The Multiquip 16569 Dust Cap Parker H4-66M is a genuine OEM component designed for WRS5200DFPU, WRS5200, and WRSPUDF ride-on roller screeds. Sourced directly from Multiquip, this dust cap delivers an exact fit against the original Parker H4-66M specification, ensuring proper protection of hydraulic fittings and ports on your screed. Keeping the correct cap installed on your equipment is a simple but critical step in maintaining the integrity of the hydraulic system between service intervals.
Key Features
- OEM-Grade Sealing Material — Manufactured to the Parker H4-66M specification, providing the compression fit and material grade needed to effectively seal hydraulic ports against contamination.
- Direct-Connect Fit — Threads or seats directly onto Parker H4-66M compatible fittings with no adaptation required, matching the original cap used on the production line.
- Confirmed Fitment — Verified for WRS5200DFPU, WRS5200, and WRSPUDF Whiteman ride-on roller screeds, so you can order with confidence for your specific machine.
- Hydraulic Port Protection — Blocks airborne debris, moisture, and jobsite contaminants from entering open hydraulic ports during storage, transport, or service — keeping your hydraulic system clean between connections.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM replacement, this cap meets the same standards as the component installed at the factory, with part number 16569 confirmed for the Whiteman roller screed lineup.
A dust cap serves as a protective cover for hydraulic fittings and open ports, preventing dirt, moisture, and debris from entering the hydraulic circuit when a line is disconnected or a port is left exposed. On ride-on roller screeds like the WRS series, maintaining clean hydraulic connections is essential — contamination introduced through an unprotected port can cause premature wear in valves, cylinders, and pumps throughout the system. Replacing a missing or damaged dust cap promptly is a low-cost way to protect far more expensive hydraulic components downstream.
