Complete Propage quick connector ISOCOUPLE with flashback arrestor fitting gas hoses DN 6.3 and DN 10.

In compliance with standards EN 730-1 and ISO 5175-1, this quick connector enables to easily connect or disconnect gas hoses and torches when under pressure, while making it impossible to connect two incompatible gas hoses.
This device is compounded of two elements, one male and one female. The female element is fitted with an automatic shut-off system to prevent gas leakage when the two elements are disconnected.

Combined with a flaskback arrestor preventing both the gas and the flame from going back up and reaching the hose, the regulator or even the gas cylinder, so you can work in complete safety.

Do not set more than two flashback arrestors per flame in-between the torch and the pressure regulator in order to limit pressure loss.
