Allied Medical LLC 12-80-4206 is a high-quality DISS female hex nut and stem assembly designed for secure medical vacuum connections. It features a standardized hex nut that allows for a wrench-tightened connection to vacuum DISS male outlets, transitioning into a 5/16" hose barb for larger diameter flexible suction tubing attachment. This fitting is essential for creating custom hose assemblies used with high-flow suction regulators, collection canisters, and other vacuum therapy equipment where a larger bore is required for efficient fluid management. Its heavy-duty chrome-plated brass construction ensures long-term durability and resistance to the rigors of frequent clinical use. The gas-specific threading ensures that only vacuum-related components can be integrated, maintaining strict clinical safety protocols.
