💎 HIGH QUALITY: High quality red copper is used, not impure or alloy form copper, with red copper content of 99.8% or more. Red copper has good ductility and proper softness for better sealing.
💎 PROCESS: 1. Annealing heat treatment process. Increase the ductility of copper, reduce its hardness, appropriate softness, so that the copper gasket sealing stronger. 2. pickling and purification treatment. Form a passivation film on the surface of copper. After pickling and passivation treatment, the corrosion resistance of this copper gasket can be increased more than 10 times than other copper gaskets.
💎 COMPATIBILITY: Suitable for M18*1.5 oil drain plug, universal for Volvo.
💎 SIZE: Oil drain plug compression washer size: inner diameter is 18mm/0.71 inch; outer diameter is 22mm/0.87 inch; thickness is 1.5mm/0.06 inch, it is recommended to check your own plug gasket size is suitable
💎 VALUE PACKAGE: 20 red copper gaskets provide a tighter and more secure fit with longer lasting sealing ability than plastic or rubber seals, saving you money and time over your OEM parts selection.
