The Multiquip EM23949 is a genuine OEM 4" Discharge Nipple Heavy Duty designed for the LST25 hydraulic-driven concrete pump. As a direct Multiquip OEM replacement, this nipple is manufactured to the same specifications as the original component installed at the factory. Sourced directly through an authorized Multiquip parts channel, the part is confirmed to fit the LST25 series, giving contractors confidence in both compatibility and long-term durability on the job.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for the heavy-duty discharge circuit, ensuring the nipple handles the pressure demands of concrete pumping without deformation or leakage.
- Heavy-Duty Discharge Rating — Built to withstand the abrasive, high-pressure flow of concrete slurry through the 4" discharge line, where inferior materials accelerate wear and cause premature failure.
- Direct LST25 Fitment — Engineered specifically for the LST25 hydraulic-driven concrete pump; threads and dimensions match the OEM discharge assembly for a clean, leak-free connection.
- Critical Flow Integrity — A worn or damaged discharge nipple can cause concrete blowouts, pressure loss, and costly pump downtime; replacing it with the correct OEM part restores full discharge performance.
- Pressure-System Safety — In a high-pressure concrete pumping circuit, using a correctly rated nipple is essential to maintaining safe operating pressure and preventing uncontrolled discharge line failures.
The discharge nipple is a threaded fitting located at the output end of the concrete pump's discharge circuit. It connects the pump body to the delivery line, directing pressurized concrete slurry toward the pour point. Because it sits at a critical junction in the high-pressure flow path, it must maintain a leak-free seal under sustained pumping loads. When a discharge nipple is worn, cracked, or incorrectly sized, the result is pressure loss, material spillage, and potential line separation — all of which interrupt the pour and create safety hazards on the worksite.
