After the claws are engaged, the locking nut is tightened manually, thereby preventing the connection from coming loose on its own.\u003c\/p\u003e\u003cp\u003eThe coupling has a 42 mm claw spacing with double safety cams. The coupling body is made of galvanized steel\/cast iron, and the locking nut is made of brass. An oil-resistant NBR seal is used. The temperature range is −40 °C to +100 °C, and the maximum operating pressure is PN 16.
