Multiquip 1512 Oil Gallon Orifice

The Multiquip 1512 Oil Gallon Orifice is a genuine OEM component designed for a range of Multiquip and Whiteman equipment including C30HDN series concrete pumps, AR13H series asphalt ride-on rollers, and CA4HM walk-behind power trowels. As a direct OEM replacement, the 1512 is manufactured to the same specifications as the original part, ensuring correct flow control and a proper drop-in fit. Verify your model code against the fitment list before ordering to confirm compatibility with your specific unit.

Key Features

• Genuine OEM Flow Calibration — Manufactured to the exact orifice diameter specified for each application, ensuring oil delivery rates stay within the designed operating range for your equipment.
• Direct Drop-In Replacement — Engineered to the same thread form and seat geometry as the original, allowing straightforward installation without additional machining or fitting.
• Broad Multiquip Fitment — Compatible with C30HDN series concrete pumps, AR13H series rollers, CA4HM and CA-4-4H walk-behind trowels, and related Multiquip and Whiteman models.
• Protects Lubrication System Integrity — A correctly sized orifice meters oil flow precisely; a worn or blocked orifice can starve components of lubrication, leading to accelerated wear or overheating.
• Fuel and Fluid System Safety — Correct orifice sizing is critical to maintaining safe operating pressures within the oil circuit; an incorrect or damaged orifice can cause pressure irregularities that affect machine control and safety.

An oil gallon orifice is a precisely dimensioned restrictor fitting installed within a machine's oil supply or lubrication circuit. Its role is to regulate the volume and pressure of oil flowing to specific components, ensuring each area of the machine receives the correct amount of lubrication under varying operating conditions. When an orifice becomes clogged, worn, or is replaced with an incorrectly sized unit, oil starvation or over-pressurization can occur, resulting in premature component wear, overheating, or loss of hydraulic or lubrication function.
