COUPLING HIGH PRESSURE - PAM HP FLEX-W4 - NBR - DN500

Code article : 278458

Description

Connection between pipe ends and/or fittingsand accessories from PAM Building, PAM HPFLEX S (W4) couplings withstand up to 10 bar of hydrostatic pressure for most diameters. They are used for straight runs where pressure can occur. 

S (W4) couplings are the most common for HP couplings, they are recommended for inside or outside of the buildings, and for non-aggressive environment. 

EPDM gasket is suitable for most types of effluents, while NBR gasket is recommended for wastewaterand runoff water liable to contain hot oil, solvents orhydrocarbons.
