This Connect Assorted Metric Diesel Injection Washer box is designed for mechanics and workshops needing a reliable supply of DIN Standard 7603A washers for diesel injection systems. The primary benefit is the comprehensive assortment covering M6 to M17 sizes, ensuring you have the right part for most common applications. A key consideration is that due to the item's size and weight, special delivery terms may apply, and it is not suitable for casual DIY users.

DIN Standard 7603A refers to a German Institute for Standardization specification for sealing washers, particularly for oil and fuel applications. It ensures a certain level of quality, material, and dimensional consistency for reliable sealing in diesel systems.
These washers are used to create seals in diesel fuel systems, commonly found between fuel injectors, injection pumps, and fuel lines to prevent leaks and maintain pressure.
While they might physically fit, these washers are specifically designed and recommended for diesel injection systems due to the unique pressures and fuel properties involved. Using them in petrol systems may not provide an adequate or durable seal.
Store the box in a clean, dry place away from extreme temperatures and moisture to prevent corrosion and contamination. Keep the lid securely closed when not in use.
No, diesel injection washers are designed to be single-use crush washers. Once installed and tightened, they deform to create a seal. Reusing them can lead to leaks and improper sealing.
The M designation typically refers to the inner diameter, often corresponding to the bolt or fitting size. For precise outer diameter, thickness, and bore dimensions conforming to DIN 7603A, consult a DIN 7603A specification chart.
The product description does not specify the exact material, but washers conforming to DIN 7603A are typically made from copper or aluminum alloys, chosen for their malleability and ability to form a tight seal under pressure.
Ensure the correct washer size and type (M6-M17, DIN 7603A) was used. Verify that the mating surfaces on the component and fitting are perfectly clean, flat, and free from burrs or damage. Check that the component was tightened to the manufacturer's specified torque.
Refer to the service manual for the specific diesel injection component or vehicle model. The washers are organized by metric size (M6 to M17) within the box.
Do not use the damaged washer. Select another appropriate washer from the box. If multiple washers appear defective, check the storage conditions or contact the supplier.
Setup & Use: These washers are designed for direct replacement in diesel injection systems. Ensure the mating surfaces are clean and free from debris before installation. Select the correct washer size (M6-M17) according to the specific requirements of the diesel injection component (injector, pump, or fuel line fitting) you are servicing. Consult the vehicle's or equipment's service manual for precise specifications if unsure.
Compatibility: The washers conform to DIN Standard 7603A, making them compatible with a wide range of diesel injection systems that specify this standard. They are suitable for use with various diesel fuels.
Care: Store the box in a clean, dry environment to prevent contamination or corrosion. Keep the box closed when not in use to protect the washers from dust and debris. Inspect washers for any damage or defects before use. As these are consumable parts, they are not intended for reuse once a seal has been made.
