Product Overview
The unloading elbow is a connection component mounted on petroleum tank trucks to enable safe, efficient bottom unloading of fuel into underground storage tanks. It connects the tanker’s discharge outlet to the station-side adapter at the service station or depot.
Our unloading elbows are designed for quick coupling, tight sealing, and smooth fuel flow during delivery. Operators can visually monitor product movement through an integrated sight glass, which allows them to confirm:
- Whether fuel is actively flowing
- Whether overflow has occurred at the underground tank
Available in various sizes and connection formats, these elbows are compatible with a wide range of fueling systems and help reduce downtime and spill risk during unloading.
Features
- Quick-connect design allows the elbow to be secured by simply pressing it onto the adapter
- Viton lip seal provides reliable lateral sealing even at flow rates up to 1400 L/min
- 360° rotation prevents hose kinking, allowing free product flow and reducing fuel delivery time
- Integrated cast handle offers enhanced durability and safety; its elevated position and lever-based design reduce operating force
- Replaceable inlet connection secured with bolts for easy maintenance—no risk of thread wear
