Different Types for Different Situations
Tubing or reinforced hose needs to be securely attached to another piece of equipment by use of a fitting. Manufacturers of hose and tubing recommend the use of some sort of clamp to help hold the tubing and the fitting together. Without a clamp the potential for the two components to separate, resulting in a leak, exists.
There are several types of hose clamps and each has its place depending on the application. This article will focus on three styles – ear type, worm gear and double bond. They're used in industries such as food and beverage, chemical, laboratory, medical, OEM, MRO, aerospace and aviation, pool and spa, automotive, appliance, marine and others.
Ear type clamps are tightened around tubing when part of the clamp is pinched using a special tool. They're known as breathable clamps, because they adapt to expansion and contraction – a benefit when varying temperatures are involved. Ear type clamps are lightweight and typically made from stainless, galvanized or zinc-plated carbon steel. They offer a compact design, making them well suited for limited-space applications. Pincers must be used to tighten ear type clamps.
Worm gear clamps, which are also known as screw clamps, are installed with a standard screwdriver or ratcheting socket. Tightening the screw pulls a band through a housing, thereby tightening the band around the hose or tubing. Like ear type clamps, they are constructed of steel. Styles designed to work with soft tubing, such as silicone, and with harder tubing and hose materials are available.
When a non-metallic clamp is desired, double bond clamps, commonly made of nylon, may be used. Double bond (also called double grip) clamps offer two rows of teeth to ensure a strong hold and can be easily adjusted for a tighter fit around tubing. These clamps are non-conductive and will not rust or corrode. The only tool required is a pair of pliers or channel locks to tighten the clamp.
