The Multiquip 0482201200 Check Valve O-Ring is a genuine OEM sealing component designed for the CP-20H centrifugal pump. As a factory-sourced part, it meets the exact material and dimensional specifications required to maintain a proper seal within the check valve assembly. This O-ring is a direct-fit replacement for CP-20H units, ensuring correct compression and sealing performance without modification. If your pump is showing signs of backflow, pressure loss, or fluid weeping around the check valve, this is the part to reach for.
Key Features
- OEM-Grade Elastomer Compound — Manufactured to Multiquip's sealing material specification, delivering the correct durometer hardness and chemical resistance needed for pump fluid contact.
- Exact Cross-Section and Diameter — Profiles match the check valve bore precisely, seating fully in the groove for consistent compression across the full sealing surface.
- Built for CP-20H Centrifugal Pumps — Confirmed fitment for the STOW CP-20H, so you can order with confidence and avoid the cost of a mismatched seal.
- Maintains Check Valve Function — A correctly seated O-ring holds backflow pressure and prevents fluid bypass, keeping pump output pressure where it needs to be.
- Fuel and Fluid Compatibility — Formulated to resist degradation from the water and pump fluids encountered in dewatering and centrifugal pump applications.
The check valve O-ring creates an airtight, fluid-tight seal within the check valve body, preventing water or fluid from flowing backward through the pump when pressure fluctuates or the pump is at rest. When this O-ring wears, hardens, or takes a compression set, the seal fails — allowing backflow that reduces output pressure and can cause the pump to lose prime. Replacing this small but critical component restores the integrity of the check valve and allows the CP-20H to maintain consistent flow and prime.
