A 2 in hose clamp (hose clip, hose lock or Jubilee clip (UK)) is a device used to affix and seal a hose onto a fitting such as a barb or nipple. Many kinds can be purchased, such as :
Attach/music group (worm equipment) clamps
Attach clamps include a music group, frequently galvanized or stainless, into that your attach line design has been reduce or pressed. One end of the band includes a captive attach. The clamp is defined round the hose or pipe to become linked, with the loose end becoming provided into a narrow space involving the music group and also the captive attach. Once the attach is turned, it works as a worm push tugging the threads in the music group, causing the music group to tighten up round the hose (or when screwed the opposite path, to release). Attach clamps are typically utilized for hoses 1/2 inch size or higher, with some other clamps used for smaller sized hoses.
The first patent to get a worm-push hose clamp was granted 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 brands for your worm gear hose clamp consist of worm drive clamp, worm gear clips, clamps, band clamps, garden hose clips, and genericized brands like Jubilee Clip.
Numerous public organizations maintain garden hose clamp standards, including Aerospace Sectors Association’s National Aerospace Standards NAS1922 and NAS1924, the Society of Automotive Engineers’ J1508, and so on.
Pairs of screw clamps on the short rubber tube form a “no-center music group,” frequently employed for attaching parts of domestic wastewater piping, or employed for other pipes as being a versatile coupler (to fix alignment issues or prevent water pipe breakage due to relative movement of sections) or even an unexpected emergency repair.

They can also be used in a similar way, as being a simple method for the transmitting of small amounts of power. A brief period of garden hose is clipped among two shafts in which vibration or variations in alignment may be used up from the flexibility in the garden hose. This technique is well tailored for mock-ups in a development lab.
This kind of clamp was marketed in 1921 by ex Royal Navy Commander, Lumley Robinson, who founded L. Robinson & Co (Gillingham) Ltd., a company in Gillingham, Kent. The company owns the trademark for Jubilee Clip.
Comparable varieties of clamps for hoses include the Marman clamp, which features a attach music group as well as a strong screw.
Interlocking plastic clamps, where big Fin Clip Base is made for overlocking and interlocking the jaw for the required tightness.
T clamps are designed for high pressure pipes and hoses including turbo stress hoses and coolant hoses for high stress engines. These clamps possess a small grub screw that draws the 2 halves from the clamp together to securely fasten heavy-duty hoses.
Spring clamps are typically made from a strip of spring metal, cut so that one part features a narrow protrusion centered on the conclusion, and also the other part a couple of slim protrusions on either side. The ends of these protrusions are then bent in an outward direction, and the strip rolled to make a ring, using the protruding tabs intermeshing. To utilize the clamp, the uncovered tabs are pressed in the direction of each other (usually utilizing pliers), improving the size of the diamond ring, and also the clamp is slid onto the garden hose, beyond the part that can go onto the barb.
The garden hose will then be fit to the barb, the clamp broadened again, slid to the area of the hose on the barb, then launched, compressing the hose onto the barb. Clamps of the style are rarely used for high pressures or large hoses, since they would need unwieldy quantities of metal to produce sufficient clamping force, and be impossible to work with using just hand tools. They may be commonly used on car cooling system hoses several inches in size, as an example of all water-cooled Volkswagen vehicles.
Spring clamps are particularly designed for confined or otherwise awkward locations in which other clip types would require tightening up resources used from slim and possibly hard to get at perspectives. It has created them especially popular for programs like automotive engine bays and then for obtaining barb contacts in PC water-chilling.
An easy spring clamp, used on an car vacuum hose
Another type of spring clamp, typically only applied to vacuum hoses, is just a piece of spring steel cable bent into a loop, using the ends curled to provide manages. They are utilized much like standard spring clamps, but they are just pinched by hand, and offer very little clamping force. As opposed to attempting to seal a garden hose in to a barb, they just location a slight pressure around the garden hose, assisting to ensure that it stays from slipping off of the barb.
Wire clamps contain a piece of weighty cable, typically made of steel, first curved right into a tight U, then formed in to a ring shape with one finish overlapping the other, lastly the ends bent in an outward direction and reduce. A captive nut is mounted on one finish, as well as a captive screw is attached to the opposite end. When the screw is tightened, the overlapped ends of the wire are pushed aside, tightening the wire loop around the hose. For the explanation of why this design can be used, begin to see the section on sealing the link.
Ear Clamps contain a music group (usually stainless-steel) into which one or even more “ears” or shutting components happen to be created. The clamp is placed within the end of the hose or tube to become linked and once every hearing is shut at the base in the ear with a unique pincer device, it permanently deforms, tugging the band, and causing the music group to tighten round the hose. How big clamp needs to be chosen in a way that the hearing(s) are almost completely closed on installation.
Additional features of this kind of clamp consist of: slim band widths, intended to supply a concentrated pressure from the hose or pipe; and tamper level of resistance, due to the permanent deformation in the clamp’s “ear”. If closure in the clamp “ear(s)” is carried out to manufacturer’s recommendations, which typically offer continuous jaw force, the sealing impact is not unduly understanding of component tolerance variations.
Some such clamps function dimples designed to supply a spring effect once the diameter in the hose or tube contracts or increases because of energy or mechanical results.
A stepless form of ear clamp was invented by Hans Oetiker in Horgen, Switzerland, which eliminates actions or spaces around the inner circumference of the clamp. This is said to provide consistent pressure and a 360° seal. Such stepless clamps are claimed to get well suited to programs involving thin-walled hoses, supposedly with greater retained loads. This indicates they should be considered for hard to seal applications including molded plastic materials or other less malleable materials, frequently used inside the car industry.
Various other methods can be utilized to attach hoses or tubes, including compression fittings (when a nylon or smooth steel ferrule is compressed onto the hose by the tightening up of the fitting), push-match fittings (in which the hose is inserted on the inside of a pressure sleeve, designed in a way that force against the hose triggers the sleeve to tighten up), swage fixtures (in which a stiff collar is compressed onto the hose), clamp fixtures (in which two obstructs are tightened to the sides in the garden hose, often found on garden hoses), crimp banding (comparable to worm equipment banding but a crimp is utilized instead of a screw/line), and a variety of others. Nevertheless, these devices are certainly not typically called hose clamps.
Utilizes and programs
Hose clamps are typically limited to moderate demands, such as these found in automotive and home applications. At higher pressures, particularly with big garden hose sizes, the clamp would have to be unwieldy to be able to withstand the forces expanding it without enabling the garden hose to slip off the barb or perhaps a leak to form. For these high-pressure programs, pressure fixtures, thick crimp fixtures, or some other styles are usually utilized.
Garden hose clamps are usually utilized for things besides their designed use, and they are frequently used as being a more permanent edition of duct tape wherever a tightening music group around some thing will be useful. The attach band type in particular is quite strong, and is employed for low-plumbing reasons way over another kinds. These clamps can be found doing anything from ujliie indicators to holding together unexpected emergency (or otherwise) home repairs.
An additional handy attribute: worm-drive garden hose clamps can be daisy-chained or “siamesed” to create a long clamp, for those who have several, smaller than the work requires.
Some things seen assembled with hose clamps include the tail boom on a GMP Cricket model chopper, a home made gas scooter, makeshift water pipe hangers, mounts for rooftop Television and shortwave antennas, and virtually every imaginable automobile entire body element.
Hose clamps are normally found 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 avoid rust and corrosion.
