This cap seals the valve port to prevent refrigerant loss and contamination ingress when the access valve is not in use. It is a direct service accessory used on refrigerant circuit access points in HVAC and refrigeration systems. The 3\/8 inch tube OD sizing makes it compatible with commonly used access valves found in residential and light commercial cooling equipment. HVAC technicians install and remove this cap routinely during system service and maintenance procedures.\u003c\/p\u003e\n\u003cp\u003eThis accessory is suited for residential and light commercial HVAC and refrigeration applications wherever Parker brass access valves are installed. It is typically found on suction and liquid line access fittings used during refrigerant recovery, charging, and pressure testing. The integrated gasket provides a positive seal at the valve cap seat, maintaining system integrity between service visits. Technicians working on split systems, package units, and refrigeration circuits will encounter this type of cap as a standard field component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick seal design allows fast cap installation and removal during refrigerant service\u003c\/li\u003e\n  \u003cli\u003eIntegrated gasket provides a positive seal at the valve port\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8 inch tube OD access valves\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with Parker brass access valves\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.03 pounds per cap\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Parker brass access valves with a 3\/8 inch tube OD port.
