Key Features
- Genuine OEM Thread Integrity — Machined to the precise 2 1/2 NPT thread specification, ensuring a full-thread engagement and leak-free seal in the pump port.
- Direct-Fit Replacement — Designed to thread directly into the existing port without rework or additional fittings, matching the original installation exactly.
- Broad Mayco Concrete Pump Fitment — Compatible with C30HDNI, C30HDN, C30HDG, C30HDZ, C30HDGA, LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD models.
- Pressure-Rated Port Sealing — Built to withstand the operating pressures of Mayco concrete pump systems, preventing fluid loss and maintaining hydraulic or material circuit integrity.
- Fuel and Fluid System Safety — A correctly seated NPT plug prevents uncontrolled fluid escape at pump ports, reducing the risk of slips, spills, and unplanned pressure loss during operation.
An NPT plug is a threaded closure used to seal an unused or temporarily inactive port in a pump, manifold, or hydraulic circuit. The 2 1/2 NPT thread profile creates a tapered mechanical seal as the plug is tightened, preventing fluid from escaping the port under pressure. In concrete pump applications, a failed or missing port plug can result in material or fluid leakage, loss of system pressure, and potential safety hazards on the pour site. Replacing a worn or damaged plug with the correct OEM part ensures the port is fully sealed to the design specification of the pump.
