What are hose clamps?

A hose clamp is an accessory that attaches onto a hose fitting. They are meant to help seal and stabilize any hose configuration. Essentially, clamps help stop moving fluid from escaping from around a configuration by creating equal pressure all around and preventing gaps for internal fluids that could potentially cause a dangerous leak.

What equipment do we use for hose crimping?

South Texas Specialties currently has a TC450 crimper, which has an electronic controller and can produce 340 tons of crimping force with the capability to crimp up to 2-1/2" spiral hoses and 3" industrial hoses. We also have a PC125 crimper, which features an open design, removable pusher and easy-to-use, spring-loaded die set, and is designed for higher production volume and repetitive use.
