How to Choose the Best Pipe Taps
Understanding Pipe Tap Types
Pipe taps are designed for specific thread standards. The most common are NPT (National Pipe Taper) and NPS (National Pipe Straight). NPT threads are angled, creating a seal when tightened, while NPS threads are straight and require sealant. Ensure the tap matches the pipe threading you are working with.
Material and Durability
High-speed steel (HSS) is a common and durable material for pipe taps, offering good resistance to wear and heat. For tougher materials or frequent use, consider taps with a titanium nitride (TiN) coating, which further enhances hardness and reduces friction. Check the tap's construction for overall quality and longevity.
Tap Size and Thread Count
Pipe taps are sized by the nominal pipe size they are intended for (e.g., 1/2 inch, 3/4 inch). The thread count (TPI - threads per inch) is also critical and is determined by the pipe size and standard. Always verify the tap's specifications match the pipe's threading requirements precisely.
Frequently Asked Questions
What is the difference between NPT and NPS taps?
NPT (National Pipe Taper) taps create tapered threads that seal tightly when the fitting is screwed in. NPS (National Pipe Straight) taps create straight threads, which require additional sealant like tape or paste to prevent leaks.
How do I choose the correct size pipe tap?
Pipe taps are sized according to the nominal pipe size they are intended to thread. For example, a 1/2-inch pipe tap is used for 1/2-inch nominal pipe. Always confirm the tap's designation matches the pipe you are working with.
What is the best material for a pipe tap?
High-speed steel (HSS) is a popular choice due to its durability and heat resistance, making it suitable for most common plumbing tasks. For demanding applications or threading harder materials, consider HSS taps with a titanium nitride (TiN) coating for enhanced hardness and longevity.
Can I use a pipe tap on a straight pipe?
Generally, you should use an NPT tap for tapered threads and an NPS tap for straight threads. Using the wrong type can result in a poor seal or damage to the pipe fitting.
