Multiquip EM137 Tee-Slot 3/4-10x14" C30HD - OEM Replacement Part

The tee-slot manifold is a critical flow distribution component in Multiquip C30HD series concrete pumps, directing material flow from the primary valve system through the pump's discharge circuit. This 3/4-10x14" tee-slot assembly sits at the heart of the pump's valving system, working in conjunction with the ball and seat mechanisms to ensure proper concrete distribution and prevent material accumulation that can lead to diminished pump output and the "volcano effect" in the hopper.

During troubleshooting procedures outlined in Multiquip service manuals, inspecting and cleaning the manifold assembly—including the T-manifold (primary distributor)—is essential when diagnosing reduced pump performance. The tee-slot component must maintain proper sealing to prevent air from entering the T-manifold, which can compromise material flow. Regular inspection of this assembly along with the distributor, ball retainer pins, and seats helps prevent blockages that require hose exploration and material removal procedures.

This part is compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
