Value Collection JY4350039 1/4-18 Npt Pipe Tap 4 Flute

Product Description

The VALUE COLLECTION JY4350039 is a standard pipe tap designed to cut 1/4-18 NPT internal threads in pipe fittings, valve bodies, manifolds, and similar plumbing or HVAC components. Manufactured from carbon steel with a bright, uncoated finish, this tap features 4 flutes and a regular hook geometry that clears chips efficiently during hand or machine tapping. The 1-1/16 inch thread length provides adequate engagement for cutting full-form NPT tapered threads. Plumbers, pipefitters, HVAC technicians, and machinists use this tap when threading new holes or chasing damaged threads in ferrous and non-ferrous workpieces.

This pipe tap is suited for residential and light commercial applications where 1/4-18 NPT threaded connections are standard. Common uses include tapping ports in copper and steel pipe assemblies, HVAC line sets, refrigerant service ports, gas appliance fittings, and pressure gauge connections. The NPT taper profile ensures a pressure-tight seal when mated threads are properly applied with thread sealant or tape.

Key Features

• 1/4-18 NPT thread size for standard tapered pipe thread cutting
• 4-flute design promotes efficient chip evacuation during tapping
• Carbon steel construction provides adequate hardness for threading ferrous and non-ferrous materials
• Bright, uncoated finish allows easy visual inspection of cutting edge condition

• Regular hook geometry suitable for hand tapping and light machine tapping operations

Compatibility

Designed as an OEM-style pipe tap for any application requiring 1/4-18 NPT internal threads in pipe fittings, valve bodies, or ported components across plumbing, HVAC, and gas piping systems.

Installation Notes

This tap is installed by a plumber, pipefitter, or HVAC technician using a standard tap wrench or appropriate machine holder. Always isolate and depressurize the system before tapping any pipe or fitting that will carry gas, refrigerant, or pressurized fluid. Use cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Follow applicable codes such as IFGC or IPC for thread engagement requirements on gas and water piping connections.
