Key Features
- Genuine OEM Steel Construction — Manufactured to Multiquip's original steel pipe specification, ensuring the same wall thickness, thread pitch, and sealing surface as the part it replaces.
- 3/4 M Pipe Thread Interface — Threaded to standard 3/4 male pipe dimensions for direct installation into the existing port without thread chasing or adapters.
- Broad Trowel Family Coverage — Compatible with BH, BS, HHN, HTX, STX, J, JA, B, BA, CA, PRO, and HDA series models, covering both walk-behind and ride-on concrete finishing equipment.
- Fluid Level Visibility — Provides a clear visual reference for oil level checks during routine maintenance, helping operators confirm correct fill levels before each use.
- Verified OEM Part Number — Ordering by Multiquip part number this part ensures you receive the correct sight glass for your specific trowel configuration.
A sight glass is a small transparent or translucent window threaded into an engine or gearbox housing that allows an operator to check fluid levels at a glance without removing drain plugs or dipsticks. On power trowels, the sight glass is typically used to monitor gearbox oil, which lubricates the blade pitch mechanism and drive components. A cracked, clouded, or missing sight glass makes accurate oil level inspection impossible, increasing the risk of running the gearbox low on lubricant and causing premature wear or seizure of internal components.
