Product Identity
This Mueller A 00325 flare fitting is a brass coupling designed for refrigeration systems. It connects two 1/4 inch flare ends in a straight line for technicians assembling or repairing HVAC lines.
Installation Check
Verify that both mating lines carry 1/4 inch flare connections before ordering. Confirm the system design pressure does not exceed the 700 psi rating of this coupling. The overall length is 1 3/16 inches, so ensure the available space accommodates this dimension.
Sustained Pressure Behavior
The brass construction resists corrosion during continuous exposure to refrigerants and lubricants. Rated for 700 psi, the fitting maintains a reliable seal under steady operating pressures without the fatigue that can develop in lower-rated components during prolonged service.

Questions about this item
What is included with the Mueller A 00325 flare fitting and what else is needed?
The box contains the brass flare-to-flare coupling only; compatible 1/4 inch flare tubing and flare nuts must be purchased separately.
Which size and pressure rating should I select for a 1/4 inch refrigeration line?
Choose the 1/4 x 1/4 inch connection rated at 700 psi; it matches standard 1/4 inch flare tubing used in HVAC systems.
What does the 700 psi rating mean when the fitting is installed?
It indicates the maximum working pressure the brass coupling can safely hold in a refrigeration circuit without leaking or deforming.
