Which Way Does a Crush Washer Face for an Oil Plug?
When it comes to oil plugs, there are two types of crush washers: metal and rubber. Each type has a different way that it should face for the oil plug to work correctly. For a metal crush washer, the beveled side should always face towards the oil plug.
This will create a tight seal, preventing any leaks. If the beveled side is facing away from the oil plug, then it is likely that you will have an oil leak. As for rubber crush washers, they can be installed either way since they conform to the shape of the oil plug.
However, it is generally recommended that the flat side faces towards the oil plug, allowing for a better seal.

Can You Use a Crush Washer on an Oil Drain Plug?
If you’re asking whether you can reuse a crush washer on an oil drain plug, the answer is generally no. Crush washers are designed for single use and then discarded. The reason for this is that they compress when installed, creating a seal.
If you try to reuse a crushed washer, it will likely not compress as much the second time around and won’t provide as good a seal. This could lead to oil leaks. There are instances where you may be able to reuse a crush washer, but it’s generally not recommended.
If you decide to reuse one, ensure it’s in good condition (not damaged or bent) and that you install it correctly.
What Direction Do Crush Washers Go?
Crush washers are most commonly used to seal fluid or gas connections in automotive applications, although they can also be used for other purposes. The crush washer is a thin metal disc with a beveled edge that is compressed during installation to form a seal. The primary purpose of the crush washer is to provide a tight seal without requiring over-tightening of the fasteners, which could damage the threads.
Crush washers are usually made from aluminum or copper and are available in various sizes to fit different-sized fittings. There is usually an arrow embossed on one side of the crush washer that indicates the direction in which it should be installed. In most cases, you will install the crush washer with the arrow pointing away from the fitting that it’s sealing.
This ensures that when you tighten the fastener, the crush washer is compressed evenly and forms a proper seal. There are exceptions to this rule, so it’s always best to consult your vehicle’s service manual or the manufacturer of the parts you’re using to ensure accuracy.
What Size of Crush Washer is on Oil Plug?
Assuming you are referring to the oil drain plug on a car, the most common size is 14mm. However, it is essential to consult your specific vehicle’s manual to confirm. Some vehicles may have a drain plug that is either larger or smaller in diameter.
Crush washers are designed for single use and then discarded. They are made of soft metal and compress when tightened to create a seal between the bolt or screw and the surface against which it’s being pulled. This helps prevent leaks.
When changing your oil, it’s essential to use a new crush washer each time to ensure a proper seal.
