This can lead to leaks, which can cause water damage and other problems.

Types of pex crimp tools

Pex tubing tools fall into three categories they include:

  • Connectors (crimp and clamp).
  • Pipe cutters
  • Tools for securing tubing on a wooden surface (clip guns and staplers.)


Crimper: This is the most popular tool for making pipe connections. It uses a copper ring to make a leak free joint.

it is compatible with brass fittings and other sizes ranging from 3/8″ to 1″, and all other pex tools except PEX-AL-PEX.

Clamp tool: This is like a crimping tool, the only difference is that it uses a stainless clinch instead of copper ring.

It is a universal tool that can work with all clamps and fittings ranging from size 3/8 to 1″


This helps an installer to make a clean and straight cut for a proper connection of the tubing to a fitting.

Pex cutters come in various sizes, both in light duty types for pipe size of 3/4″, and professional ratcheting types for pipes of 1-1/4 inches.

Foamboard Stapler Tools

This is used when pex tubing is installed in a concrete slab on top of EPS or XPSpolystyrene insulation.

It is often loaded with staples and when you push the tool handle; the installer drives the U-shaped staple, securing the pipe firmly.

Clip gun:

This is a pex to wood attachment tool similar to a stapler. It is available in both manual and pneumatic. Clip guns are available in different tube sizes ranging from 3/8″ to 3/4 inches.

How to use the pex tool

Using this connector is easy, just follow these steps.

  • Cut the pipe to your required size
  • Slide the crimper ring onto the pipe you cut
  • Fit the pipe to the tube and push it ON
  • Move the ring to the edge
  • Open the crimper by pulling both handles
  • Place it firmly on the ring and push both handles to crimp.

Things to consider before buying a new pex tool

Before buying a new connector, there are certain things to consider. They include:

Crimp vs clamp

These days, it is rare to get one device that can crimp and cramp. It is therefore advisable that you make your choice before buying,

The crimp is a copper ring that slides over a joint to grip the tube. They are burlier than clamps, but are more prone to corrosion.

The clamps are stainless still bands with small pegs and holes. Clamping tools squeeze a knob till the peg lands in the correct hole, securing it on a barbed fitting inside the joint.

Stainless clamps are easier to install, hard rust but are thinner, and can easily bend or separate.

Length of the tool handle

The handle of a Pex tool can be long or short and your place of work determines the type to use.

If the pipe is in an area that requires a long-handled tool, go for it otherwise, buy a short-handled pex tool.

Easy to use

Before buying your desired tool, make sure it is easy to use and also has all the qualities you need
