Emkay High Speed Steel HSS BS 949/ANSI Pipe Taps NPSF

Features of Emkay High Speed Steel (HSS) BS 949 / ANSI Pipe Taps – NPSF

1. High-Quality HSS Construction – Made from premium High-Speed Steel for superior durability, heat resistance, and long-lasting performance.

2. NPSF Thread Profile – Designed to cut National Pipe Straight Fuel (NPSF) threads, commonly used for dry-seal female pipe connections.

3. Straight (Parallel) Threads – Produces precision parallel threads that work with NPTF male fittings for leak-free, dry-seal applications.

4. Complies with BS 949 / ANSI Standards – Ensures accurate threading, consistency, and compatibility with standardized fittings.

5. Hand Tap Format – Suitable for manual tapping using tap wrenches, perfect for workshop, fieldwork, and maintenance tasks.

6. Dry-Seal Capability – Creates tight mechanical seals without the use of thread sealants or Teflon tape.

7. Precision Ground Flutes – Delivers clean cuts, smooth thread finishes, and efficient chip evacuation.

8. Versatile Material Compatibility – Effective on a variety of materials including steel, stainless steel, brass, aluminum, and cast iron.

9. Corrosion and Wear Resistant – Built for tough environments and frequent industrial use.

10. Available in Multiple Sizes – Offered in a range of NPSF sizes to suit different application needs across industries.

Applications For uses : 

1. Hydraulic Systems – Used to tap NPSF female threads that pair with NPTF male threads, creating leak-free, dry-seal joints in high-pressure hydraulic lines.

2. Pneumatic Equipment – Ideal for air systems where straight-threaded female ports are needed for dry sealing.

3. Fuel and Oil Transfer Lines – Commonly used in automotive, aerospace, and industrial applications where NPSF ports connect to NPTF fittings without thread sealant.

4. Manufacturing of Valves and Fittings – Taps precise NPSF threads in components that require dry-seal capabilities.

5. Instrumentation and Control Panels – Creates reliable threaded ports for gauges, sensors, and pressure fittings.

6. Industrial Equipment Assembly – Applied in machinery that requires NPSF-threaded ports for secure, no-leak connections.

7. Maintenance and Repair Work – Handy for rethreading or restoring NPSF female threads in worn or damaged parts.

8. Marine and Offshore Systems – Used in fuel, oil, and fluid systems requiring high-integrity, dry-seal thread joints.

9. Chemical and Process Industries – Ideal for leak-free threaded joints in fluid transport systems that can’t use sealing compounds.

10. General Engineering and Fabrication – Suitable for creating precision dry-seal threads in a wide variety of custom and OEM parts.
