The Allied 12-80-4235 is a specialized DISS style adapter for medical vacuum systems. It features a hand-tightened winged nut that transitions to a 1/4" hose barb, allowing for rapid, tool-free connection to suction tubing and collection equipment. The white color-coding provides immediate visual identification for vacuum service, ensuring strict adherence to gas-specific safety protocols and preventing accidental cross-connection with pressurized medical gas lines.
