25mm Diameter Black Plated Single Ear Stepless Hose Clamps

Vacuum Spring Fuel Oil Water Black Hose Clip Pipe Tube for Band Clamp

APPLICATION - Hose clamps used to seal various types of hoses, pincers can increase clamp force, designed for repairing pipes & plumbing systems. Widely used in securing hoses, pipe, cable, tube, fuel lines etc. Perfect for automotive, industrial, boat/marine, shield, household etc. both indoor and outdoor.

Cochlear design ensures continuous clamping during temperature changes or machine vibrations, edge polished smooth, avoid damage to the hose.

These clamps are universal and will work with any brand of crimp style PEX fittings or PEX tubing.

Interlocking ring that forms a complete 360-Degree watertight seal

Perfect for connecting PEX to crimp type fittings in hard to reach spaces

Some such clamps feature dimples intended to provide a spring effect when the diameter of the hose or tube contracts or expands due to thermal or mechanical effects.

A stepless type of ear clamp is which eliminates steps or gaps on the inner circumference of the clamp. This is said to provide uniform compression and a 360° seal. Such stepless clamps are claimed to be well suited to applications involving thin-walled hoses, supposedly with higher retained loads. This suggests they should be considered for difficult to seal applications such as molded plastics or other less malleable materials, commonly used in the automotive industry.

Many other methods can be used to attach hoses or tubing, such as compression fittings (where a nylon or soft metal ferrule is compressed onto the hose by the tightening of the fitting), push-fit fittings (where the hose is inserted inside of a compression sleeve, designed such that force against the hose causes the sleeve to tighten), swage fittings (where a stiff collar is compressed onto the hose), clamp fittings (where two blocks are tightened onto the sides of the hose, often found on garden hoses), crimp banding (similar to worm gear banding but a crimp is used instead of a screw/thread), and a multitude of others. However, these devices are not typically referred to as hose clamps.

Hose clamps are frequently used for things other than their intended use, and are often used as a more permanent version of duct tape wherever a tightening band around something would be useful. The screw band type in particular is very strong, and is used for non-plumbing purposes far more than the other types. These clamps can be found doing everything from mounting signs to holding together emergency (or otherwise) home repairs.

Another handy attribute: worm-drive hose clamps can be daisy-chained or "siamesed" to make a long clamp, if you have several, shorter than the job requires.

Some things seen assembled with hose clamps include the tail boom on a GMP Cricket model helicopter, a homemade gas scooter, makeshift pipe hangers, mounts for rooftop TV and shortwave antennas, and virtually every imaginable automobile body component.

Hose clamps are commonly used in the agriculture industry as well. They are used on Anhydrous Ammonia hoses and are made from a combination of steel and iron. Anhydrous ammonia hose clamps are often cadmium plated to prevent rust and corrosion.

To ensure a good seal, the barb, hose nipple, or beaded tube must be smooth and free of nicks, scratches, or contamination. Stuck hoses should never be removed by slitting them, as this can leave a scratch on the fitting which will cause a leak.

The other goal of a hose clamp is to provide mechanical attachment keeping the hose attached to a barb, hose nipple, or tube. To do this the clamp is typically placed on the hose behind the first ramp of the barb or behind the raised area near the end of and completely around the circumference of the hose nipple or tube called a bead. If the hose were to slide the clamp would have to expand to fit over the barb or raised bead. This keeps the hose attached to the barb, hose nipple, or beaded tube.
