Unlike other coupling designs, the handy WE-ER^® hose fittings require neither use of tools nor hose binding.

After mounting, the WE-ER^® hose coupling will not be further moved. The entire unit is firm on the pipe system or device, thus presenting a significant safety factor in comparison to other coupling systems: Even if the connection tears or comes undone suddenly, no injuries will be caused by any iron parts stuck on the hoses.

The WE-ER^® connection system consciously does without front-end seals which, subjected to friction, frequently cause leaks. In case of the WE-ER^® hose fittings the hose itself functions as seal; clamped correctly tight between the inner parts as well as upper and lower parts of the coupling, a leak-tight fit is guaranteed. The spring tension has been calculated to prevent the coupling from re-opening, once the tension lever has been engaged.

Easy and quick assembly and operation of the WE-ER^® hose fittings, perfect leak-tight connections avoiding costly losses of compressed air lead to a considerable rationalisation: : significant savings in time, labour and cost.
