluid systems. This tap is used by pipefitters, plumbers, and machinists to create threaded ports in fittings, manifolds, pipe flanges, and similar components. It is sold individually and suited for shop or field threading work where a properly sized tapped hole is required before installing a threaded pipe fitting.

This tap is appropriate for metalworking applications where a 1-inch NPT female thread is needed. Common use cases include tapping ports in steel or iron pipe fittings, valve bodies, pump housings, and fabricated pipe assemblies in residential and commercial mechanical systems. It is a standard tool in any pipefitting or plumbing trade shop handling ferrous and non-ferrous pipe work.

Installation Notes

This tap is installed using a tap wrench or appropriate machine tapping setup; ensure the workpiece is securely clamped before threading. Apply cutting oil throughout the tapping process to reduce heat and extend tap life. Follow applicable trade and facility safety practices when operating cutting tools. Always verify the drilled hole size matches the correct tap drill specification for 1-inch NPT before tapping.
