A complete modular tank lid kit for forecourt suction systems, bringing together the Risbridger RIS-FLANGE lid, suction assemblies, vent, fill and gauge fittings, flexible connectors and associated blanks and adaptors. Supplied with the number of suction assemblies stated in the product name, each complete with a 4 m drop tube and suction deflector.
Quick to assemble and easy to align. Bolted, sealed flange connections allow the modular fittings to be installed using hand tools, without threaded adaptors or thread sealants at the modular interfaces. Each module rotates through 360° for alignment with the incoming pipework before being secured by tightening the flange fixings.
- Simpler installation: coordinated components reduce the number of separate fittings to specify and assemble.
- Fewer potential leak paths: modular flanged connections reduce reliance on threaded joints, while blind tapped fixing holes avoid through-hole leakage paths at the module fixings.
- Accessible line testing: suction and vent flip-over valves provide shut-off/test functionality in accordance with Risbridger's instructions.
- Easier future tank access: flexible connectors allow fixed pipework to terminate outside the lid's diameter, helping keep the lid removable for tank cleaning, inspection, lining and maintenance.
- Adaptable layout: modular fittings can be disconnected and reconfigured using hand tools, within the available mounting positions and chamber space.
Suitable for new installations or replacement tank lids where the tank manway dimensions, fixing pattern and sealing arrangement are compatible.
Sold separately: tank lid-to-tank gasket, lid-to-tank fixing bolts and overfill prevention valve. The fill tee includes the internal overfill-valve hold-down cage; the valve itself is not included.
