SureSeal Direct Mount Adapter Ring
Features
Ease of Mounting
- Solid aluminum construction adapts curved or uneven tank roofs to a smooth and flat mounting surface for your device, ensuring top sealing performance.
- Blind tapped holes on the top and bottom of the adapter stop leak paths in their tracks, while simplifying installation.
- Cast-in alignment marks on the 12:1 and 12:2 SureSeal adapters aid in orientation and alignment.
Compatibility
- The SureSeal adapter allows any device with an API 12B/D/F bolt pattern to mount directly to a tank roof, including:
- Series 4000 Marsh Hawk
- 8″ Series 5000 EPRV with 8 API Connection
- 6″ Series 6000 PVRV with 8 API Connection
- Model 500 Lock Down Hatch with 8 API Connection
Oversized ID
- A nearly 9” [229 mm] ID accommodates any device that extends through the tank roof into the tank, such as a Series 4000 Marsh Hawk
Ensures Level Installation
- Venting devices that rely on gravity to reset need to be installed as level as possible.
- The SureSeal adapter ensures level installation for any device on 12:1 and 12:2 pitched tank roofs.
