Value Collection JY4350021 Pipe Tap 1/8-27 Npt 4 Flute

Product Description

The VALUE COLLECTION JY4350021 is a standard pipe tap designed to cut internal NPT (National Pipe Taper) threads in metal workpieces. Sized at 1/8-27 NPT, it produces tapered threads that form a pressure-tight seal when mated with standard NPT fittings, making it a go-to tool in plumbing, HVAC, and mechanical piping work. The tap is machined from carbon steel with a bright uncoated finish and features 4 flutes for efficient chip evacuation during cutting. The threaded cutting length is 0.75 inches, and the shank diameter is 0.4375 inches with a 0.3280-inch square drive for use in a standard tap wrench or machine chuck.

This tap is suited for threading pipe ports, fittings, manifolds, and housings where 1/8-27 NPT connections are required. Typical applications include tapping sensor ports on HVAC equipment, threading ports in hydraulic or pneumatic manifolds, and creating NPT entry points in steel or similar workpieces during plumbing rough-in or equipment fabrication. It is commonly used by licensed plumbers, HVAC technicians, pipefitters, and machinists working in both residential and light commercial settings.

Key Features

• 1/8-27 NPT taper thread form produces pressure-tight pipe thread connections
• 4-flute design promotes chip removal and clean thread formation
• Carbon steel construction provides adequate hardness for threading mild steel, cast iron, and soft alloys
• Bright uncoated finish allows easy visual inspection of cutting edges before and after use
• 0.75-inch thread length suits standard pipe port depths
• 0.4375-inch shank with 0.3280-inch square drive is compatible with standard tap wrenches and machine holders

Compatibility

Designed for use wherever a 1/8-27 NPT internal thread is required in ferrous and non-ferrous workpieces. Fits standard tap wrenches and machine setups accepting a 0.4375-inch shank with a 0.3280-inch square drive.

Installation Notes

Secure the workpiece before tapping and use a properly sized tap wrench or tapping machine to maintain alignment with the pilot hole. Apply a suitable cutting fluid to reduce heat and extend tap life, especially when threading steel. Back the tap off periodically to break chips and prevent binding. Follow applicable shop safety practices and verify pilot hole diameter against NPT tap drill charts before starting.
