The Multiquip 512190 Straight Adapter is a genuine OEM component designed for Whiteman hydraulic power buggies and Essick stationary mixers, including the WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, WBH-21EF, WBH21EPA, WTB-16, PRO12, PRO12E51, PRO12E53, and PRO20. Sourced directly from Multiquip, this adapter carries the same specifications as the original part installed at the factory. Choosing the correct straight adapter ensures secure hydraulic or fluid line connections that hold up under the continuous demands of mixing and material transport applications.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications, ensuring correct thread form, material grade, and sealing integrity for hydraulic and fluid line connections.
- Direct Drop-In Replacement — Machined to match the original port dimensions and thread pitch, allowing the adapter to seat and torque correctly without rework or modification to existing fittings.
- Broad Fitment Coverage — Confirmed for the WBH-16 and WBH-21 series Whiteman hydraulic power buggies, the WTB-16 track buggy, and PRO12 and PRO20 Essick stationary mixers.
- Leak-Free Line Integrity — A correctly fitted straight adapter maintains consistent fluid pressure and flow; a worn or mismatched adapter risks weeping connections, pressure loss, and unplanned downtime in the hydraulic circuit.
- Verified Part Number — Order with confidence using Multiquip part number 512190, cross-referenced against the WBH and PRO series parts documentation.
A straight adapter is a threaded connector used to join two hydraulic or fluid lines in a direct, in-line configuration. In power buggies and mixer hydraulic systems, these fittings route fluid between the pump, motor, and control valves, maintaining the pressure required for consistent machine operation. When an adapter cracks, strips, or fails to seal properly, fluid loss occurs — leading to sluggish hydraulic response, overheating, or a complete loss of drive or mixing function.
