Each DISS connection consists of a Body Adaptor, Nipple, and Nut. The DISS system is utilized on gas pressure regulator outlets, wall outlets, anesthesia equipment, and respiratory equipment.

    Does the material of construction (brass, stainless steel, monel, etc.) change the rated pressure of the specified CGA?
