RING-SHAPED FLAT GASKETS FOR PROPULSIVE PIPES

摘要

The specially shaped flat-ring gasket (1) for use with propulsion-type pipes. The gasket (1) comprises an annular cylindrically-shaped flat-ring gasket (1) made of an elastomeric material. Plurality of spaced-apart circumferential bulges (7) of semi-circular cross-section are disposed on the continuous flat-ring gasket and are directed outwardly, with lateral bulges terminating flatly toward the ends of the product. The gaskets are placed on the smooth spigot (2) of the pipe and under pressure are enclosed by the sleeve (4) of the matching pipe. The flat-ring gaskets of this invention provide improved sealings of the propulsion-type pipes.
