Value Collection MSC-04668018 Pipe Tap 1/16-27 Nptf

Product Description

The VALUE COLLECTION MSC-04668018 is a standard pipe tap designed to cut internal NPTF threads in metal workpieces. It produces a 1/16-27 thread profile conforming to the National Pipe Taper Fuel standard, which creates a pressure-tight mechanical seal without requiring a separate sealant compound. Constructed from high-speed steel with a bright, uncoated finish, this tap offers the hardness and edge retention needed for threading ferrous and non-ferrous materials. The 4-flute configuration supports chip evacuation during through-hole and short blind-hole applications. Thread length is 11/16 inches, with a shank diameter of 0.3125 inches and a square drive size of 0.2340 inches for standard tap wrench or holder engagement. Machinists, pipefitters, and maintenance technicians use this tool in production and repair settings.

This tap is suited for creating NPTF pipe threads in hydraulic fittings, pneumatic ports, fuel system components, and fluid transfer assemblies where a dry, leak-free connection is required. The 1/16-27 size is commonly used in small-bore applications such as pressure gauge ports, sensor bungs, and instrument connections found in residential and commercial plumbing, HVAC, and light industrial equipment. It is appropriate for hand tapping with a tap wrench or machine tapping in a drill press or CNC setup when using appropriate feed rates and cutting fluid.

Key Features

• 1/16-27 NPTF thread form for pressure-tight, dry-seal pipe connections
• High-speed steel construction provides hardness and wear resistance for ferrous and non-ferrous materials
• 4 flutes promote chip clearance during cutting
• Bright, uncoated finish suitable for general-purpose threading applications
• 11/16 inch thread length accommodates standard small-bore pipe thread engagement
• 0.3125 inch shank diameter fits standard tap holders and wrenches

Compatibility

Designed as a standard replacement or general-use pipe tap for creating 1/16-27 NPTF internal threads; compatible with tap wrenches and machine tap holders accepting a 0.3125 inch shank diameter.

Installation Notes

This tap is installed by machinists, pipefitters, or maintenance technicians using a tap wrench or powered tapping fixture. Always use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and align the tap perpendicular to the drilled hole to prevent tap breakage. Do not force the tap if resistance increases suddenly, as pipe taps are tapered and bind quickly if misaligned or bottomed out.
