Includes A Pair of 3/4" PVC Tubes, A Pair of large Black Nuts, and A Pair of Gaskets ( part # 54f ).

Commonly used with Autotrol 155 and 255 By Pass valves.
Alternate part # 1001613


Note: In newer Autotrol manual's they call these adapters "CPVC", but they really only fit PVC pipe sizes.
They ( Autotrol ) does not have any for CPVC size adapaters.
This is a grave inaccuracy in their manual's parts listing.
If you have CPVC pipe, then you will need to use a PVC to CPVC adapter or bushing, ( available from any plumbing supply outlet ).
