Key Features
- Broad Compatibility: Fits hose sizes from 6mm to 12mm — suitable for oil supply joints, hand pumps, oil pumps, water pumps, and aluminium connectors across a wide range of vehicles and machinery.
- Durable Aluminium Alloy Construction: Lightweight yet tough; resists corrosion from diesel, petrol, and general aging, ensuring reliable long-term performance in harsh operating environments.
- Prevents Fuel Backflow: One-way flow design maintains consistent oil pressure and stops reverse flow that can lead to engine cut-out or fuel line seepage.
- Wide Medium Compatibility: Works with diesel, petrol, water, and other non-corrosive liquids. Note: Not suitable for methanol, as it produces formic acid which can corrode internal components.
- Easy Installation: Compact design requires only a spring needle and a wrench — straightforward enough for DIY installation without specialist tools.
- Versatile Applications: Ideal for automobiles (including Peugeot, Renault), motorcycles, boats, ships, helicopters, aircraft, and agricultural equipment fuel systems.
