The Multiquip 50440 is a genuine OEM O-Ring designed for a wide range of Multiquip equipment including MVH308DZ and MVH408DZ reversible plate compactors, QP2TZ and QP3TZ trash pumps, and RW1404MR and RW1504HF rollers. As a factory-sourced component, this O-Ring is manufactured to the exact material grade and dimensional tolerances specified by Multiquip, ensuring a proper seal every time. Verified compatibility covers MVH308DZ, MVH408DZ, QP2TZ, QP3TZ, RW1404MR, and RW1504HF units — confirm your model code before ordering. DHS Equipment stocks genuine Multiquip parts so you can get the right component and get back to work.
Key Features
- Genuine OEM Sealing Material — Manufactured to Multiquip's exact compound and durometer specification, ensuring the correct compression and fluid compatibility for each application.
- Drop-In Dimensional Fit — Matches the original groove diameter and cross-section precisely, seating flush without trimming, stretching, or shimming.
- Broad Verified Fitment — Compatible with MVH308DZ, MVH408DZ, QP2TZ, QP3TZ, RW1404MR, and RW1504HF equipment; always verify your model code against the fitment list.
- Leak-Free System Integrity — A correctly installed O-Ring maintains hydraulic or fluid pressure where it belongs; a worn or cracked O-Ring allows leaks that accelerate wear on surrounding components and cause unplanned stoppages.
- Fluid-System Safety Assurance — On pump and hydraulic applications, a properly rated seal prevents fluid escape that can create slip hazards or contaminate the work area.
An O-Ring is a precisely sized elastomeric seal fitted into a machined groove to prevent fluid or air from passing between mating surfaces or along a shaft. In plate compactors, trash pumps, and rollers, O-Rings are found throughout hydraulic circuits, pump housings, and fluid reservoirs — anywhere a pressurized or liquid-carrying joint must remain leak-free. When an O-Ring hardens, cracks, or deforms with age and heat, the seal fails, causing fluid loss, pressure drop, and potential damage to components downstream; replacing it promptly with a correctly spec'd part restores full system integrity.
