Prevent Hose Whipping with Hose Whips

hose school | Posted: 8/18/2021

If a coupler connection on an air hose fails, it could result in property damage, injury, or even death. That’s why restraints, such as whip checks, are often used to reduce the movement of an air hose in the event of hose, coupler, or fitting failure.

What is a “Whip Check”?

A whip check is a steel cable with loops on each end. These loops are positioned on both sides of a hose connection to keep the hose from moving if the connection fails. It’s important to be sure to keep the loops a few inches behind the fittings, not on them, as the typical failure point in a hose system is behind the fitting itself. This means that if your whip check is attached to the fitting and the hose fails, the hose will start “whipping”.

Whip checks are recommended for air systems with a psi of about 200. At this level, they are designed with a 5 to 1 safety margin, which means they have been tested at 1,000 psi. However, this doesn’t mean you should test these upper limits! At 300 psi, this safety margin drops to 3 to 1. Here at, we have whip checks in stock that will accommodate anything from a ½ inch hose to a 5-inch hose.

Part Number: XXXWHIPS. This whip check fits 1/2" to 1-1/4" hose

How to Install a Whip Check:

Proper installation of your whip check is one of the most important steps you can take to ensure you are protected. To install just follow these easy steps:

  1. Pull back on the spring-loaded loop and slide the opening around the end of your hose.
  2. Do the same with the other end of the whip check and connect your hose or hoses appropriately.
  3. At this point, you will have a u-shaped bend in the whip check.
  4. Before completing the installation, you must minimize the amount of slack in the cable as much as possible, otherwise, your whip check won’t be doing its job.
  5. Move each side of the whip check an equal distance from the fitting until the whole thing lies flat against the hose.
  6. If you notice an excessive difference, such as six inches of whip check on one side and fourteen inches on the other, you’ll need to adjust the fit.
  7. Once you have installed the whip check, you’re ready to go!

Our line of safety cables is great for applications in environments with a lot of moisture since they’re highly resistant to rust and corrosion. So, if you work outdoors, or in a shop that uses air tools, you can rest easy knowing that the whip check will keep you safe! Most commonly, a whip check is used on large air compressors with hoses like the Continental Contitech Frontier™ Air-Water Hose.
