Multiquip EM98263P Cap Filler Pressurized - OEM Replacement Part for Concrete Pumps

The pressurized filler cap maintains proper hydraulic system pressure in Multiquip concrete pumps, preventing contamination and ensuring consistent material flow during pumping operations. This critical component seals the hydraulic reservoir under pressure, protecting internal components from debris and moisture while maintaining the pressure differential required for efficient concrete delivery. A failing or damaged filler cap can lead to pressure loss, contamination of hydraulic fluid, reduced pumping efficiency, and potential system cavitation—especially critical when pumping long distances or working with stiff concrete mixes where valve efficiency is already reduced.

This pressurized filler cap is compatible with the following Multiquip concrete pump models:

• LS-40, LS-40TD, LS-50TD
• LS-60TD
• LS300G
• LS300GK
• LS300P
• LS450
• LS600
• LS600P

Regular inspection of the filler cap seal and pressure relief mechanism helps prevent hydraulic system failures that can lead to costly downtime on job sites. Replace immediately if pressure relief function is compromised or seal shows wear. Genuine Multiquip OEM part, sold by an authorized dealer.
