Quick Filling/Venting Closures - C - 2158-0022

Nalgene® Ported 83B closure features quick disconnect fittings and inside/outside barbed tubulations. Forms a convenient fluid transfer system with the tubing of your choice. Available in 2 IN or 3 IN port styles for 1/4 IN or 3/8 IN tubing. Socket fittings in cap have internal valves that seal when a tubulation fitting is removed so container seal integrity is maintained. Excellent for use in vacuum systems with Nalgene Heavy Duty Carboys and Bottles. Use with Nalgene 180 heavy-wall tubing. Polypropylene closure and fittings, Tetrapolyethylene gasket. NOTE: Not recommended for vacuum use with lighter weight containers. Fitting-to-socket seals will not hold vacuum after multiple autoclavings.
