DORMAN 800-993 AC line connector

The DORMAN 800-993 is an air conditioning line connector built for HVAC technicians and automotive service professionals. It joins service hoses, gauges or replacement components using a compression by threaded design. The 3/8 in fitting size matches common refrigerant line dimensions for charging, evacuation and diagnostics.

Aluminium body resists corrosion

Constructed from aluminium, the connector body is lightweight and resists corrosion in workshop environments. A sealed connection is formed when the included tension ring and seal sleeve are installed within specified service practices. No additional tools are required for the quick-connect function.

Tension ring and seal sleeve included

The package supplies one tension ring and one seal sleeve that work together to create the sealed joint. These components are essential for maintaining system integrity during refrigerant handling. Orders of 75 or more ship directly from the manufacturer.

Questions about this item

How do I install the DORMAN 800-993 connector and what step is often missed?

Slip the tension ring and seal sleeve onto the hose before tightening the threaded end; the seal sleeve must seat fully or the joint will leak.

What parts of the DORMAN 800-993 will need replacement later?

The included seal sleeve and tension ring are single-use items; replace both whenever the line is disconnected for service.

What limit appears first when the DORMAN 800-993 is used continuously?

Repeated connection cycles deform the aluminum threads and compress the seal sleeve, so leak-free performance drops after multiple reassemblies.
