A 4″ hose clamp (hose clip, hose lock or Jubilee clip (UK)) is a device used to attach and seal a hose on to a fitting like a barb or nipple. Many kinds can be purchased, such as :

Attach/music group (worm equipment) clamps

Screw clamps contain a music group, frequently galvanized or stainless, into that your attach thread pattern has been cut or pressed. One finish of the music group has a captive attach. The clamp is put around the garden hose or pipe to get connected, with the loose finish becoming fed right into a slim space in between the music group as well as the captive attach. If the screw is turned, it works as a worm push tugging the threads in the music group, causing the music group to tighten across the garden hose (or when attached the exact opposite path, to release). Screw clamps are typically utilized for hoses 1/2 ” size and up, along with other clamps used for smaller sized hoses.

The first patent to get a worm-drive garden hose clamp was given to Swedish inventor Knut Edwin Bergström in 1896 Bergström founded “Allmänna Brandredskapsaffären E. Bergström And Co.” in 1896 (ABA) to produce these worm equipment clamps.

Other names for your worm gear hose clamp consist of worm push clamp, worm gear clips, clamps, band clamps, hose clips, and genericized brands such as Jubilee Clip.

Numerous public companies sustain garden hose clamp standards, like Aerospace Sectors Association’s Nationwide Aerospace Specifications NAS1922 and NAS1924, the Society of Car Engineers’ J1508, and so on.

Sets of screw clamps on a brief rubber tube form a “no-center music group,” frequently employed for attaching sections of household wastewater piping, or utilized for other pipes as being a flexible coupler (to repair positioning issues or to prevent pipe breakage as a result of relative motion of parts) or even an unexpected emergency repair.

They can also be employed in a comparable way, being a easy path for the transmission of small quantities of power. A quick length of garden hose is clipped among two shafts in which vibration or variations in alignment may be used up through the versatility from the hose. This method is well adapted for mock-ups within a development lab.

This sort of clamp was marketed in 1921 by ex Royal Navy Commander, Lumley Robinson, who founded L. Robinson & Co (Gillingham) Ltd., a business in Gillingham, Kent. The company is the owner of the brand for Jubilee Clip.

Similar varieties of clamps for hoses range from the Marman clamp, which has a attach music group and a solid attach.

Interlocking plastic clamps, in which the large Fin Clip Base is ideal for overlocking and interlocking the jaw for the required tightness.

T clamps are equipped for high pressure pipes and hoses including turbo pressure hoses and coolant hoses for high pressure engines. These clamps possess a small grub screw that draws the 2 halves of the clamp with each other to securely fasten heavy duty hoses.

Spring clamps are usually made from a strip of spring steel, cut so that one side features a slim protrusion dedicated to the final, and the opposite side a set of slim protrusions on either part. The ends of these protrusions are then curved in an outward direction, as well as the strip rolled to make a diamond ring, with the protruding tabs intermeshing. To use the clamp, the exposed tabs are pushed towards one another (typically utilizing pliers), enhancing the size in the diamond ring, and also the clamp is slid on the hose, past the part that will go onto the barb.

The garden hose will then be match to the barb, the clamp broadened once again, slid on the portion of the hose over the barb, then released, compressing the hose onto the barb. Clamps of this design are seldom utilized for higher pressures or large hoses, as they would require unwieldy amounts of metal to produce sufficient clamping force, and be impossible to work with utilizing just hand tools. They may be widely used on car cooling system hoses a number of inches in diameter, as an example of all water-cooled Volkswagen automobiles.

Spring clamps are especially best for confined or otherwise uncomfortable locations where other clip types would require tightening resources applied from slim and maybe inaccessible perspectives. It has created them especially popular for programs like car motor bays and then for obtaining barb connections in Computer water-chilling.

A simple spring clamp, used on an car vacuum garden hose

Another kind of spring clamp, usually only utilized on vacuum hoses, is just a piece of spring metal wire bent into a loop, with the finishes curled to supply manages. These are used comparable to regular spring clamps, but they are just pinched by hand, and provide almost no clamping force. As opposed to attempting to seal a garden hose in to a barb, they just location a slight stress around the hose, helping keep it from sliding off the barb.

Cable clamps

Cable clamps include a bit of heavy cable, usually made from metal, initially bent into a tight U, then created right into a ring form with one finish overlapping another, and lastly the ends bent in an outward direction and reduce. A captive nut is mounted on one finish, along with a captive screw is linked to the opposite end. If the attach is tightened, the overlapped ends from the wire are pushed apart, tightening the wire loop across the garden hose. For an explanation of why this style is used, begin to see the section on sealing the link.

Ear Clamps

Ear Clamps contain a music group (generally stainless) into which one or even more “ears” or shutting elements happen to be formed. The clamp is placed on the end from the garden hose or tube to be connected so when each ear is closed in the base of the ear using a special pincer tool, it completely deforms, pulling the music group, and causing the band to tighten around the garden hose. The size of clamp needs to be chosen to ensure that the ear(s) are almost completely closed on installation.

Other features of this kind of clamp include: slim band widths, intended to supply a concentrated pressure in the garden hose or pipe; and tamper level of resistance, as a result of permanent deformation from the clamp’s “ear”. If closure from the clamp “ear(s)” is carried out to manufacturer’s suggestions, which typically provide for continuous jaw force, the sealing impact will not be unduly understanding of component threshold variations.

Some this kind of clamps function dimples intended to provide a spring impact when the diameter of the garden hose or pipe contracts or increases because of energy or mechanised effects.

A stepless type of ear clamp was designed by Hans Oetiker in Horgen, Switzerland, which removes actions or gaps in the internal circumference of the clamp. This can be believed to offer consistent compression and a 360° seal. This kind of stepless clamps are claimed to become well suitable for applications concerning slim-walled hoses, supposedly with higher retained lots. This suggests they should be regarded as for difficult to seal programs such as molded plastic materials or other less malleable materials, commonly used in the automotive industry.

Other techniques

Various other methods can be employed to attach hoses or tubing, such as pressure fixtures (when a nylon material or smooth steel ferrule is compressed onto the garden hose by the tightening up in the fitting), drive-match fixtures (where the garden hose is placed inside of a compression sleeve, designed in a way that force up against the hose causes the sleeve to tighten up), swage fixtures (when a rigid collar is compressed onto the hose), clamp fixtures (where two blocks are tightened onto the edges in the hose, frequently found on garden hoses), crimp banding (comparable to worm equipment banding but a crimp is used rather than a screw/line), and numerous other people. Nevertheless, these products are not usually known as garden hose clamps.

Uses and programs

Hose clamps are generally restricted to moderate pressures, including these found in automotive and home programs. At higher pressures, particularly with large garden hose dimensions, the clamp would have to be unwieldy in order to withstand the causes growing it without having enabling the garden hose to slip off of the barb or even a leak to form. For these particular high pressure applications, pressure fixtures, thick crimp fittings, or some other styles are usually used.

Garden hose clamps are usually utilized for issues besides their designed use, and they are frequently used as a much more permanent edition of duct adhesive tape anywhere a tightening band around something would be helpful. The screw music group type in specific is very strong, and is also employed for non-plumbing reasons far more than one other types. These clamps can be found performing from ujliie signs to keeping with each other unexpected emergency (or else) home fixes.

Another useful attribute: worm-drive hose clamps can be daisy-chained or “siamesed” to produce a long clamp, for those who have several, smaller than the job demands.

Some things observed put together with garden hose clamps include the tail growth over a GMP Cricket design helicopter, a home made gas scooter, makeshift water pipe hangers, brackets for rooftop TV and shortwave antennas, and virtually any imaginable vehicle body element.

Hose clamps are normally used in the agriculture business as well. They are used on Anhydrous Ammonia hoses and are made from a combination of steel and iron. Anhydrous ammonia hose clamps tend to be cadmium plated to avoid corrosion and rust.
