The Multiquip 910030018 Bonded Seal Washer MQC-100,180 is a genuine OEM component designed for the MQC-100 series concrete pump. This is a direct OEM replacement sourced through Multiquip's authorized parts program, so you can install with confidence knowing it meets the same specifications as the original. Verified compatible with the MQC-100 concrete pump, this washer is the correct part to use when servicing hydraulic fittings, drain ports, or fluid system connections on that machine.
Key Features
- OEM Sealing Material Grade — Genuine bonded seal construction combines a steel outer ring with a vulcanized elastomer insert, delivering the compression and chemical resistance required in concrete pump hydraulic and fluid systems.
- Drop-In Installation — Sized and profiled to seat correctly in the original port or fitting without reworking the mating surface, making service straightforward.
- Confirmed Fitment for MQC-100 — Validated for the Multiquip MQC-100 cycloidal-drive concrete pump series, eliminating guesswork when ordering for that machine.
- Leak Prevention at Fluid Connections — A correctly seated bonded seal washer maintains a pressure-tight joint; a worn or damaged washer can allow hydraulic fluid or oil to weep past the fitting, leading to contamination and pressure loss.
- Genuine Multiquip Part — Supplied as an authentic OEM component under part number 910030018, ensuring traceability and consistency with Multiquip service documentation.
A bonded seal washer — sometimes called a Dowty seal or bonded washer — is a sealing fastener used at threaded hydraulic or fluid ports. It works by compressing the elastomer ring between the fastener face and the mating surface as the fitting is tightened, creating a leak-free seal without thread sealant tape or compound. On a concrete pump like the MQC-100, these seals are used throughout the hydraulic circuit and fluid drain points; when they harden, crack, or extrude from age or over-torquing, the joint can weep fluid under pressure. Replacing the washer with the correct OEM part restores the seal geometry and keeps the hydraulic system operating at rated pressure.
