Hose Clamps

When attaching a hose to a fitting, typically a barbed insert or a nipple, PVC cement will not hold them together. Because hoses are flexible, they cannot be glued to fittings. Because of this, it is necessary to use some type of exterior clamp to hold hoses onto fittings. Our selection of stainless steel (SS) hose clamps will do just that. In sizes from ½” to 10”, our clamps will accommodate a wide range of hose and fitting sizes.

About Hose Clamps

Hose clamps come in a few different forms, but the ones we stock are screw/band (or “worm gear”) clamps. Worm gear hose clamps are named after the type of gear movement they use to tighten the band. The tightening apparatus is made up of a captive screw and a metal band. As the screw is turned, its threads pull one end of the band towards it, making the space inside the band smaller.

This design, as well as the 300-grade stainless steel they are composed of, lets our worm gear hose clamps withstand a great deal of pressure without slipping or loosening. These SS hose clamps will only loosen when the screw is turned and are made of a material that will not bend or break easily. When used in typical automotive and household applications, these hose clamps will hold strong!

Hose Clamp Sizing

Each of our SS hose clamps is rated for a range of sizes each, but make sure you check the product descriptions for the “Fits Nominal PVC Size” section. Because PVC pipe is typically sized based on the interior diameter of the pipe, the size in the name is not actually the size of the pipe itself. For more information on PVC pipe sizing, read this helpful article.

This means that, for example, a 3”-4” hose clamp can be used for 3” PVC fittings but not for 4” fittings. If you put that hose clamp around a hose and 4” fitting, there would be a higher chance of the worm gear slipping. To get the most out of a hose clamp, make sure to use them on hoses and fittings that are on the lower end of their size range. Some of our SS hose clamps can even be used for nominal PVC sizes that are slightly lower than the low end of the clamp’s range. To be sure you get the right size hose clamp, read all the details at the bottom of the product page to find out which nominal PVC size it fits.

Frequently Asked Questions

Why is stainless steel preferred for hose clamps?

Stainless steel is the preferred material for hose clamps for a few reasons. First, it does not rust or corrode, even when exposed to water over time. This means our SS hose clamps can be used for water transportation and even marine use. Another great reason for using stainless steel is for its strength. Stainless steel is a durable alloy that is built to last.

When are hose clamps commonly used?

Because of these are worm gear hose clamps, they are limited to more moderate pressures. This means they ar
