Fuel Injection Washers
Fuel Injection Washers are critical sealing components designed to ensure a secure, leak-free fit between fuel injectors and the cylinder head, helping maintain optimal combustion efficiency and protect the fuel system from blow-by and carbon build-up. Our range of aftermarket fuel injection washers features high-quality copper injector washers and diesel injection washers from trusted brands such as Laser Tools, known for precision manufacturing and durability. These washers are commonly used in common rail diesel systems and are engineered to withstand extreme temperatures and high injection pressures, providing reliable sealing performance over long service intervals. Available in a wide selection of sizes, thicknesses, and thread diameters including M6, M8, M10, M12, and M14, these fuel injector washers support accurate fitment across many diesel applications. Copper construction allows for excellent heat transfer and malleability, ensuring a proper seal once torqued to specification. Supplied in convenient bulk packs, they are ideal for professional workshops and enthusiasts performing injector servicing, maintenance, or rebuilds. Replacing injector washers during routine injector removal helps prevent fuel leaks, loss of compression, injector knock, and exhaust gas blow-by, ultimately supporting smoother engine operation, improved fuel efficiency, and reduced emissions. As an aftermarket parts supplier, we offer dependable alternatives to OEM injector sealing washers without compromising on quality, making these fuel injection washers a practical and cost-effective solution for maintaining diesel fuel system integrity.
