Pipe and Conduit Thread Taps

Create threads sized for pipe and conduit.

Long-Reach Pipe and Conduit Thread Taps

With an extra-long shank, these taps have extended reach for tapping deep and hard-to-reach areas in pipe and conduit.

Left-Hand Pipe and Conduit Thread Taps

Tap left-hand threads for pipe and conduit.

Economy Carbon Steel Pipe
and Conduit Thread Taps

Use these carbon steel taps for thread repair and occasional tapping of pipe and conduit. They can tap threads into most metal and plastic, but they have a shorter tool life than standard taps.

Pipe and Conduit Thread Taps for Shallow Holes

Also known as short-projection taps, these have fewer tapered threads at the tip than standard pipe taps, so you don't have to drive them as deep to produce full threads.

Chip-Clearing Pipe and Conduit Thread Taps

Also known as interrupted-thread taps, these have extra space between the cutting threads, so large chips fall without packing and high amounts of lubricant can flow between the tap and the workpiece.

Combination Drill Bit/Pipe and Conduit Thread Taps

Drill and thread holes for pipe and conduit without switching tools.

Pipe and Conduit Thread Taps
with Two Threading Ends

With a taper chamfer on one threading end and a bottoming chamfer on the other, these pipe and conduit taps can start threads easily, and they are able to thread close to the bottom of closed-end holes.

Pipe and Conduit Thread Taps
for Stainless Steel and Plastic

The spiral flutes on these pipe and conduit taps keep chips clear by drawing them back out of the hole, so there's no need to reverse the tap while cutting threads.

Pipe and Conduit Thread Taps for Hardened Steel

Use these taps on hardened steel pipe and conduit.

Pipe and Conduit Thread Taps
for Aluminum, Copper, and Brass

The cutting teeth are shaped to cut smooth threads in soft pipe and conduit material.

European Conduit Thread Taps

Cut threads in PG thread sizes commonly used for European conduit.

Control of Liquids, Gases, and Solids

Tap Valves

Also known as saddle valves and humidifier valve clamps, these self-piercing valves allow you to tap existing copper tubing lines to redirect a small amount of liquid for on/off control of a secondary line.

Pressurized Pipe Tapping Kits

Also known as hot tapping kits, these kits include the tools you need to add a new line without having to shut down your piping system.
