The Multiquip 0489352400 Suction Cover O-Ring is a genuine OEM sealing component designed for QP402B and QP402H centrifugal pumps. As a direct OEM replacement, this O-ring is manufactured to the exact material grade and dimensional tolerances specified for these pumps, ensuring a proper compression fit at the suction cover interface. Verified fitment covers QP402B and QP402H pump models, making it straightforward to confirm you have the right part before ordering. Keep a spare on hand — O-rings are a routine service item on any working pump.
Key Features
- Exact Material and Dimensional Spec — Manufactured to OEM compression and durometer tolerances, delivering a consistent, leak-free seal at the suction cover every time.
- Drop-In Suction Cover Fit — Profiles match the suction cover seat on QP402B and QP402H pumps exactly, seating cleanly without trimming or adjustment.
- Confirmed QP402B and QP402H Fitment — Verified for both the Briggs and Stratton-powered QP402B and the Honda-powered QP402H centrifugal pump models.
- Maintains Prime and Suction Performance — A properly seated O-ring holds the vacuum needed for the pump to self-prime and sustain full flow; a cracked or flattened ring causes prime loss and reduced output.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, so the part number, material compound, and geometry match the original component installed at the factory.
The suction cover O-ring creates an airtight seal between the suction cover and the pump housing, which is essential for the pump to build and hold the vacuum required for priming. Without an intact seal at this joint, air is drawn into the suction side of the pump, causing loss of prime, erratic flow, and potential cavitation damage to the impeller. Over time, exposure to water, debris, and repeated pressure cycles causes the O-ring to flatten, crack, or swell — at which point replacement is the only reliable fix.
