Value Collection 20649 Standard Pipe Tap 1/16-27 Npt

Product Description

The VALUE COLLECTION 20649 is a standard NPT pipe tap designed for cutting 1/16-27 tapered pipe threads in metal workpieces. Built from high-speed steel (HSS) with an oxide gold finish, this tap offers the wear resistance and edge retention needed for threading operations in pipe fitting and plumbing fabrication work. The 4-flute design promotes efficient chip evacuation and consistent thread form. With a thread length of 0.6875 inches and a shank diameter of 0.3125 inches, this tap is sized for use in standard tap wrenches and machine setups. It is suited for machinists, pipefitters, and plumbers who need to cut NPT internal threads in fittings, manifolds, or custom pipe connections.

This tap is used wherever a 1/16-27 NPT internal thread must be cut from scratch or restored in a workpiece. Typical applications include tapping ports in hydraulic manifolds, HVAC fittings, instrumentation ports, and small-diameter pipe connections. The NPT taper thread standard ensures a pressure-bearing, leak-resistant joint when paired with a properly sized pipe nipple or fitting. This tool is appropriate for both shop-floor machining environments and field repair work where a hand tap wrench is used.

Key Features

• 1/16-27 NPT thread form for tapered pipe thread applications
• High-speed steel construction provides hardness and edge retention across a range of workpiece materials
• Oxide gold finish improves lubricity and reduces friction during the cutting process
• 4-flute configuration supports chip evacuation and consistent thread geometry
• Shank diameter of 0.3125 inches fits standard tap wrench and machine collet sizes
• Regular hook geometry for general-purpose threading in through and blind holes

Compatibility

Designed as an OEM-style replacement or general-purpose tool for cutting 1/16-27 NPT internal pipe threads in metal fittings, manifolds, and pipe components across plumbing, HVAC, and instrumentation applications.

Installation Notes

Installation of this tap should be performed by a qualified machinist, pipefitter, or plumber familiar with thread-cutting procedures. Always use an appropriate cutting fluid or tapping oil to extend tool life and improve thread quality. Ensure the workpiece is securely clamped and the tap is started perpendicular to the drilled hole to avoid cross-threading or tap breakage. Follow applicable codes and safety practices when working with tapping equipment.
