Dupree Twis-Loc Valve

The Dupree Twis-Loc valve was originally developed and marketed as the Owens Valve in 1964, and it has been in production ever since. The Twis-Loc Valve has been installed by many manufacturers during this time such as, Airstream, SilverStreak, Bluebird, Newell and numerous other bus and recreational vehicle manufactures.  The Twis-Loc's significant feature is its certainty of operation and valve position with all parts being easily replaceable.
