It seals the 4-way valve in the system to prevent fluid or air leaks and to maintain reliable valve shifting and flow direction.
Check your model’s parts list for the 4-way valve assembly and verify that the O-ring reference is 103611. For the 8900 Proportioner, this is the specified packing O-ring.
Replace it if you notice leaks, pressure loss, erratic valve shifting, or visible damage/wear to the seal during maintenance.
Relieve system pressure, disassemble the 4-way valve per manual, clean the groove, install the new 103611 O-ring, lightly lubricate with a compatible lubricant if specified, then reassemble and test at low pressure first.
For best results, use the genuine Graco 103611. Generic sizes/materials may not match the required tolerance or chemical compatibility and could reduce valve life.
