These are devices connected on the end of hoses to couple them to taps, other hoses or hose appliances like irrigation sprinklers. They come in different designs and patterns made out of stainless steel, steel, brass, aluminium or plastic. One made of brass is suitable for joining a hose to another or a type of appliance. The correct selection of these devices is very crucial, and one should consider the hoses to be joined as well as their intended use.
Common Types of Hose Couplings
There are several classifications of Hose couplings, and three well known are; Threaded couplings, Non- threaded gendered couplings and Non-threaded genderless couplings. The Threaded couplings are divided into numerous types which include; Nation Hose Thread, garden hose thread, ground joint, holedall and UNI. National Hose Thread is the most common within the class, and it is usually used with fire hoses.
Like threaded couplers, the Non-Threaded gendered couplers also house several types of couplings with examples like; Camlock, Perrot Cardan, Hozelock, Leverlock, Machino and Tankwagen Flange couplings. The Tankwagen flange couplings. Tankwagen flange is common within the class and is mostly used in the chemical, petrochemical and food industry.
The Non-Threaded genderless couplings are also composed of many types many of which are known as “claw” type. Barcelona, Express couplings, Nakajima, Storz, Air King and Guillemin symmetrical Clutch. The most common within this class are the Storz couplings since little effort is needed for the connection and the “Air King” which are universal air hoses and requires only one air king safety clip for each coupling.
Applications of Hose Couplings
Firefighting.
Slurry industry
Plant hire and construction
Agriculture – irrigation
Cleaning industry
Petrochemical and chemical industry
Food, beverage and pharmaceutical industry
Oil industry
General Overview of Hose Couplings
Mostly, Hose couplings are intended to produce a seal which is airtight and watertight. This makes coupling of hoses an essential procedure industrial application as well as day to day domestic activities like connecting the hoses to gas hose fittings for use in the kitchens.
