A 1/2 hose clamp (hose clip, hose lock or Jubilee clip (UK)) is a device utilized to affix and seal a hose on to a fitting such as a barb or nipple. Numerous types can be found, such as :
Attach/music group (worm equipment) clamps
Screw clamps include a music group, often galvanized or stainless, into which a screw thread design has become cut or pressed. One finish from the music group contains a captive attach. The clamp is defined across the hose or tube to become linked, with the loose end becoming fed in to a slim space between the band and also the captive attach. When the attach is transformed, it behaves as a worm push pulling the threads from the music group, creating the band to tighten round the garden hose (or when screwed the opposite direction, to loosen). Screw clamps are normally employed for hoses 1/2 ” size and up, with other clamps employed for smaller sized hoses.
The initial patent to get a worm-push garden hose clamp was given to Swedish inventor Knut Edwin Bergström in 1896 Bergström founded “Allmänna Brandredskapsaffären E. Bergström & Co.” in 1896 (ABA) to manufacture these worm equipment clamps.
Other names for that 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 general public companies sustain garden hose clamp standards, like Aerospace Sectors Association’s National Aerospace Standards NAS1922 and NAS1924, the Society of Automotive Engineers’ J1508, etc.
Pairs of attach clamps over a brief rubber tube form a “no-hub music group,” frequently utilized for affixing sections of domestic wastewater piping, or employed for other pipes as being a versatile coupler (to fix positioning difficulties or avoid water pipe damage due to relative movement of parts) or even an emergency repair.

They can be used within a comparable way, as a easy means for the transmitting of small quantities of power. A brief length of hose is clipped between two shafts where vibration or variations in alignment may be taken up from the versatility of the garden hose. This method is well tailored for mock-ups in a development lab.
This type of clamp was promoted in 1921 by ex Royal Navy Commander, Lumley Robinson, who established L. Robinson & Co (Gillingham) Ltd., a company in Gillingham, Kent. The company owns the trademark for Jubilee Clip.
Comparable kinds of clamps for hoses include the Marman clamp, that also includes a attach music group and a strong attach.
Interlocking plastic material clamps, where the large Fin Clip Base is made for overlocking and interlocking the jaw for the needed tightness.
T clamps are designed for high pressure pipes and hoses like turbo pressure hoses and coolant hoses for high stress engines. These clamps have a small grub attach that draws the 2 halves of the clamp together to securely fasten durable hoses.
Spring clamps are typically created from a strip of spring metal, reduce to ensure that one part includes a narrow protrusion focused on the final, as well as the other part a pair of narrow protrusions on either part. The finishes of those protrusions are then curved in an outward direction, and also the strip rolled to form a diamond ring, with the protruding tabs intermeshing. To use the clamp, the uncovered tabs are pushed in the direction of the other person (usually using pliers), enhancing the diameter of the ring, and also the clamp is slid on the garden hose, beyond the portion that will go to the barb.
The garden hose is then match on the barb, the clamp expanded again, slid onto the part of the hose within the barb, then launched, compressing the garden hose on the barb. Clamps with this style are seldom utilized for higher pressures or big hoses, as they would need unwieldy levels of steel to generate enough clamping force, and stay extremely hard to work with utilizing just hand tools. They are commonly used on automotive chilling system hoses a number of inches in diameter, for example on most water-cooled Volkswagen automobiles.
Spring clamps are especially best for confined or else uncomfortable places in which other clip types would need tightening resources used from slim and perhaps hard to get at perspectives. It has created them especially well-known for programs including car engine bays and then for obtaining barb connections in Computer water-chilling.
An easy spring clamp, used on an car vacuum hose
Another kind of spring clamp, usually only utilized on vacuum hoses, is just a bit of spring steel wire bent into a loop, with all the finishes curled to supply handles. They are utilized similar to regular spring clamps, but are just pinched by hand, and offer hardly any clamping force. Rather than trying to seal a garden hose in to a barb, they just place a slight stress in the garden hose, helping ensure that it stays from sliding off of the barb.
Cable clamps consist of a bit of heavy wire, usually manufactured from steel, first bent right into a small U, then created into a ring shape with one end overlapping another, lastly the finishes curved outwards and reduce. A captive nut is connected to one finish, along with a captive screw is linked to the other end. When the attach is tightened, the overlapped ends from the cable are forced apart, tightening up the cable loop round the garden hose. To have an explanation of why this design is used, see the section on sealing the connection.
Ear Clamps consist of a music group (usually stainless-steel) into which one or more “ears” or shutting elements have already been created. The clamp is placed within the finish from the hose or tube to be connected and when every hearing is shut in the base of the ear having a special pincer tool, it completely deforms, tugging the band, and creating the music group to tighten around the hose. The size of clamp should be chosen to ensure that the hearing(s) are nearly completely shut on installation.
Other highlights of this type of clamp include: narrow music group widths, intended to provide a focused pressure of the garden hose or tube; and tamper resistance, because of the permanent deformation in the clamp’s “ear”. If closure of the clamp “ear(s)” is conducted to manufacturer’s suggestions, which typically look after constant jaw force, the sealing effect will not be unduly understanding of component tolerance variations.
Some this kind of clamps feature dimples designed to supply a spring effect when the size from the hose or pipe contracts or expands as a result of thermal or mechanised effects.
A stepless type of hearing clamp was designed by Hans Oetiker in Horgen, Switzerland, which eliminates actions or spaces around the internal circumference in the clamp. This can be said to offer uniform compression and a 360° seal. Such stepless clamps are stated to be well suited to applications involving slim-walled hoses, apparently with higher retained lots. This indicates they must be considered for difficult to seal applications like shaped plastics or any other much less malleable components, commonly used in the automotive industry.
A number of other methods can be utilized to attach hoses or tubing, including pressure fittings (when a nylon material or soft steel ferrule is compressed on the garden hose from the tightening up from the fitted), drive-match fittings (in which the garden hose is placed inside of a pressure sleeve, designed in a way that force from the hose triggers the sleeve to tighten), swage fittings (where a rigid collar is compressed onto the garden hose), clamp fittings (where two obstructs are tightened onto the edges from the hose, frequently found on backyard hoses), crimp banding (comparable to worm equipment banding but a crimp can be used rather than a attach/thread), and a multitude of others. Nevertheless, these devices are not usually called garden hose clamps.
Uses and programs
Hose clamps are typically confined to average demands, including those found in automotive and home applications. At high demands, particularly with large hose dimensions, the clamp would have to be unwieldy in order to endure the causes growing it without having enabling the hose to slip off the barb or perhaps a leak to make. For these high pressure applications, pressure fixtures, thick crimp fittings, or any other styles are normally utilized.
Garden hose clamps are usually used for issues apart from their designed use, and therefore are frequently utilized as being a more permanent version of duct adhesive tape wherever a tightening band around something will be helpful. The screw music group type particular is extremely strong, and is also employed for non-plumbing reasons way over the other types. These clamps can be found performing everything from ujliie signs to holding together unexpected emergency (or else) home repairs.
An additional handy characteristic: worm-drive garden hose clamps can be daisy-chained or “siamesed” to produce a long clamp, if you have several, shorter than the work requires.
A few things observed put together with hose clamps include the tail growth on the GMP Cricket design helicopter, a home made gas scooter, makeshift water pipe hangers, brackets for rooftop TV and shortwave antennas, and virtually every conceivable automobile entire body element.
Hose clamps are generally found in the agriculture industry as well. They are used on Anhydrous Ammonia hoses and are produced from a mix of steel and iron. Anhydrous ammonia garden hose clamps tend to be cadmium coated to stop rust and corrosion.
