Perko Rubber Gasket Kit f/Size 8, 9, & 10 Strainers

The Perko Rubber Gasket Kit f/Size 8, 9, & 10 Strainers is an essential maintenance component for marine and freshwater intake water strainers. This gasket kit restores the watertight seal on Perko intake strainers in sizes 8, 9, and 10, preventing water leakage around the strainer housing cover. If your strainer shows signs of seepage or reduced flow efficiency, worn gaskets are often the culprit—and this kit provides a straightforward, cost-effective solution to extend the life of your existing strainer assembly.

This complete gasket kit includes both a cover gasket and rubber sealing components designed to maintain pressure integrity under operating conditions typical of bilge and cooling systems. The rubber gaskets are engineered to resist saltwater corrosion, UV exposure, and thermal cycling—critical factors in marine environments where gasket degradation accelerates. Perko's rubber formulation ensures consistent compression set performance, meaning the gaskets remain pliable and effective through repeated opening and maintenance cycles. The compact kit (weighing just 0.15 lbs) stores easily and requires no special tools to install, making it ideal for both professional technicians and boat owners performing routine upkeep.

This gasket kit is indispensable for vessel operators who rely on Perko strainers for engine cooling water intake and bilge systems. Compatibility is limited to Perko strainers in sizes 8, 9, and 10 only—verify your strainer size before ordering to ensure proper fit. Installation involves removing the strainer cover, replacing the old gaskets with new ones from this kit, and reassembling the housing with hand-tight fastening. Regular gasket replacement (typically every 2–3 years depending on water quality and usage) prevents corrosion damage to the strainer body and maintains optimal flow rates for critical marine systems.
