ISO FITTING FOR GAS CYLINDER — correct connection from cylinder to equipment
An ISO Fitting for Gas Cylinder connects a cylinder valve to a regulator, hose or manifold, and the right thread and outlet type differ by gas. REAL GAZ helps customers choose connectors that match the gas, the valve outlet and the working pressure.
Using the wrong fitting is not only inconvenient but dangerous, because outlet designs are intentionally different for incompatible gases.
Using the wrong fitting is not only inconvenient but dangerous, because outlet designs are intentionally different for incompatible gases.
Selection is guided by ISO 5145, ISO 15245 and ISO 407 for valve connections, suitable for industrial and medical service.
Outlet systems vary between regions. Flammable gases usually have left-hand threads and oxidising gases right-hand threads, while oxygen, acetylene, hydrogen, nitrogen, argon and carbon dioxide each have their own outlet standard. Never force a connection that does not fit and never use adapters between flammable and oxidising gas outlets. Our team will confirm the correct combination so that fittings, washers and regulators work together.
Maintenance is equally important. Sealing washers harden with age and should be replaced whenever a regulator is refitted, threads should be kept clean and free of grease in oxygen service, and any fitting with damaged threads must be discarded. A quick leak check after every cylinder change takes seconds and prevents waste.
