Rubber hoses General description Structure STENFLEX rubber hoses have been optimized by calculation and verified by experimentation to produce highly elastic, pressure-resistant hoses with the capacity to absorb large movement. Rubber hoses have a three-ply wall structure: ■ inner ply (core) of medium-resistant rubber compound ■ intermediate ply of rubber compound with reinforcement ■ outer ply (hose cover) of weatherproof rubber compound The rubber grades used for the inner and outer ply are empirically defined rubber compounds rated to certain properties. The inner rubber material – the...

Rubber hoses General description Material qualities of hose elements Rubber grade EPDM Ethylene propylene diene rubber Trade name Buna AP Keltan Vistaton Heat-, weather and ozone-proof rubber grade with special resistance to highly oxidizing media and most chemicals (not oilproof). Safe temperature range for continuous operation from -40°C to +110°C. Water, hot water, steam, acids, lye, pickling lye, hypochlorite solutions etc. Perbunan Nitril Oil-proof and fuel-resistant, good physical properties, food-resistant, weather- and ozone-proof, wear-resistant, conditionally resistant to certain...

Rubber hoses General description Connection parts STENFLEX rubber hoses type GSS and GSD consist generally of standard rubber parts clamped to robust connection elements. The following connection parts are possible The extensive compression provides optimum force transfer (high tensile strength). The clamping shells extend beyond the socket and thus protect against buckling. ■ Flanges (rotating flanges or fixed flanges) ■ Threaded connections ■ Combined connections ■ Special connections The readjustable safety hose fitting guarantees a long service life. The connection parts are fitted to...
