A compact one-way valve for fuel and low-pressure lines, designed to prevent backflow and keep systems primed, Jesiah One-Way Fuel Check Valve. Peace of mind for DIY mechanics and marine owners who need a corrosion-resistant, easy-to-fit part. Is it the straightforward fix for common fuel-line problems?
⚡ At a Glance
- • Flow Control: Clearly marked arrow guides installation so fluid moves only in the intended direction
- • Best for: Home mechanics, boat owners and technicians working with low-pressure fuel systems
- • Not ideal for: High-pressure fuel injection systems or applications above typical low-pressure ranges
One-way chrome aluminium check valve suited to 8mm tubing for petrol, diesel, oils and water. Inline fit commonly used in carburettors and other low-pressure fuel systems.
Preventing Fuel Backflow - thanks to one-way internal design
Internal one-way construction allows flow only in the direction of the marked arrow and blocks reverse flow when pressure reverses. Designed specifically for low-pressure fuel lines and related systems.
Keeps fuel in the correct part of the line so tanks do not siphon back and lines remain primed, reducing start-up issues and engine hesitation.
Corrosion Resistance - with chrome aluminium alloy construction
Made from chrome-plated aluminium alloy rather than standard plastic, offering greater resistance to environmental wear and exposure to fuels and moisture. Metal construction improves mechanical durability under routine use.
Holds up better in marine and automotive conditions, lowering the chance of early failure and reducing the need for frequent replacement.
Quick Fit for Common Lines - thanks to 8mm hole diameter
Specified hole diameter of 8mm (5/16") matches widely used tubing sizes, allowing straightforward inline installation without special adaptors. Straight slip-fit connection creates a secure interface for low-pressure applications.
Fast installation into standard 8mm fuel and vacuum hoses, ideal for carburettors, vacuum lines and routine maintenance tasks.
