CGA-660 Stainless Steel Regulator Nut

The Western Enterprises 312-SS-604 is a new CGA-660 nut machined from stainless steel. It features a 1.035" - 14 NGO right-hand thread and a female connection designed for refrigerant gas regulators. This component provides a secure interface between the regulator body and the gas supply.

For refrigerant systems using CGA-660

This nut suits technicians assembling or servicing regulators for refrigerant gases that require a CGA-660 inlet. It is not for systems using different CGA standards, left-hand threads, or alternative connection types. Builders working with other gas services must source the correct nut for their specific cylinder valve outlet.

Questions about this item

Does the 312-SS-604 nut generate any noise, heat or power draw during continuous use?

No, the stainless-steel CGA-660 nut is a passive mechanical fitting with no moving parts, so it produces no noise, heat or electrical consumption.

What regulator or hose must I already have for this 1.035"-14 NGO RH female nut to connect properly?

You need a CGA-660 male outlet with a matching 1.035"-14 NGO right-hand thread, typically found on refrigerant-gas regulators or pigtail hoses.
