Frequently Asked Questions
Check your unit’s parts list or repair manual. If your assembly references ProConnect® CS Pump Lower (273295), T4 air motor / E1 electric motor configurations, or T1 2:1 Transfer Pump intake repair kits, the 103414 O-ring is typically applicable.
Loss of prime, fluctuating pressure, visible fluid leakage at the lower, or aeration in the fluid stream often indicate a worn or damaged O-ring. Inspect and replace during routine maintenance.
Use only Graco-recommended lubricants or those specified in your model’s manual to ensure material compatibility and proper sealing performance.
It’s commonly sold individually and also included in certain repair kits (e.g., intake valve repair kits). Review the product page or kit contents to confirm quantity before purchase.
Replacement intervals depend on hours of use, material abrasiveness, and maintenance practices. Inspect during scheduled service and replace at the first sign of wear or leakage.
