Cylinder Connections

Connect gas handling equipment to cylinder valves

Cylinder connections are used to link gas handling equipment (such as regulators or transmission piping) to the outlet of a semiconductor/high purity cylinder valve. These connections generally feature particular sizes and thread types to ensure the safe and efficient delivery of gases to the intended equipment. FITOK offers a wide range of cylinder connection series, with different connection designs and standards tailored to various gas types and application requirements. FITOK also provides complete cylinder connection kits, which include fittings, nipples, nuts, adapters, plugs, caps, and gaskets in materials such as nickel, PCFE, PCTFE, and others.

 

To better serve semiconductor clients, FITOK offers cylinder connections that comply with CGA, CGA DISS, and DIN standards, giving customers a variety of options.
