This hose fitting has a diameter of 10 mm for all air intake nipples. It ensures a secure separation of the connection and eliminates the risk of unwanted disconnection as well as injuries from hose whip. The safety coupling relieves the connection before separation, allowing for one-handed operation with minimal effort during coupling and uncoupling. It also prevents loud popping sounds during the coupling process, making it easier to operate even while wearing gloves. The product is made of brass and is nickel-plated, featuring a coupling socket for types 1, 2, 3, and 4. The surface is nickel-plated, the net weight is 0.13 kg, and the temperature range is between -15 °C and 80 °C.
