Eagle Cutting Tool PT-40000-8-I Hss Npt Pipe Tap

Product Description

The EAGLE CUTTING TOOL PT-40000-8-I is a high-speed steel (HSS) NPT pipe tap designed to cut tapered pipe threads in ferrous and non-ferrous materials. Sized for 4-8 NPT threads, this tap produces the tapered thread form required for pressure-tight pipe connections in plumbing, HVAC, and mechanical piping systems. The HSS construction provides the hardness and wear resistance needed for clean thread cutting in production or field service conditions. Plumbers, pipefitters, and HVAC technicians reach for this tap when threading pipe ports, fittings, or threaded bosses to NPT standard. At 0.09 pounds, it is a compact, lightweight tool suited for both bench use and portable jobsite work.

This pipe tap is appropriate for use in residential and commercial applications wherever NPT-threaded connections are required. Common uses include tapping threaded ports in pipe flanges, valve bodies, manifolds, and equipment housings. It is well suited for service and repair scenarios where a pre-threaded fitting is not available or where a custom port must be cut in the field or shop.

Key Features

• HSS construction provides durability and wear resistance for threading steel, iron, brass, and similar materials
• 4-8 NPT thread size for tapered pipe thread applications requiring pressure-tight joints
• Tapered NPT profile meets ANSI pipe thread standards for compatibility with standard NPT fittings
• Lightweight at 0.09 pounds, easy to handle in tight or overhead installations
• Import grade suitable for general-purpose threading tasks in trade and maintenance settings

Compatibility

Designed as a general-purpose replacement or supplemental tap for use in any application requiring 4-8 NPT tapered pipe threads per ANSI standard.

Installation Notes

This tap is installed using a standard tap wrench or appropriate tap driver. Always use cutting fluid when tapping to reduce heat buildup and extend tool life. Ensure the workpiece is securely clamped before beginning the threading operation. Follow applicable safety practices for cutting tool use, including eye protection and proper chip clearance.
