Application
WESPC 115017581 / 115017541 piston ring sets are designed for Perkins 404D-22 / 403D-15 and 404C-22 / 403C-15 diesel engines respectively. Both sets feature a 3-ring configuration—two compression rings and one oil control ring—engineered to ensure efficient combustion sealing, reduced blow-by, and stable oil regulation. Suitable for compact engine platforms requiring low emissions, reliable performance, and extended service intervals.
Generator sets
Used in 10–40 kVA Perkins-powered generator sets equipped with 403 and 404 series engines. These ring sets maintain consistent compression and oil control, supporting stable output in both portable and standby power systems.
Industrial systems
Applicable to Perkins 3- and 4-cylinder engines installed in compact tractors, hydraulic systems, and construction machinery. Their wear-resistant metallurgy and precision-machined surfaces ensure durability under frequent load changes, start-stop cycles, and moderate thermal stress.
