Dorman 800-994 AC line connector
This Dorman 800-994 connector joins air-conditioning service hoses, gauges or replacement components using a compression-style quick-connect fitting. The aluminium body is sized for 5/16 in hose fittings and suits HVAC or automotive refrigerant equipment used for charging, evacuation and diagnostics. One piece is supplied per set. It is not for buyers who need a threaded flare fitting or a different hose diameter.
Behaviour under repeated service cycles
The aluminium construction resists corrosion from refrigerant exposure during repeated connect and disconnect cycles. Compression sealing maintains integrity without the torque variance that can affect flare joints over time. No tooling beyond the specified compression method is required for each engagement. The fitting is not designed for permanent installation in high-vibration engine mounts without additional support.
Installing the compression fitting
Push the connector onto the prepared 5/16 in hose end and engage the compression mechanism by hand or with the standard quick-connect tool. The most common issue is a leak caused by a damaged or contaminated hose-end sealing surface before installation. Ensure the mating component matches the 5/16 in size exactly. The single-piece pack means a second connector must be sourced separately for a complete hose assembly.

Questions about this item
Does the aluminium connector resist heat when left on a running A/C service hose all day?
The aluminium body handles normal refrigerant pressures and temperatures encountered during charging, evacuation or diagnostic sessions without softening or leaking.
What hose or fitting must I already own for the 5/16 in compression end to seal?
A matching 5/16 in hose or tube with a clean, round compression seat is required; the connector threads on and seals by compressing against that seat.
Will the 5/16 in compression thread mate with older flare fittings still on my gauge set?
No — compression and flare threads are different; this connector only seals against a 5/16 in compression seat, not against legacy flare nuts.
