How to Buy a Hose Clamp for Your Car
The vacuum pump of your car might require a hose clamp in case your engine vacuum pump hose and vacuum adapter require a tighter, leakage-free fit. The hose clamp or clip is a device you can use to attach and altogether seal a hose unto a fitting such as a vacuum adapter, nipple, or barb. They typically see use in home and automotive applications. It does have limits to when it can and cannot work, though.
The Different Types of Automotive Hose Clamp
There are multiple types of hose clamp for you to choose from, which includes the following:
- Screw or Band Clamps: Screw, band, or worm gear clamps are hose clamps consisting of stainless steel or galvanized bands with a screw thread pattern that's been pressed or cut. The clamp wraps around the tube to be connected while the loose end is fed in the space between the captive screw and the band. As the screw turns, it serves as a worm drive pulling the threads to the band and tightening it in the process.
- Spring Clamps: These hose clamps are made from a spring steel strip that's cut so one side has a pair of narrow protrusions on either side and the other side has a narrow protrusion centered on the end. These protrusions are then bent outwards, rolled to form a ring, and have the tabs mesh with each other. This clamp requires pliers for you to press the exposed tabs together in order to tighten its grip on your hose.
- Wire Clamps: As for wire clamps, these hose clamps is made up of heavy (steel) wire bent into a U-shape then formed into a ring with one end overlapping the other end. From there, the ends are bent outwards and cut out. As the screw is tightened on one end towards a captive nut on the other end, the overlapping ends are pushed apart, which tightens the loop around the hose.
- Ear Clamps: This hose clamp variant is made of a stainless steel band with one or more ears (closing elements) formed. This clamp is placed over the hose's end to be connected with its ears. Once the ear is closed using a special pincer tool, the clamp permanently deforms as it pulls the band and tightens its grip around the hose's nozzle altogether. The ears of every ear clamp should be almost completely closed once installed.
- Other Clamp Types: Other hose clamp types include compression fittings that compress soft metal ferrule or nylon onto the hose as the fitting is tightened, push-fit fittings that involve inserting the hose inside the compression sleeve wherein the force against the hose makes the sleeve tighten, swage fittings that has a stiff collar compressed unto the hose, clamp fittings that use two blocks to tighten on the sides of the hose, and so forth.
There are clamps aplenty to choose from as far as automotive hose clamps are concerned. These clamps are quite dependable when it comes to ensuring leakage-free sealing. It can assist adaptors and sealants in sealing in the hose to make sure that only specific liquids or gases could come through it without leakages coming out from the opening. It's particularly useful in sealing up ill-fitting connections between hoses and connectors, which saves motorists on the rush time and energy to finding perfect-fitting hose components.
