=== Ground joint ===
A "boss" ground joint coupling [[valve]] hose coupling, primarily used for [[compressed air]] or [[steam]]. It consists of a stem, wing nut and spud. It seals as a soft copper seat located in the spud is drawn against the stem by tightening the wing nut.

{{Main|Cam and groove}}
A camlock, also called [[cam and groove]], is a [[quick connect]] [[fluid transfer]] hose coupling that consists of a male "adapter" and female "coupler". The adapter has a groove on the outside that is engaged by the "cam arms" on the outside of the coupler to effect a seal against the [[gasket]] inside the "coupler". They are commonly used for petroleum or chemical applications. Specified by Mil-C-27487 / A-A-59326A / EN 14420-7 / DIN 2828.
Line 49:
Similar in appearance to Bauer couplings, but not compatible with them. Used in agricultural, irrigation, cleaning, and construction industries, but most commonly for water, mortar, bitumen, and bulk products.

Also called [[John Morris and Sons Salford|John Morris Coupling]], BS336 Instantaneous fire couplings are similar in design to the camlock fittings, and are used by; UK, Irish, New Zealand, Indian & Hong Kong fire brigades. They are available in two sizes: {{frac|1|1|2}}″ INST (FETA, only available with 38 mm hose tails) and {{frac|2|1|2}}″ INST (BS336).
[[File:Gardena hose pistol.jpg|thumb|Hozelock-compatible garden hose couplers (Gardena brand)]]
=== Hozelock ===
In 1959<ref>{{Cite web|url=https://www.hozelock.com/about-us/|title = About Us | Our History, Values and Innovations Hozelock Ltd}}</ref> [[Hozelock|Hozelock Ltd]] in the United Kingdom invented and patented the international standard plastic, click-on style, push-fit hose end connector now used with garden hoses. The concept was developed to replace metal hose end connectors in coal mines, which were prone to cause static sparks and the possibility of methane gas explosions. All-metal versions of the connector (and compatible with the plastic versions) are now in common use for garden hoses. The system is now universally used by gardeners throughout the world. The Hozelock brand adapters are typically available with [[British Standard Pipe|BSP threads]], while the compatible Gardena brand, sold mostly in the U.S., uses ¾-11.5NH ([[Garden hose thread]]) threads. There are two different sizes of the connectors available, with the larger one being rare and mainly used on {{Frac||3|4}}″ hoses.
[[File:Perrot-Kupplung.jpg|thumb|Perrot-brand Bauer-style hose couplings]]
=== Leverlock ===
A cam and lock-like coupler, used in the agricultural industry. Also known by the brand names of manufacturers, including Bauer, Perrot, and Miller/Ferrari. Available in sizes ranging from 2″ to 12″.
=== Machino ===
A Japanese quick connect and disconnect coupling used on fire hoses in [[Japan]] and defined by JIS B9911;<ref>{{Cite web|url=http://kikakurui.com/b9/B9911-1968-01.html|title=Dimensions of Insert Type Couplings for Fire−Hose}}</ref> available in several sizes: 25A (1″), 40A ({{frac|1|1|2}}″), 50A ({{frac|2|1|2}}″), 65A (2" ), 75A (3″).
Line 70:
A variety of manufacturers sell the same style quick-connect garden hose coupling. The design is similar in concept to the plastic Hozelock design, in that the female coupling has a spring-loaded outside barrel that locks onto the male coupling, but both couplers are usually made of brass and the male coupling lacks the rubber O-ring found on the Hozelock couplers.

Many of these couplings are of the so-called "claw" type.

=== DSP ===
A French hose coupling, compatible with Guillemin couplings, but used for different purposes. Conforms to NF S61-704 and NF S61-705. Available in the following sizes:
* DSP ND 40 Suitable for delivery (pressure) only, not suction.
Line 89:

=== Express coupling ===
[[File:Express.png|thumb|alt=Express coupling|Express coupling]]Very similar in appearance to GEKA couplings, but not compatible with them, because Express couplings have a 41 mm distance between the claws. These are defined by NF E 29-573. Used for both water and air.
=== Forestry coupling ===
Developed by the Canada Metal Company for the Canadian wildfire firefighters in 1977 to overcome issues of snagging and water volume loss associated with the smaller-diameter Storz couplings, these couplings are now specified for use by Canadian, U.S., and Australian wildland fire departments.<ref>{{cite web|title=Common Hose Couplings for Australian AFAC Member Agencies|url=http://www.fire-brigade.asn.au/pdf/common_couplings_paper_1.pdf|accessdate=26 September 2017}}</ref> The coupling design is specified by CAN/ULC-S551-13 (25 mm and 38 mm forged couplers), CAN/ULC-S558-13 (25 mm and 38 mm non-forged couplers), and ULC/CAN-S574 (64 mm forged couplers), as well as USFDA 5100-192 (US Forest Service) and available for use with 19 mm, 25 mm, 38 mm, and 64 mm hose sizes. Note that Wajax Manufacturing submitted a competing design, but was not selected, so referring to these fittings as "Ajax couplers" is incorrect.
=== Geka steam hose coupling ===
This is a sexless quarter-turn bayonet hose coupler, originally manufactured by the Karasto company distinguishable by the gasket profile, which has a flat outer ring enclosing a domed middle section, as well as the distance between the claws being 40 mm. Sometimes called a "swift quick release coupling" or "claw coupling". This is based on the design of the Giersberg fire extinguisher coupling<ref>{{Cite web|url=https://books.google.com/books?id=zTRT16k-CYcC&q=Giersberg+fire+extinguisher+coupling&pg=PA142|title=A record of the International Fire Exhibition exhibition, Earl's Court, London, 1903|access-date=2017-06-09|last1=Sachs|first1=Edwin O.|year=1903}}</ref> (predecessor to the Storz coupling), and was developed by Julius Oehler in the late 1920s, and was patented in 1932.

=== Guillemin symmetrical clutch ===
[[File:Sme brass guillemin.jpg|thumb|alt=Brass Guillemin coupling|Brass Guillemin coupling]]
The Guillemin symmetrical clutch, also called Guillemin coupling, is widely used in [[France]] and in [[Belgium]] to couple hoses and resembles a [[DSP coupling]], which is used in firefighting. It can be fastened by hand, but it is also possible to use a [[Hydrant wrench|tricoise wrench]]. It has quarter-turn closing and is sexless (symmetrical). It may be fabricated from aluminum, stainless steel, brass or polypropylene. The standard for this kind of coupling is EN14420-8/NF E 29-572, and there is a special standard DIN14420-8 for unique assemblies with ferrule and safety clamp.
