The Multiquip 23966 is a genuine OEM straight barb reducer fitting 5/16 to 3/16 designed for MD80 and HHNG5 series ride-on power trowels. As a direct Multiquip OEM part, it meets the exact material and dimensional specifications of the original component installed at the factory. This fitting is confirmed compatible with MD80 mid-sized hydrostatic trowels and HHNG5 Whiteman ride-on power trowels, making it straightforward to source the correct part for your machine. DHS Equipment stocks genuine Multiquip parts so you can get the 23966 back on the job without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact barb geometry and material grade, ensuring a secure, leak-free connection between hose lines of differing inside diameters.
- Correct 5/16 to 3/16 Reduction — Steps down from a 5/16-inch barb to a 3/16-inch barb in a single inline fitting, eliminating the need for adapters or makeshift solutions.
- Direct-Install Compatibility — Engineered as a drop-in replacement for MD80 and HHNG5 ride-on trowels with no reworking of existing hose routing required.
- Maintains Hydraulic Circuit Integrity — A properly seated barb fitting keeps fluid flowing at the correct pressure and volume; a cracked or loose fitting can cause pressure loss that disrupts blade pitch control and drive response.
- Fuel and Fluid System Safety — Correctly rated barb fittings in hydraulic and fuel lines prevent seepage that could create a fire or contamination hazard on a working trowel deck.
A straight barb reducer fitting transitions fluid flow between two hose lines of different internal diameters within the same run, maintaining a continuous sealed path without requiring a 90-degree change in direction. On ride-on power trowels like the MD80 and HHNG5, these fittings appear in hydraulic control circuits and fuel routing where hose sizes must be matched at a junction point. When a barb fitting cracks, loosens, or corrodes, the resulting leak can starve downstream components of fluid pressure, leading to inconsistent blade response or engine fuel delivery issues that take the machine out of service.
