The Multiquip 2415320S O-Ring STR46SP (Gardner) is a genuine OEM sealing component designed for HTN27K and HTN28K Whiteman ride-on power trowels. This factory-sourced O-ring delivers the correct material grade and compression profile needed to maintain a reliable hydraulic or fluid seal within the trowel's mechanical systems. Sourced directly from Multiquip, part 2415320S ensures an exact dimensional match to the original component it replaces, keeping your machine operating to spec without guesswork.
Key Features
- Genuine OEM Sealing Material — Gardner-spec compound provides the correct durometer and compression set resistance required for this trowel application, preventing premature seal failure.
- Exact Dimensional Match — Manufactured to the original cross-section and diameter specifications, so the O-ring seats fully and seals correctly upon installation without adjustment.
- Confirmed Fitment for HTN27K and HTN28K — Verified for Whiteman ride-on power trowel models HTN27K and HTN28K; always cross-reference your model and serial plate before ordering.
- Preserves System Integrity — A correctly seated O-ring prevents fluid weeping and pressure loss in the affected assembly, keeping the trowel's mechanical functions responsive and consistent during finishing work.
- Direct OEM Sourcing — Supplied under Multiquip part number 2415320S, eliminating any ambiguity about fitment when cross-referencing your parts manual or dealer documentation.
An O-ring is a precision sealing element used to prevent fluid or air from passing between mating surfaces within a mechanical assembly. In ride-on power trowels, O-rings are commonly found in hydraulic circuits, blade pitch control mechanisms, and fluid reservoirs, where maintaining a leak-free seal is essential to consistent machine performance. When an O-ring wears, flattens, or takes a compression set, it loses its ability to seal effectively — leading to fluid loss, pressure drop, or contamination that can compromise the trowel's control and operational accuracy.
