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}}″-inch INST (FETA, only available with 38&nbsp;mm hose tails) and {{frac|2|1|2}}″-inch INST (BS336).

AroundIn 19551959<ref>{{Cite web|url=https://www.hozelock.com/about-us/|title = About Us {{pipe}} 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}}″-inch hoses.

=== 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″2-inch to 12″12-inch.

aA.k.a. TW couplings, or tanker couplings, these were originally defined by DIN 28450, but are now specified by EN ISO 14420-6. The couplings are widely used in the petrochemical, chemical, and food industries.

=== Forestry coupling ===

=== 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&nbsp;mm. Sometimes called a "swift quick release coupling" or "claw coupling".

=== Guillemin symmetrical clutch ===

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.

Guillemin couplings are available in the following sizes (unit: mm):
