⚡ At a Glance
- • Flow Control: One-way design prevents reverse flow while a clear arrow marks correct orientation
- • Best for: Marine, automotive and small-engine low-pressure petrol, diesel and oil systems
- • Not ideal for: High-pressure fuel injection systems or OEM high-pressure lines
Four 8mm aluminium one-way valves supplied with 16 spring hose clamps for secure assembly. Designed to prevent fuel backflow in low-pressure petrol, diesel and oil lines.
Prevent Fuel Backflow - with an 8mm one-way valve
One-way non-return design allows fluid to pass in a single direction while blocking reverse flow, and each valve is marked with an arrow showing correct orientation. Aluminium alloy construction is anodised for corrosion resistance and maintains thread strength for repeated fittings.
Prevents fuel from returning to the tank, protecting upstream components and keeping delivery consistent. Clear orientation marking reduces installation errors during maintenance.
Durable Construction - thanks to anodised aluminium alloy
Aluminium alloy body with an anodised surface provides structural stability and resistance to corrosion in humid or salty environments. High thread strength supports repeated clamp fittings without stripping.
Longer service life in marine and automotive settings reduces the need for frequent replacements. Robust threads hold up under routine maintenance and vibrations.
Fast Fit and Servicing - with included spring hose clamps
Package includes 16 spring hose clamps that secure the hose-to-valve junction and allow quick tightening and release during assembly and disassembly. Four clamps per valve offer redundancy and a firmer hold under movement.
Makes on-boat or roadside repairs quicker and less fiddly, and spare clamps mean fewer trips to the parts shop. Secure clamping lowers the chance of leaks under vibration.
