Plumbing System Tumbled SUS304 Single Ear Stepless Hose Clamps

Stainless Steel #304 Stepless Single Ear Hose Clamp for Securing Pipe Hoses and Automotive Use
 
MATERIAL - 304 Stainless Steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties.
FEATURES - Form a complete 360-Degree watertight seal. There is no protrusion and gap in the inner, narrowband design providing a more concentrated sealing pressure.
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
 
Ear Clamps consist of a band (usually stainless steel) into which one or more “ears” or closing elements have been formed. The clamp is placed over the end of the hose or tube to be connected and when each ear is closed at the base of the ear with a special pincer tool, it permanently deforms, pulling the band, and causing the band to tighten around the hose. The size of clamp should be chosen such that the ear(s) are almost completely closed on installation.
 
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.
 
Other features of this style of clamp include: narrow band widths, intended to provide a concentrated compression of the hose or tube; and tamper resistance, due to the permanent deformation of the clamp’s “ear”. If closure of the clamp “ear(s)” is performed to manufacturer's recommendations, which generally provide for constant jaw force, the sealing effect is not unduly sensitive to component tolerance variations.
 
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 typically limited to moderate pressures, such as those found in automotive and home applications. At high pressures, especially with large hose sizes, the clamp would have to be unwieldy to be able to withstand the forces expanding it without allowing the hose to slide off the barb or a leak to form. For these high pressure applications, compression fittings, thick crimp fittings, or other designs are normally used.
 
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.
 
One of the fundamental goals of most hose clamps is to ensure a tight seal between the hose and the barb, preventing the working fluid from escaping. To this goal, they are designed to provide even pressure on all sides, with no gaps. An example of this would be wire clamps. An obvious design would seem to be simply having a wire around the hose, one end attached to a nut, and the other end to the screw, and when tightened, pulling the ends of the wire towards each other. However, this will leave a gap where no pressure is applied (underneath the screw), and cause a leak. To combat this, the more complicated and weaker design of having the ends overlap and then be pushed apart from each other is used, as this ensures pressure around the entire circumference of the hose.
 
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.
