Model DD - Lip Seal Ring System Brochure

The SYSTEM DD lip seal ring with reinforcing ring (PP) is developed for plastic pipes and fittings made of PP and PVC in compliance with EN 1451-1 and EN 1401-1 and meets the requirements of EN 681-1 WC. The socket dimensions recommended by M.O.L. apply as well as for other pipe systems. The SYSTEM DD seal features two sealing lips which provide double safety. This is a decisive advantage in comparison to conventional single-lip systems, especially in the building sector. Another feature is the reinforcing ring which permits the use of a soft raw material compound and guarantees a firm fit in the socket.
