The 08-063 is a straight in-line, non-return plastic valve designed for use with 4.8 mm internal diameter washer fluid hose. Supplied as a single unit, it is engineered to prevent backflow within vehicle screen wash systems, maintaining consistent fluid pressure in the supply line and protecting the washer pump from reverse flow.
Constructed from plastic with a straight joint configuration, the valve connects directly into a 4.8 mm ID hose run without the need for additional adaptor fittings. It is rated to a maximum operating pressure of 100-120 kPa, making it suited to the flow characteristics of standard automotive washer pump circuits.
The 08-063 also cross-references with 08-035, meaning it serves as a compatible replacement across both part numbers within this application. This makes it a reliable single-source solution when either reference is required for a screen wash circuit repair or rebuild.
Each 08-063 is covered by a 12-month warranty and is supplied as one unit per order.
