Pipe is measured by inner diameter, and tube is measured by outer diameter. While they may look the same, the hole size in the clamp may be different. Please select which item you need to clamp.

A Coupling Half is a metal coupling. The insert, also called a spider, is made of various rubber-like materials. Usually one coupling half is on the pump side shaft, one coupling half is on the motor/engine side shaft, and the Insert is sandwiched in between the two.

This is the material that the item is primarily made of. Additional materials may be used in item construction, please see data sheets for details.

Is the connection a Male, Female or Flange?

'F' Indicates Female, 'M' Indicates Male

This is the material that the item is primarily made of. Additional materials may be used in item construction, please see data sheets for details.

Clamps are available in many styles based on how you need to mount the clamp. The 'Heavy' version of the clamp offers thicker clamp construction. We recommend heavy clamps for systems over 3000psi or in more rugged applications.

This is the dimension of the outside of your tube or pipe. This is going to be the diameter of the hole in the clamp.

Tube is measured based on the outside diameter of the tube. Please select your size of tube to be matched with the appropriate clamp.

Pipe is measured based on the inside diameter of the tube. Please select your size of pipe to be matched with the appropriate clamp.

Hardware includes all metal parts (cover plate, weld plate, bolts, rails, etc.). 316SS is recommended in marine or caustic applications where corrosion may be an issue.

This is the texture of the hole in the plastic insert. When clamping pipe or tube, we recommend a profiled (ribbed) texture. When clamping hose, we recommend a smooth texture.

Clamps of a certain bore size may be available in multiple group sizes. The larger the group size, the more heavy-duty the clamp. You may choose to go up in group size if your application requires a more rugged clamp.

This is the maximum allowable working pressure (MAWP). Never allow your pressures to go above this rating.

What type of fluid will you be running in your system?

A Keyed Coupling has a smooth shaft with a metal notch called a keyway. A splined coupling has a shaft with notches or teeth.

Are you mounting to an engine, a European motor (IEC Metric), or a USA motor (NEMA)?

Adapters can come with 4 Bolt Holes, 2 Bolt Holes, or in some cases 6 bolt holes to accommodate both 2-Bolt and 4-Bolt configurations.

The XM Dimension is the length of the pump/motor adapter from the outer edge of the pump side to the outer edge of the motor side, AKA the overall length. See literature for details.

The CL Dimension is the length of the pump/motor adapter from inside the lip on the pump side to the outer edge of the motor side. See literature for details.

The Pump Pilot Dim XAK is the size of the hole in the adapter on the pump side. See Literature for details.

This is the Center-to-Center Dimension of the pump side mounting holes for a 2-bolt mount pump. See Literature for Details.

This is the Center-to-Center Dimension of the pump side mounting holes for a 4-bolt mount pump. See Literature for Details.

IMPORTANT NOTE: Your coupling series must match for all items in your coupling set. For example, if your motor requires a 500 series coupling half, you must match it to a 500 series pump side coupling half, and a 500 series insert.
