DISS Female Hex Nut


SKU: DISS Female Hex Nut

The Compressed Gas Association (CGA) developed the Diameter-Index Safety System (DISS) to establish a standard for non-interchangeable, removable connections for use with Medical Gases, Instrument Air, Vacuum (Suction), and WAGD (Waste Anesthetic Gas Disposal). Non-interchangeable indexing is achieved by a series of increasing and decreasing diameters in the components of the connections. These specific diameters act in key-like fashion, so that fittings within the gas service “family” will connect only with their own “family members.”

DISS Hex Nut & Nipple female fittings are available in multiple configurations including 1/8″ and 1/4″ NPT Male and NPT Female as well as 1/4″ and 5/16″ Hose Barbs. DISS Female fittings are available in air, carbon dioxide, nitrogen, nitrous oxide, oxygen, vacuum and WAGD. All fittings are designed and made in America.
