How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

These crimpers have individual square crimping slots for each wire gauge.

Confined-Space Wire Ferrule Crimpers

Self-Adjusting Trapezoidal Crimping Slot

Self-Adjusting Square Crimping Slot

Because you insert the wire ferrule from the front, this tool is useful in tight spaces. It automatically adjusts to the proper crimp size for different wire ferrules.

Lever-Operated Crimpers with Dies

Crimpers are furnished with five removable dies that crimp air and water hose. Place your hose, ferrule, and barbed fitting into a die that's inserted in the crimper. Press the lever to crimp the fitting onto the hose. Fasteners not included. Hose OD compatibility is measured without the fittings installed.

Individual dies (sold separately) allow you to crimp sizes of air and water hose from 0.385" to 0.843" OD.

Hose-Crimping Pliers

As you squeeze the handles, the vise-like jaws lock tightly onto the ferrule to secure barbed fittings onto your hose. To select the correct pliers, measure the hose OD and select the next larger size "For Hose OD" below.

Hose Crimping Tool and Fitting Sets for Compressed Gas

Sets contain a crimping tool and a variety of fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.

Barbed adapters let you adapt to a threaded end so you can connect welding hose to pressure regulators or torches. They consist of a barbed shaft with a rounded end that sits inside a threaded nut so you can make a threaded hose connection.

Barbed connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. Slide the barbed end into welding hose and use a hose ferrule and the crimping tool to secure the fitting to hose.

Threaded connectors let you attach threaded welding hose to pressure regulators and torches.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

Crimping Tools for Press-Connect Fittings for Copper Tubing

Create a leak-tight seal without using heat or solder. Slide copper tubing into a press-connect fitting and use these tools to crimp the connection.

Crimping tools seal the fitting in less than five seconds. Lightweight and cordless, you can take these tools to any job. Access your connection from any angle using the pivoting head.

Crimping tools come with two 2.5-amp-hrs.-capacity batteries. Upgrade to a 5-amp-hrs.-capacity battery for over 500 crimps per charge.
