Manufacturer: Total Finishing Supplies
Part Number: 326070
Comparable OEM Part Number: 108690
Description: Total Finishing's part # 43-1540 is a compatible replacement for GRACO® parts 108-690 and 108690 — the u-cup seal used in GRACO® spray equipment. A U-cup is a lip seal shaped like an open channel: system pressure spreads its lips against the rod and bore, so the seal actually tightens as pressure climbs. Compatible with GRACO® EM 5000, GRACO® EuroLiner Trassar 8, GRACO® GM 10 000, GRACO® GM 10000, GRACO® GM 3012, GRACO® GM 5000 and other compatible equipment.
Common reasons for replacement:
- Renewed whenever the assembly is opened for service
- Fluid weeping past the seal under pressure
- Hardened or nicked sealing lips found at teardown
- Pressure loss that tightening does not cure
Manufactured to OEM-equivalent dimensions for proper fit and performance.
