Value Collection JY4350047 Pipe Tap 3/8-18 Npt

Product Description

The VALUE COLLECTION JY4350047 is a standard pipe tap designed to cut internal NPT-tapered threads in pipe fittings, valves, and threaded port applications. Sized for the 3/8-18 NPT thread standard, it cuts a tapered thread profile that forms a pressure-tight seal when assembled with mating fittings. The tap features 4 flutes ground from carbon steel with a bright, uncoated finish. Thread length is 1-1/16 inches, providing sufficient depth for standard pipe thread engagement. Plumbers, pipefitters, and HVAC service technicians use this tap to chase damaged threads or cut fresh threads in ductile iron, mild steel, aluminum, and similar materials.

This pipe tap is suited for residential and light commercial plumbing, gas line fittings, hydraulic manifolds, and HVAC refrigerant circuit components that use NPT threaded ports. It is appropriate for bench work or field use in applications requiring a clean, full-form 3/8-18 NPT thread. The 4-flute design provides good chip clearance and thread finish across most common pipe materials encountered in trade service work.

Key Features

• 3/8-18 NPT tapered thread form for pressure-tight pipe connections
• 4 flutes for effective chip evacuation during threading
• Carbon steel construction suitable for threading mild steel, aluminum, and ductile iron
• Bright, uncoated finish for visual thread inspection after cutting
• 1-1/16 inch thread length for full NPT thread engagement depth
• Shank diameter of 0.700 inches and square drive size of 0.531 inches for standard tap wrench compatibility

Compatibility

Designed as a standard replacement or service tap for any application requiring a 3/8-18 NPT internal thread, including pipe fittings, valve bodies, manifolds, and threaded port components across plumbing, HVAC, and gas piping systems.

Installation Notes

This tap should be installed using a properly sized tap wrench that accepts a 0.531-inch square drive. Shut off and depressurize any line or fitting being rethreaded before beginning work. Apply an appropriate cutting fluid for the material being threaded to extend tap life and improve thread finish. NPT pipe threads are tapered and must be cut to the correct depth to achieve a pressure-tight assembly — follow applicable IPC or IFGC guidelines for thread engagement requirements.
