Replacement Lid O-Ring

Suction-side strainer traps rely on an airtight vacuum to effectively pull heavy water loads through filtration channels without introduces air bubbles into your C, CC, or D Series pumps. Because operators frequently pop open the strainer lid to rinse out captured lint, sand, and trash fibers, the sealing ring experiences heavy mechanical flattening, chemical drying, and physical wear. Replacing a stretched or pinched o-ring restores a perfect compression seal instantly, shielding your primary booster pumps from cavitation, erratic pressure readings, or sudden priming failures.

Key features and benefits include:

• Leak-Proof Compression Seal: Restores a airtight vacuum barrier underneath the 8-inch strainer lid, ensuring smooth, uninterrupted water delivery loops.
• Resilient Chemical Resistance: Compounded from heavy-duty rubber engineered to handle continuous exposure to recycled water, surfactant chemistry, and chemical water treatment additives.
• Perfect 8" Casing Fitment: Molded precisely to seat cleanly inside the machined O-ring groove of cast iron strainer housings, avoiding pinching or bunching during lid re-assembly.
• Minimizes Pump Cavitation: Stopping tiny micro-air leaks at the strainer cover protects your pump's internal impellers from micro-implosion erosion and pressure drop-offs.
