For hoses and piping, a quick connect fitting, also called a push fitting or Quick Connect Coupling, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves ...
There are many variations in the design of quick couplers. The initial divergence is between those that can pick up any of a range of buckets and attachments by clamping onto the mounting pins for the attachment (known as "pin grabbers" or "pin couplers") and those that work only with buckets and attachments designed to suit that quick coupler (known as "dedicated").
A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars. [2] Gladhand connectors resemble a pair of "hands shaking" when interlocked, hence the name. [1]
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 ...
To release the coupling, it was sufficient to release the locking bar by pulling on a chain or a handle, which released the rotation of the disk hook. The coupler was mainly used on narrow gauge railways of the British colonies, like e.g. the Bauchi Light Railway in Nigeria, Ceylon, Honduras or the Kalka-Shimla Railway in India. [46] [47]
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
A "through-the-lock" tool that is essentially a modified pinch bar, designed to pull lock cylinders out of doors, and thus allow entry for firefighters. Supply line, supply hose, large-diameter hose fire hose, usually larger than 2.5 inches (64 mm) in diameter, used to transport water from one source to another, such as from a hydrant to a fire ...
Like all Janney couplers, the Tightlock is "semi-automatic". The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that ...
