Campbell Hausfeld CV220303AJ Barbed Check Valve

The Campbell Hausfeld CV220303AJ barbed check valve is an inline, one‑way valve used in Campbell Hausfeld portable air compressors to prevent reverse flow in the supply line. It features barb fittings for hose connections and is listed in Campbell Hausfeld’s CV2203xAJ valve family as CV220303AJ with a barb fitting, confirming its role in the replacement path for CV220301AJ, CV220302AJ, and CV220303AJ models. Replacement kits such as GR001600AJ identify CV220303AJ as compatible in a 1/2 X 1/2 configuration, underscoring its place in the CV2203xAJ valve lineup. In typical installations, the valve sits in the compressor’s air path to stop backflow and support reliable operation of downstream components like regulators and unloader devices.
