Adapters & ReducersTransition Fittings
316L stainless steel push-fit adapters and reducers step the line between sizes and tie the system into existing pipe of any material through compatible couplings. That makes them the key piece for renovations and mixed-material systems—all with the same lubricate-and-push EPDM join as the rest of the push-fit range.
