Mueller Industries A15620 Filter Inline Check Valve 1/4"

The Mueller Industries A15620 is a 1/4” inline check valve that has a filter and a check valve in one assembly. This tiny valve is highly essential in preventing contamination of HVAC systems and in maintaining the correct direction of the fluid. The filter element removes contaminants that may harm or plug other equipment like compressors, pumps, and heat exchangers. These contaminants are thereby kept out of the system, thus prolonging the existence of these essential HVAC components, This check valve functionality ensures that within the system no backflow of fluids can occur.
