Description
US Universal claw type quick disconnect coupling for compressed air according to DIN EN 1562 (sometimes also known as crows foot or Chicago couplings).
These couplings are very widely used for compressed air applications in industry and construction all over the world.
This is a "straight through" coupling - when separated the air on both sides is vented to atmosphere so normally the hose should be vented before disconnection.
Supplied with NPT Male or female threads or a hose tail/barb 3/8" to 1" inside diameter hose. All sizes and types have the same head dimensions and are interchangeable.
To connect or disconnect press the two halves together and rotate through 45 degrees.
Each coupling includes a rubber insert and spare rubber inserts can be ordered separately.
A safety pin can be inserted in an aligning channel between the interlocking couplings to stop couplings being twisted apart accidentally. The safety pin must be ordered separately.
The US washer is made from rubber and provides an airtight seal between interlocking couplings. This is achieved by the washer sliding in to a counter bore below the main coupling bore surface and protruding above the face of the main bore to create a seal.
The use of whipchecks (see related products) is recommended when using this type of coupling.
We can also supply custom made air hose assemblies using this type of fitting with optional certificate of test and label with batch number for traceability.
There is also a European style claw coupling which looks similar but is not the same and is not interchangeable - see releated products.
