Our DIN 5157 Pipe Tap Sets are engineered for the manual creation and repair of Parallel Pipe Threads (G / BSP). These threads are the global standard for connecting pipes, valves, and hydraulic fittings where a pressure-tight joint is required.
Each set consists of two taps: a Taper Tap (No. 1) to start the thread and a Finish/Bottoming Tap (No. 2) to finalize the profile. By using this 2-step system, our HSS-M2 taps provide a high-precision thread finish that ensures a leak-free seal with minimal manual effort.
High-Speed Steel (M2): Forged from premium HSS-M2 (AISI M2) for exceptional toughness and wear resistance. This is critical for pipe threads, which often involve tapping into tougher steel or thick-walled cast iron.
Bright Finish: The un-coated, precision-ground finish ensures a sharp, clean cut. It is ideal for non-ferrous metals like brass and bronze, as well as general-purpose plumbing steels.
Fully Ground Threads: Our taps are CNC ground from solid hardened blanks, providing a superior thread surface finish compared to traditional rolled taps.
Plumbing & HVAC: Essential for threading galvanized steel pipes, brass connectors, and copper fittings.
Hydraulics & Pneumatics: Used to clean or create threads in manifolds, valves, and cylinders where BSP parallel threads are standard.
Oil & Gas Maintenance: A reliable tool for on-site repair of pressure gauges and sensor ports.
Irrigation Systems: Perfect for heavy-duty commercial piping and water management systems.
Pro-Grade Set Packaging: Each 2-piece set is housed in a durable, shockproof Rose-Box plastic case, preventing the cutting edges from touching during transit.
Long-Term Protection: Every tap is treated with high-viscosity anti-rust oil, ensuring a 3-year safe shelf life even in high-moisture maritime shipping environments.
OEM Customization: Since 1997, we have provided Laser Marking (Your Logo + G Size + HSS + DIN 5157) for our global B2B distributors.
Q: Is G thread the same as BSPP?
A: Yes. The "G" designation stands for parallel pipe threads, which is the same as BSPP (British Standard Pipe Parallel). These are NOT interchangeable with NPT (tapered) threads.
Q: Why use a 2-piece set instead of a single tap?
A: Pipe threads are often wider and remove more material. A 2-piece set distributes the cutting force, making it safer and easier to achieve a high-precision, leak-proof thread by hand.
Q: Can I use these taps on Stainless Steel pipes?
A: While HSS-M2 can handle most steels, for high-volume 304/316 Stainless Steel pipe threading, we recommend our M35 Cobalt (HSSE) series for enhanced heat resistance.
