Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing.  They offer quick, reliable connections, easy implementation, a variety of fitting options and feature amazing versatility.  They’re also, generally speaking, very well priced.  DuoTights are push to connect fittings and require no tubing clamps.

DuoTights are… awesome.  Check out my extensive Hands on Review

DuoTight Fittings have a collar that’s engaged and disengaged to connect and remove tubing without tools or clamps.  That collar can accept a locking clip to prevent the connection from disengaging.  These are not required for a solid connection and are not part of the official DuoTight lineup.
