Value Collection MSC-04668042 Pipe Tap 3/8-18 Nptf Hss

Product Description

The VALUE COLLECTION MSC-04668042 is a standard pipe tap designed to cut National Pipe Taper Fuel (NPTF) threads in a 3/8-18 thread size. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent thread-cutting performance in metal pipe fittings and threaded connections. The 4-flute geometry provides balanced chip evacuation and cutting stability during tapping operations. With a thread length of 1-1/16 inches, it accommodates standard pipe thread depth requirements. This tap is a go-to tool for plumbers, pipefitters, and mechanical technicians who need reliable NPTF threads for pressure-tight connections in fuel, hydraulic, or pneumatic systems.

This tap is suited for use in shop and field environments where NPTF pipe threads must be cut into ferrous or non-ferrous materials. It handles typical applications including pipe fitting assemblies, manifold ports, and hydraulic block work where tapered thread sealing is required. The NPTF standard ensures threads that seal on the thread form itself, making it appropriate for fluid and gas systems where thread-compound-only seals are insufficient. It is installed by licensed plumbers, pipefitters, and industrial maintenance technicians working to IFGC, IPC, or shop-standard specifications.

Key Features

• 3/8-18 NPTF thread form cuts pressure-tight tapered pipe threads without relying solely on sealant
• High-speed steel construction provides heat and wear resistance during hand or machine tapping
• 4-flute design promotes even cutting load distribution and reliable chip clearance
• Bright uncoated finish maintains dimensional accuracy and works with standard cutting fluids
• 1-1/16 inch thread length accommodates standard pipe thread engagement depth
• Shank diameter of 0.7 inches and square size of 0.531 inches fit standard tap wrenches and machine holders

Compatibility

Designed as a standard NPTF pipe tap for use wherever 3/8-18 tapered pipe threads are required in ferrous and non-ferrous materials.

Installation Notes

Pipe taps of this type are used by licensed plumbers, pipefitters, and mechanical technicians. Always secure the workpiece firmly before tapping and use an appropriate cutting fluid to extend tap life and improve thread finish. Back the tap out periodically to clear chips and prevent binding, especially in blind holes. Ensure the tapping tool is properly aligned to avoid thread distortion or tap breakage.
