Emkay High Speed Steel HSS BS 949/ANSI Pipe Taps NPS / NPSM

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

1. Made from Premium High-Speed Steel (HSS) – Delivers excellent durability, wear resistance, and long service life.

2. Straight (Parallel) Thread Design – NPS (National Pipe Straight) and NPSM (National Pipe Straight Mechanical) taps cut non-tapered threads, ideal for mechanical joints.

3. Compliant with BS 949 / ANSI Standards – Ensures thread accuracy, consistency, and compatibility with standardized pipe fittings.

4. Ideal for Mechanical Sealing – Designed for applications where sealing is done with a gasket, O-ring, or washer—not by the threads.

5. Hand Tap Style – Perfect for manual operations using tap wrenches, suitable for both shop floor and on-site work.

6. Precision Ground Flutes – Provides smooth thread cutting and excellent chip clearance for cleaner finishes.

7. Versatile Use – Effective on a wide range of materials like steel, brass, aluminum, cast iron, and plastics.

8. Corrosion and Heat Resistance – Built to withstand tough environments and frequent usage.

9. Excellent Thread Finish – Produces clean, reliable threads suitable for mechanical assembly and industrial use.

10. Multiple Sizes Available – Offered in a variety of NPS and NPSM sizes to suit different pipe and fitting requirements.

Applications For uses : 

1. Mechanical Piping Systems – Used for cutting straight (parallel) threads in pipes and fittings where sealing is achieved via gaskets or O-rings.

2. Fire Protection Systems – Ideal for threaded connections in sprinkler systems where mechanical seals are used.

3. Compressed Air and Gas Lines – Suitable for threading joints in non-tapered pipelines requiring mechanical sealing.

4. HVAC Installations – Commonly used in ducting and fluid handling where straight thread fittings are specified.

5. Industrial Equipment Manufacturing – Perfect for machining threaded ports and connectors that rely on mechanical seals.

6. Water Filtration and Treatment Systems – Used for straight thread connections in filtration housings and pipe joints.

7. Chemical and Pharmaceutical Industries – Applied where precise, non-tapered threaded fittings are needed in containment and fluid systems.

8. Marine and Shipbuilding – Suitable for threaded components in systems that use sealing washers or gaskets.

9. Maintenance and Repair Operations (MRO) – Ideal for rethreading or restoring existing NPS/NPSM threads in equipment.

10. General Fabrication and Workshop Use – Used in custom assemblies, enclosures, or pipe joints needing straight-thread compatibility.
