Grohe ø90 mm Straight Union Connector Pipe — Rapid SL Wall-Hung Frames
A straight ø90 mm union connector pipe for Grohe Rapid SL wall-hung WC frames, art. 42766000. It clips into the frame’s outlet clamp in place of the 90° elbow connector supplied with the frame, so the waste runs straight out horizontally through the wall rather than dropping down or angling off to the side. Black finish, 95 mm long.
Typical job: the soil pipe exits the wall directly behind the frame’s outlet position, so the supplied elbow would point the waste the wrong way — swap it for this straight pipe and run true through the wall. A standard 90 mm to 110 mm adaptor fits straight onto the outlet to take it to 4" (110 mm) soil pipe — use the reducer adaptor supplied with most frames, or any standard 90-to-110 pan connector adaptor.
Not the part for a floor-exit soil pipe — the elbow supplied with the frame covers the drop. And if the wall pipe sits out of line with the frame’s clamp position, you need a stepped offset connector such as the Geberit 50 mm offset set rather than a straight pipe.
