This is a SHORT CGA-320 to 1/4" MNPT stainless steel fitting with included Teflon washer. Nipple length is 1.75 in. This size CGA fitting is used to connect regulators to compressed gas cylinders with a flat gasketed seal and a maximum pressure of 3000 psig. This CGA-320 fitting, PN: SEQ3204SSL, is rated for use with the gases listed below. The Teflon washer is not typically reuseable. See part number P1012970 for replacement washers.

CGA-320 for use with:

CGA fittings are standardized and authorized for the attachment of regulators and transfer lines to gas cylinders filled with specific gases at defined maximum pressures. The three digit number, CGA (XXX), corresponds to the specific gases for which that fitting is tailored (see the downloads).

Connections to cylinders should never be forced. CGA fittings mated between regulator and cylinder never use pipe dope or PTFE tape. CGA connections use either a bullet-nose or gasketed seal. The bullet nose connection has a metal-to-metal contact and seal. Some bullet-nose connections have an o-ring to help improve the seal and to allow a connection to be made without a wrench (hand-tight connections). A gasketd connection requires a flat washer to make the seal. CGA fittings are available in several materials including brass, stainless steel, nickel or chrome-plated brass, and Monel. The CGA fitting material to use depends on the gas and cylinder pressure.
