Extension Pipe Taps

WESTport manufactures Special Extension Pipe Taps for customers who require precision pipe threads in locations where standard pipe taps cannot provide adequate reach. Featuring an extended shank and overall length, these custom tools are engineered for deep-hole threading, recessed ports, valve bodies, hydraulic manifolds, and other components where access is limited. By extending the cutting portion of the tool beyond the workholding fixture or surrounding features, Extension Pipe Taps improve machining accessibility while maintaining accurate thread geometry and exceptional cutting performance.

As part of WESTport's Special Taps product line, every Extension Pipe Tap is manufactured to your exact specifications. Whether your application requires NPT, NPTF, BSPT, BSPP, ANPT, NPSM, or another specialty pipe thread, our engineering team can produce tooling that matches your blueprint, sample part, or technical drawing. Custom diameters, thread lengths, chamfers, shank dimensions, square sizes, and overall lengths are available to ensure optimum performance in your specific machining process.

Every WESTport Extension Pipe Tap is precision manufactured from premium High-Speed Steel (HSS), cobalt, powdered metal, or carbide, depending on the workpiece material and production requirements. Precision-ground cutting geometry produces accurate pipe threads with excellent surface finish and repeatability, while optional premium coatings help reduce friction, improve wear resistance, and extend tool life in demanding production environments.

Extension Pipe Taps are widely used in industries where threaded pipe connections must be produced in deep or difficult-to-access components. Manufacturers of hydraulic systems, pneumatic equipment, oil and gas components, pumps, valves, pressure vessels, industrial machinery, and process equipment rely on long-reach pipe taps to produce consistent, leak-resistant threaded connections without compromising machining accuracy. WESTport's custom engineering capabilities allow each tool to be optimized for the customer's material, production volume, machine type, and threading requirements.

Since 1989, WESTport has supplied manufacturers throughout North America and around the world with precision thread gages, custom taps, calibration services, hardness testing products, and metrology equipment. Our commitment to quality, technical expertise, and responsive customer service has made WESTport a trusted partner for custom thread-cutting solutions across a wide range of industries.
