This handy adapter allows the use of Valterra caps and hose adapters on a Thetford system.  

It has two 3" Thetford hooks on one end to connect to white Thetford bayonets.  On the other end it has four standard 3" Valterra bayonets for attaching a Valterra cap or any of the many Valterra-compatible hoses.

May be made of black ABS plastic or white ABS plastic, depending on batch.
