The Multiquip EM509343 Tee Fitting is a genuine OEM component designed for hydraulic-driven concrete pump models including the LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600. Sourced directly from Multiquip, this fitting delivers an exact match to the original specification so it seats and seals the way the machine was built to run. If you are servicing a Mayco concrete pump in any of these series, the EM509343 is the correct replacement to restore the hydraulic circuit to proper working order.
Key Features
- Genuine OEM Construction — Manufactured to the original pressure and thread tolerances required in concrete pump hydraulic systems, ensuring a secure, leak-free connection under working load.
- Direct Drop-In Replacement — Matches the original port configuration and thread pitch of the EM509343 fitting, so installation follows the same procedure as the factory-fitted part.
- Broad LS-Series Compatibility — Confirmed fit for LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600 hydraulic-driven concrete pumps.
- Hydraulic Circuit Integrity — A correctly installed tee fitting maintains proper fluid routing and pressure balance across the pump circuit; a cracked or leaking fitting will cause pressure loss and erratic pump output.
- Pressure-Side Safety — Concrete pump hydraulic circuits operate under sustained high pressure; using a correctly rated OEM fitting reduces the risk of joint failure and uncontrolled fluid release during operation.
A tee fitting is a three-port hydraulic connector that splits or combines fluid flow within the pump's hydraulic circuit. In a concrete pump, it plays a critical role in directing pressurized fluid to the correct actuators and control components that drive the pumping stroke. When a tee fitting cracks, corrodes, or develops thread damage, the hydraulic circuit loses pressure integrity — resulting in weak or inconsistent concrete output, visible fluid leaks, and potential damage to downstream components if left unaddressed.
