<p>Pipe ends are introduced into the sleeve body, at each end of which is a hard, deformable ring with a central bore equal to the pipe o.d., and with a sealing cushion in the zone facing the sleeve, against whose end face it comes to rest, the two having mating taper surfaces. A thin conical metal ring rests against the conical taper surface of the plastics ring and cooperates with a conical rest on the screwed presser element.</p> |
