 Using a PVC repair coupling on ABS pipe
Author: ArthurPeabody (NM)

Charlotte Pipe Foundary's instructions for how to install repair couplings:

'Apply heavy body cement (if using PVC) and apply medium body cement (if using ABS) between the mark and pipe end on both pipe ends.'

Since the repair coupling doesn't come in contact with the pipe it couples, does it matter if it's the same stuff? In other words, could I use a PVC coupling (primed) to join 2 pieces of ABS pipe (unprimed) using Oatey's all purpose cement (usable on both PVC and ABS). The only hitch I can see would be that they expand and contract at different rates with temperature. Stores have PVC repair couplings, not ABS.

Use a shielded coupling instead of the repair coupling.

the OP does not know how to slide the shield 'out of the way' onto the pipe, put on the rubber, AND FOLD THE 'OPEN END' OVER ONTO ITSELF for clearance THEN UNFOLD ONTO PIPE after pipes are aligned and then slide shield into place
