Thetford Toilet Cassette Holding Tank Automatic Tank Vent Seals Information

A seal kit for the Thetford Toilet Cassette Holding Tank Automatic Vent for Thetford toilet waste cassettes balances the pressure within the cassette during filling and emptying.

The Thetford Toilet Cassette Holding Tank Automatic Vent sits on the top of the waste tank on many Thetford cassettes and can be inspected by turning to the left to remove it. Inspect the needle plate, seal, and o-ring for condition whilst ensuring the spring still operates too. If a replacement Thetford automatic vent is required it can be installed by slotting in and turning to the right to engage.
