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.

About Measuring Hose and Tube Clamps
What's the best way to determine the clamp size you'll need? Simply measure the outside diameter of your hose with the fitting installed. Some clamps accommodate a range of sizes, so be sure the size you need falls in the middle of that range.

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.
Lever-Operated Crimpers
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. Use with aluminum or brass ferrules. Fasteners not included.
Individual dies (sold separately) allow you to crimp large sizes of air and water hose from 3/4" to 1 3/8" OD (measured without the fittings installed).

Installation Tools for Push-On Barbed Hose Fittings
This tool allows you to connect large quantities of barbed fittings to push-on hose. Use the built-in cutter to squarely cut push-on hose without fraying. Next, lubricate either the push-on hose, fitting or both. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting.

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 Barbed Tube Fittings for Drinking Water
Use these tools with a crimping ring (sold separately) to connect barbed tube fittings for drinking water to tubing. Compatible with Viega PEX fittings.
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.
Jaws fit directly into a crimping tool to clamp copper tube sizes 1/2 to 2.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
Use rings for copper tube sizes 2 1/2 to 4. Clip the ring around the fitting and use the included ring actuator jaw and crimping tool (sold separately) to press the open ends together.

Hose and Tube Clamp Pliers
Install hose and tube clamps with these specially designed pliers.
Pinch clamp pliers crimp pinch clamps closed on hose and tube. Those with straight jaws must be used perpendicular to the hose. Pliers with straight and side jaws are good for tight spaces because you can use them parallel or perpendicular to your hose. Pliers with a center handle reduce the fully open grip span. They also have a higher closing force than other pliers, so they require less strength to crimp pinch clamps closed.
Cushion grip pliers have plastic grips for comfort. Ultra grip pliers have a grip made of hard and soft materials for comfort and slip resistance. They are shaped to fit comfortably in your hand and reduce strain from repetitive tasks.
