DISS (Diameter Index Safety Standard) cylinder connections are used in the Semiconductor Industry where the highest levels of purity and the lowest leak rate connections are required. Standard DISS connections are available in models that connect to the cylinder and convert to 1/4” MPT. All connections are made from 316L stainless steel and are supplied with a nickel sealing gasket.
