Straight coupling for pipes of the same outside diameter
The coupling body made of PP runs into threads with cap nuts at the ends. At each end of the coupling body a sealing ring made of nitrile rubber is fitted in, which is kept in place by means of an inside cross-grooved press bushing made of acetal resin.
The prepared pipe is slipped into the coupling body and solidly screwed with the cap nut.
A resilient, inside cross-grooved press cone (ferrule) made of acetal resin is slipped on the pipe to be connected in such a way that the pulled through end projects approx. 40 mm.
