The Multiquip 4F15070 is a genuine OEM Cap Master Cylinder Model 10 designed for the TRLR-125XF water trailer. Sourced directly from Multiquip, this cap is an exact OEM component engineered to the original specification for the TRLR-125XF hydraulic brake system. Keeping the master cylinder properly sealed is critical to maintaining hydraulic pressure and brake performance on the trailer, and the part ensures a correct, secure fit every time.
Key Features
- Genuine OEM Sealing Integrity — Built to the original material and dimensional spec for the master cylinder reservoir, ensuring the cap seats and seals as intended without fluid weeping or pressure loss.
- Direct Swap Replacement — Threads directly onto the Model 10 master cylinder reservoir on the TRLR-125XF with no modification to the cap, reservoir neck, or mounting hardware.
- TRLR-125XF Confirmed Fitment — Validated for the Multiquip TRLR-125XF water trailer, so you can order with confidence knowing this is the correct cap for your machine.
- Brake System Protection — A properly seated reservoir cap prevents contamination from entering the hydraulic fluid, which protects the master cylinder bore and downstream brake components from premature wear.
- Safety-Critical Component — The master cylinder cap is part of the hydraulic surge brake circuit; using the correct OEM cap maintains system pressure integrity and supports safe, consistent trailer braking under load.
The master cylinder cap seals the brake fluid reservoir on the TRLR-125XF's hydraulic surge brake system, preventing fluid loss, moisture ingress, and contamination that can degrade braking performance over time. A damaged, cracked, or missing cap allows air and debris into the system, which can cause spongy brake response or accelerated corrosion inside the master cylinder bore. Replacing a worn cap promptly with the correct OEM part keeps the hydraulic circuit sealed and the surge brake system operating as designed.
