Frequently Asked Questions
What is the difference between straight and taper pipe thread taps?
Straight pipe thread taps produce threads of uniform diameter, used for pressure-tight joints without sealant (NPS). Taper pipe thread taps have a tapered profile (1/16 inch per foot) that creates a seal when combined with PTFE tape or thread sealant (NPT). Taper taps are more common for most pipe fitting applications.
What materials can these taps cut?
These HSS taps are suitable for cutting threads in carbon steel, stainless steel, brass, copper, and other common marine metals. Always use appropriate cutting fluid to extend tool life and improve thread quality.
What thread standards are available?
We offer taps for NPT (National Pipe Taper) and BSPT (British Standard Pipe Taper), as well as straight versions like NPS or BSP. Specify your required standard when ordering to ensure the correct tap for your workpiece.
Can I use these taps by hand or with a machine?
Both hand tapping (using a T-wrench) and machine tapping (with a tapping chuck) are possible. For machine use, ensure proper spindle speed and alignment to prevent tap breakage.
