Product Overview

The BSPP solid carbide straight flute pipe tap—also referred to as the PF/G parallel pipe thread tap—is a high-precision tool designed for creating British Standard Pipe Parallel (G thread) internal threads. Ideal for applications that require mechanical fastening or thread sealing with a gasket or O-ring, this tap delivers outstanding performance in abrasive or hard-to-machine materials.

Manufactured from ultra-fine grain tungsten carbide, our BSPP tap offers exceptional rigidity, edge retention, and wear resistance. The straight flute geometry is optimized for through-hole tapping and short chip materials such as cast iron, brass, aluminum alloys, and mild steel. It is a trusted solution for high-volume CNC production, as well as precision applications in fluid, air, and mechanical systems.

Key Features

• Thread Standard: BSPP / PF / G (British Standard Pipe Parallel, 55° Whitworth thread)

• Material: Ultra-fine grain solid carbide (tungsten steel) for long tool life

• Straight Flute Design: Ideal for through-hole tapping and consistent chip control

• Precision Ground Threads: Delivers uniform pitch and tight dimensional tolerances

• Excellent Surface Finish: Clean, burr-free threads ideal for leak-free sealing with washers or gaskets

Applications

• Threading parallel pipe threads in hydraulic components, valves, manifolds, fittings, and housings

• Ideal for aluminum die castings, brass fittings, ductile iron, and non-ferrous alloys

• Commonly used in pneumatics, HVAC, water filtration, and low-pressure fluid systems

• Suitable for CNC machining, automatic tapping machines, and high-precision manual setups

Advantages

• Accurate thread geometry ensures tight fit and consistent torque

• High-speed performance in CNC tapping with low risk of deflection or chipping

• Exceptional tool life in mass production and abrasive materials

• Optimized for through holes in short-chipping materials

• Compatible with rigid tapping, synchronous spindles, and manual setups

Usage Recommendations

• Always match the correct pre-drill diameter for BSPP threads

• Use cutting oil or coolant to extend tool life and prevent chip welding

• For best results, use on machining centers with tapping cycles

• Avoid in blind holes or long-chip materials (consider spiral flute variants for those cases)
