Photos help with recognition. CA1 is shown with an aftercooler; T29S is a pump-family reference. Confirm the installed pump model and part number.
Model examples come from the RCP User Manual, printed pages 21–29. Confirm your installed pump number, complete compressor model and serial number. If a part is not listed for ordering, its number carries into a parts-help request.
Before you order
Confirm the match before choosing a part.
01Identify your equipment
Check the pump or compressor model and serial number. Units with similar names can use different components.
02Compare the drawing
Match the manual revision and assembly to your compressor or pump. Compare the shape, mounting points, connections and part number on the existing component.
03Check the ordering part
Drawing numbers identify a position in the assembly. Use the listed part number when ordering; some components are supplied in repair kits or have a newer ordering number.
Ask our parts team
Does something look different?
If a parts-book drawing does not match your compressor or pump, contact us before ordering. Send the model, serial number, part number and photos you have so we can help check the fit.
Selecting parts support from an interactive book carries your selected part number into the help request.
