Fittings, Cylinder Connections

Description
	The standard cylinder connections listed below convert cylinder valve outlets to 1/8"NPT male or 1/4"NPT male.
	Matheson recommends dedicating equipment to a particular gas service. If changing the gas service of regulators is required, the regulators must be thoroughly cleaned and reconditioned. This is very important. It is strongly recommended that regulators be sent to Matheson for conversion to insure safe and dependable operation.
