4 oz handy size can with brush of all-purpose pipe glue. This all-purpose glue is perfect for ABS, CPVC & PVC. No primer needed when used with black ABS pipe and fittings, but primer is needed when used with white CPVC & PVC pipe and fittings.
Apply liberally to both pipe and fitting. Once applied you have just seconds to push the pieces together. Hold for a few seconds. Bond is permanent. Glued pieces will never be able to be separated.
