14 best pipe taps
Pipe taps, also known as pipe threading taps or simply taps, are cutting tools used in industrial and plumbing applications to create internal threads in pipes and pipe fittings. These internal threads allow pipes and fittings to be joined together securely, typically using threaded connections.
Here are some key points about pipe taps:
Purpose: Pipe taps are used to cut threads inside the bore of pipes or pipe fittings. These threads are essential for creating leak-proof connections in plumbing, gas lines, and other fluid-carrying systems.
Types: There are several types of pipe taps, including taper taps, plug taps, and bottoming taps. Taper taps have a more gradual cutting action and are often used for starting threads. Plug taps are used for intermediate threading, and bottoming taps are used to finish the threading process, ensuring threads extend to the bottom of the hole.
Material: Pipe taps are typically made from high-speed steel (HSS) or cobalt steel, which are known for their durability and resistance to wear. The choice of material depends on the specific requirements of the application.
Thread Standards: Pipe taps follow specific thread standards, such as NPT (National Pipe Thread), BSP (British Standard Pipe), or metric pipe threads. These standards dictate the thread profile and pitch, ensuring compatibility between pipes and fittings.
Size and Pitch: Pipe taps come in various sizes and thread pitches to accommodate different pipe diameters and requirements. Common sizes include 1/8", 1/4", 3/8", 1/2", 3/4", 1", and larger, with corresponding thread pitches.
Use with Tapping Tools: Pipe taps are used in conjunction with tapping tools, such as tap wrenches or tapping machines. These tools hold the tap securely and facilitate the cutting process.
Lubrication: When using pipe taps, it's essential to apply cutting oil or lubricant to the workpiece to reduce friction, heat, and wear on the tap. Proper lubrication helps prolong the life of the tap and ensures smoother threading.
Safety: Users should exercise caution when working with pipe taps, as they involve sharp cutting edges. Wearing appropriate safety gear, such as safety glasses and gloves, is advisable. Additionally, maintaining proper technique and alignment while threading is crucial for safety and the quality of the threads.
Pipe taps are vital tools in industries such as plumbing, construction, and manufacturing, where threaded connections are commonly used to ensure the integrity and functionality of pipelines and systems. Proper selection and use of pipe taps are essential to achieving reliable and leak-free threaded connections.

User questions & answers
| Question: | What is the dimension across the flats on the shank |
| Answer: | No |
| Question: | Do you have pipe thread tap cs3/8"-19 bspf |
| Answer: | Use an 8 point socket, 3/8 if I remember correctly. That and a ratchet and or a 3/8 drive slide bar handle work well. |
| Question: | I have been unable to find a tap wrench that will fit this tap. Can anyone suggest one that will fit |
| Answer: | A tap die extractor means a tap which is used to "chase' the threads in a pre-existing threaded hole. Conversely, a die extractor, is essentially a die which is used to chase, or to re-thread. I have tried using this tool to make brand new threads in a hole. Believe me ... it is doable ... but extremely difficult to do. |
| Question: | What does "for tap die extraction" mean in the title? Maybe I'm having a mental block but that makes no sense to me |
| Answer: | Yes,exactly what I used it for.needed to restore an existing connection. And it did. Mine was a 2” connection though,2”ridged is 2 1/2”od hope this will help answer your question.. |
