Balax 02500-000 Thread Forming Pipe Tap 1/2-14 Npt Hss

Product Description

The BALAX 02500-000 is a thread forming pipe tap designed to cut NPT-standard internal pipe threads without producing chips. Built from high-speed steel with a bright finish, this tap cold-forms 1/2-14 NPT threads by displacing material rather than cutting it, resulting in stronger thread walls and no swarf to clear from the bore. Overall length is 3.125 inches with a thread length of 1.375 inches and a shank diameter of 0.187 inches. The 0.515-inch square drive and 0.625-inch square length suit standard tap wrenches and machine holders. This tool is intended for machinists, pipefitters, and plumbers working with ductile materials in production or field applications.

The 02500-000 is rated for use in aluminum and copper, where thread forming delivers cleaner results than cutting taps. Typical applications include threading pipe ports in fittings, manifolds, valves, and housings that require a leak-resistant NPT seal. The BXPT series is built for both hand tapping and machine tapping operations where chip-free threading is required. The 14 threads-per-inch NPT profile conforms to standard tapered pipe thread geometry for reliable sealing in fluid and gas systems.

Key Features

• Thread forming design displaces material rather than cutting, producing stronger threads with no chips
• 1/2-14 NPT thread profile for standard tapered pipe thread connections
• High-speed steel construction for durability in aluminum and copper applications
• Bright finish provides a smooth surface suitable for use with cutting fluids
• 3.125-inch overall length with 1.375-inch thread length for access in typical port depths
• BXPT series with 0.515-inch square drive compatible with standard tap wrenches and holders

Compatibility

Rated for use in aluminum and copper workpieces. Designed to produce 1/2-14 NPT tapered internal pipe threads per standard NPT thread geometry.

Installation Notes

Thread forming taps require a properly sized form tap drill - consult BALAX or NPT thread forming drill charts for the correct hole size before tapping. Secure the workpiece and align the tap perpendicular to the bore before applying torque. Apply an appropriate cutting or tapping fluid for the base material to reduce friction and extend tool life. This tap is intended for use by qualified machinists or trade professionals familiar with NPT thread requirements.
