Hose Coupling - China Amd Notebook Computer - Touch Screen Tablet Pc Types
Air King
The "Air King" Universal Air Hose Coupling (see Dixon Valve) is malleable iron or brass "quarter turn" "sexless coupling" usually found on pneumatic tools like jackhammers. The fitting is considered "universal" because a common two lug head is used on all sizes ranging from 1/4" through 1".
Cam and groove
A 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 most commonly found in petroleum or chemical[ambiguous] applications.
Ground joint
A "Boss" Ground Joint Coupling valve hose coupling is primarily used for compressed air or compressed 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.
Storz
Storz connection on a standpipe.
A Storz coupling is a "quarter turn coupling", or "sexless coupling", commonly used to connect to fire hydrants, easy to connect, no particular male or female end, lugs are on inside of coupling. The standard coupling on fire hoses in Germany.
Guillemin symmetrical clutch
The Guillemin symmetrical clutch is widely used in France and in Belgium by firefighters to couple fire hoses. It is also commonly known under the name of DSP connector.
It can be fastened by hand, but it is also possible to use a tricoise wrench. It is also "quarter turn" and "sexless" (symmetrical).
Each end has a ring with two protuberances outside; when the ring turns, the protuberances lock to the hook of the other hose.
Barcelona
Spanish fire hose coupling.
It is the coupling used by the Spanish firefighters. It is a "sexless" coupling with 3 engaging lugs.
Nakajima
A "quarter turn" or "sexless" coupling used on fire hoses in Japan.
Gost
A "sexless" coupling used on fire hoses in Russia.
Machino
A quick connect and disconnect coupling used on fire hoses in Japan.
NST

National Standard Thread (NST), also known as National Hose thread (NH). The most common type of fire hose coupling used in the USA. The male and female straight (non-tapered) threads screw together and the connection is sealed with a gasket.
Expansion Ring
A Expansion Ring Fire Hose Coupling (see Red Head) is commonly used on lay flay fire hose, it has the advantage of providing no flow restriction, as the expansion ring is expanded to match the inner diameter of the hose. They are installed with special machinery using a drawbar expander. In the USA it is most commonly supplied with NST (NH) threads.
Holedall
Mulconroy
Mulconroy/Holedall Swaged Hose Coupling (see Dixon Valve) is commonly found on larger diameter hoses used in higher pressure applications or where the hose is exposed to higher end pull (i.e, Oil Suction & Discharge (OS&D) hose). They are installed with special hydraulic ram machinery and special dies.
IX
Holedall IX Internally Expanded (Internally Swaged) Hose Coupling (see Dixon Valve) Used in higher pressure applications, or where the hose is exposed to higher end pull, or where a full flow is required. They are installed with special hydraulic pull bar machinery using special pull plugs.
Scovill/Rostra
Holedall (Scovill/Rostra) Internally Expanded Hose Coupling (see Dixon Valve) Used primarily on fuel oil hose applications, where a full flow is required. They are installed with special hydraulic pull bar machinery using special pull plugs. =
