The Multiquip 020PX400008 O-Ring is a genuine OEM sealing component designed for the PX400 series submersible pump. As a direct OEM replacement, this O-Ring is manufactured to the exact material and dimensional specifications required by Multiquip, ensuring a proper seal every time it is installed. Verify your model code against PX400 to confirm compatibility before ordering.
Key Features
- OEM-Grade Seal Material — Manufactured to Multiquip's exact compound and durometer specifications, delivering the compression and chemical resistance required in submersible pump applications.
- Drop-In Installation — Dimensioned to seat correctly in the original groove without trimming or stretching, making replacement straightforward during routine service.
- PX400 Fitment — Confirmed fitment for the Multiquip PX400 submersible pump series, so you can order with confidence knowing this is the right part for your machine.
- Leak Prevention — A correctly installed O-Ring maintains the internal pressure boundary of the pump housing; a cracked, swollen, or flattened O-Ring allows water ingress or pump fluid bypass that degrades output and risks motor damage.
- Genuine OEM Part — Sourced directly from Multiquip as part number 020PX400008, eliminating guesswork on cross-compatibility and ensuring you receive the part the machine was engineered with.
An O-Ring creates a static or dynamic seal between two mating surfaces inside the pump assembly, preventing fluid from bypassing the intended flow path or external contaminants from entering the housing. In a submersible pump like the PX400, a properly functioning O-Ring is critical to maintaining watertight integrity around key joints and ports. When the O-Ring deteriorates — through age, chemical exposure, or compression set — seal failure follows, leading to leaks, loss of pump efficiency, and potential damage to internal components.
