The Multiquip 11128 Drain Plug is a genuine OEM Drain Plug designed for C30HDNI, C30HDN, and HTN series equipment.

Verified fitment includes the C30HDNI Zenith, C30HDNI Precision, C30HDN, and HTN series machines. Keep part number 11128 on hand as a standard service item to avoid unplanned fluid loss or contamination during maintenance.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to original thread pitch and material specifications, ensuring a leak-free seal at the drain point every time.
- Direct Drop-In Replacement — Threads directly into the existing drain port with no reworking of the housing or fittings required.
- Broad Confirmed Fitment — Compatible with C30HDNI Zenith, C30HDNI Precision, C30HDN, C30HDNI, and HTN series Whiteman ride-on power trowel models.
- Prevents Fluid Loss Between Service Intervals — A properly seated drain plug keeps oil or fluid contained, protecting internal components from running dry or becoming contaminated.
- Fluid System Safety — A failed or cross-threaded drain plug can cause sudden fluid loss during operation; replacing with a correct OEM plug eliminates that risk.
A drain plug seals the lowest point of an oil or fluid reservoir, allowing controlled drainage during scheduled maintenance while keeping fluid contained during normal operation. When a drain plug becomes worn, stripped, or cracked, it can leak steadily or fail completely, leading to fluid loss that damages internal components and creates a safety hazard on the work surface. Replacing a damaged drain plug promptly with a correct OEM part like the Multiquip 11128 restores the integrity of the fluid system and keeps the machine operating through its full service interval.
