Value Collection 20602 Pipe Tap 3/8-18 Nps 4 Flute Hss

Product Description

The VALUE COLLECTION 20602 is a standard pipe tap designed to cut internal NPS (National Pipe Straight) threads in pipe fittings, valves, and related components. Built from high-speed steel with an oxide gold finish, this tap offers solid wear resistance for threading operations in metal workpieces. It cuts a 3/8-18 thread profile across a 1-1/16 inch thread length, with a 4-flute design that clears chips efficiently during hand or machine tapping. Plumbers, pipefitters, and maintenance technicians reach for this tap when threading pipe ports, bosses, or fittings to NPS standards. The shank diameter measures 0.700 inches and the square drive measures 0.531 inches.

This tap is suited for threading operations in plumbing, HVAC, and industrial piping applications where NPS thread form is required. It is appropriate for use in ferrous and non-ferrous metals when tapping pipe-thread ports in flanges, manifolds, valve bodies, and similar components. The 3/8-18 size is a common thread specification in residential and light commercial plumbing and gas piping systems. Technicians typically use this tap in a tap handle or machine tap holder for controlled threading.

Key Features

• 3/8-18 NPS thread form for standard pipe threading applications
• High-speed steel construction for durability in metal tapping operations
• Oxide gold finish improves lubricity and surface hardness
• 4-flute design promotes efficient chip evacuation
• 1-1/16 inch thread length provides adequate engagement depth for pipe ports
• Regular hook geometry suitable for general-purpose tapping

Compatibility

Designed for cutting NPS internal pipe threads in metal workpieces. Appropriate for plumbing, pipefitting, and mechanical applications requiring a 3/8-18 NPS thread profile.

Installation Notes

This tap is installed by a plumber, pipefitter, or machinist using a standard tap handle or machine tap holder sized to the 0.531 inch square drive. Always apply cutting fluid during tapping to reduce heat and extend tool life. Secure the workpiece before tapping to prevent movement and thread misalignment. Follow applicable code requirements for thread form and engagement depth on pressure-bearing pipe connections.
