Hose clamps are used to fasten a hose over a connector, e.g. a spigot or barb, and act as a seal to prevent leakage of liquid at the connection. They also stabilize the hose connection. They are mainly used in the plumbing and automotive industries, but also in other applications and to prevent leaks when transporting liquids, chemicals and gases.
Hose clamps are durable & stable. The hose clamps can be hand tightened without the screw slipping or distorting the screw cage and use a providing reliably strong and stable clamping force. It should have a long-lasting hold that is most ideal for a few demanding applications. Common uses for hose clamps include securing hoses in automotive systems and for clamping lines in household plumbing systems. Hose clamps also work well in other situations where a user desires a strong band clamp, like applications where a zip tie or duct tape might be used.
There are three main types of hose clamps:
1. Plastic Hose Clamps
Ratchet teeth interlock to ensure a strong, secure connection. These can be quickly installed by hand and tightened with pliers to tighten the handle. Sometimes referred to as a snap grip, snapper, or herbie, these hose clamps are made of plastic. Nylon is a good choice as it is strong and offers flexibility for easier closure. Economical, lightweight and reusable.
2. Worm drive hose clamps
These hi-torque worm clamps are the style meant when referring to jubilee clips. They feature a helical-threaded screw, or worm gear, which is housed in the clamp. When the screw is turned, it acts like a worm-drive pulling the threads of the band. The band then tightens around the hose or tube.
The high clamping force makes this a heavy-duty jubilee clip. Available as stainless-steel or steel hose clamps, these are ideal when space is restricted or hard to reach. NOT recommended for soft or silicone hose.
3. T-Bolt Hose Clamps
Designed to provide a tight, secure seal in larger diameter applications where high levels of vibration are encountered. The clamp screw is inserted through the hole in the hose clamp body. Then the nut is tightened from below with a wrench or pliers. As a stainless steel hose clamp, T-Bolts are ideal as high pressure hose clamps and for use with silicone hoses.
