Description:
Cam and Groove fittings are made in accordance with EN 14420-7 standards (DIN 2828). They are used for hose-to-hose or hose-to-pipe connections when transferring liquids. These fittings are commonly known as Ever-tite, cam lock fittings or cam lock couplings. Cam lock fittings are suitable for liquids application or dry bulk products, but not recommended for gas and steam application. Cam lock couplings are available in four materials: Aluminium, Steel, Stainless Steel, and Brass. The working pressure for cam lock fittings are up to 250 PSI. Connections of cam lock fittings are available in threaded end (BSP/NPT) or hose shank for different equipment connection. Features:
Operation of Cam and Groove: To make connection, simply slide the Adapter into the coupler and with normal hand pressure, press the cam levers down. Uncoupling is as quick and simple as coupling. Just lift the cam arms and remove the adapter. |
