No, copper sealing washers are designed to deform during the first use to create a seal and should be replaced with a new one every time the component is removed.
DIN 7603A refers to a German industrial standard for flat copper sealing rings, ensuring the washers have specific dimensions and material properties for reliable use.
Yes, these are suitable for many fuel and oil line applications due to their high-temperature tolerance and chemical resistance.
This specific pack (MPN HCU1723) contains 50 individual copper washers.
While they fit bolts with a 17mm shank, you must also ensure the outer diameter of 23mm and thickness of 1.5mm align with your specific housing requirements.
Check if the mating surfaces are clean and free of scratches. Ensure the bolt was torqued to the correct specification.
Ensure the washer diameter matches your bolt size exactly; the inner diameter should be 17mm.
Light oxidation on copper is normal and does not affect sealing performance; however, if pitted, the washer should be discarded.
To ensure proper performance, always clean the mating surfaces of the bolt and the engine housing before installation to remove old gasket residue or debris. Slide the washer onto the bolt thread and tighten using a torque wrench set to the manufacturer's specification. Avoid over-tightening, as this can deform the copper beyond its functional limit. Store these washers in a dry, low-humidity environment to prevent natural oxidation of the copper surface before use.
