DISS Nuts

DISS stands for Diameter Index Safety System and was created by the CGA (Compressed Gas Association) to establish a removable, non-interchangeable connection to use for many of your medical gas needs. DISS fittings ensure that the operator does not cross connect fittings and also prevents the mixing of gasses and/or the accidental use of a wrong connection, which ensures patients are kept safe from accidental gas mixes or leaks.
