Dupree Twis-Loc Valve (Manual) with Permanent Outlet Hose

This complete Dupree Valve assembly includes a hub inlet and outlet that mounts in systems using a permanent outlet hose (typically found in over the road coaches).  Used in many MCI bus applications. NOTE: This is a special configuration use on MCI coaches.  Most private coach owners should use the standard Dupree Twis-Loc Manual Valve found here.  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 able to be easily replaced.
