· Posts. 1,774. Country Flag: Most copper washers that I''ve used have typically requires less force to crush and therefore seal versus similar aluminum washers, however either should work fine for you. I''ve seen variations in copper washers in terms of maleability/softness and have always assumed that it was just a alloy or processing difference ...
2009-12-7 · Copper crush washers really shouldn''t be re-used. To seal effectively the copper must be soft, as it is in an annealed state. The very act of crushing it under a bolt work hardens the metal, and years of being bolted to, say, your turbo, can have a tendency to age harden it as well.
· Both work fine. One advantage to copper is that you can anneal them to resoften them after they get work hardened. I have always reused aluminum or copper drain plug washers as long as they weren''t beat up looking and never had a problem. One washer can easily work for a …
Copper Crush Washers Page 2 Indian Motorcycle Forum Copper alloys such as C10100 or C11000 that most crush washers are usually are madefrom is 99.9% copper and considered to be a more noble metal; so less galvaniccorrosion occurs between it and aluminum.

The washers are so cheap I usually get them for free from my local motorcycle shop. I just go in and ask if I can buy one and they give me a handful for free.
· Some crush washers are just a soft metal washer like aluminum or copper. It really doesn''t crush that much, but it will work harden over time. Supposedly you can anneal it and regain some of the crushability, but I''ve never tried it. My experience is that these types of washers can generally be used indefinitely without leakage.
· Replumbing the brakes on my Olds and think that originally there was a copper crush washer between the front brake hose fitting and the wheel cylinder. Can anybody confirm this? If that''s what it is, I''m having a hard time finding the right size (7/16" id ) copper washer. How about using a Stat O Seal instead of the copper washer?
2021-10-3 · However, I''ve seen copper crush washers that had an embossed ring in the center of the washer that would actually crush down when under pressure. Today I had to replace the washers for an oil feed line for a turbo but the manual calls for copper washers and not crush washers. Do the flat copper washers work in the same way?
· Go to the auto parts store and purchase the correct size copper washer. This can be reused. Eventually it will become work hardened and then you will need to anneal it with a torch to soften it up again. Do not reuse the crush washer. They can form a wedge and cause the case to become cracked or have a piece break off. Search for photos.
· Looking at the washer that was on there, from the factory, it appears to me that the flat side goes against the plug. The part of the washer that crumples up was towards the pan. But like said it would probably work both ways. You would think the owners manual would say, since there is a section on changing the oil by the owner.
2019-6-17 · They work harden over temp cycles and become brittle which is why stress cracks can be seen in old washers. This is especially true with alloy crush washers that have been over tightened. They also do not re-seal if used again as they are harden and not forming correctly when torqued against an uneven surface defect.
2012-10-16 · Crush washers are maybe the most misused kind of seal in automotive work. They''re commonly found any time a threaded fastener has to seal in a liquid; the most common example is the crush washer under the oil drain plug of most cars. Tighten the plug, the soft copper washer deforms to fill any gaps, making a liquid-tight seal.
· Metals "work harden". An example is if you bend metal, you can never unbend it. The bend creases the metal because the metal is harder at the bend than along the unbent portion of the sheet. The crush washers are supplied in the soft state. Once used, they harden a bit. That''s one of the reasons a used crush washer may not seal.
· 68NovaSS said: This is what he''s talking about. I''m using one from Strange Engineering (N-1910) that''s very similar. It takes the place of the 9" crush sleeve using multiple thickness shims between two billet end pieces. Add/remove shims to achieve the correct rotational torque. I torqued my pinion nut to 175# and began checking rotational torque.

If they show a ridge or are squashed out of shape (oval) or if they are pitted then replace them. I buy mine in little packets from the supermarket for 2-3 euro''s for 5 washers.
· A material is needed that is hard enough to take the torque and soft enough for a good seal. In that case, I wonder why an aluminum gasket wasn''t used. Copper and aluminum tend to react with one another. With the sump being made of aluminum, a copper gasket would …
· Copper 110 is pure copper and would make a good seal washer when annealed. Copper washers are most easily made from sheet by punching, since copper is difficult to machine. Used copper washers can easily be annealed and used again if they are not too thin. Just heat to dull red and cool as fast or slow as you like.
· If you want to retain a OEM set up, buy the OEM washer, it is both a sealing washer, and partly responsible for creating the tension needed between the plug and case to keep it from vibrating out.. If you want to use a washer just designed for sealing, drill the plug for safety wire, use a fiber, aluminum or copper washer lightly tighten the plug so create a seal, and safety wire in place.
First, crush washers come to a knife edge on both mating surfaces – it is likely for this reason that a muzzle device is already misaligned just sitting on the crush washer before it is even torqued down. More importantly, it relies on the principle that the washer will deform uniformly while it is being crushed.
· This is was I used to do with the 1/2 copper washers on my older bikes. As soon as they showed any scratches or crushed areas I replaced them. Three times seems pretty save for me but at a $ 1.00 each from the stealer or for 1/2 copper drain washers at Napa for $ 0.40 they really could be changed every time.

· I heated the copper rings until it got red and let it cool off. That didn''t work so I bought 10 new copper washers and it steal leaks ridiculously bad. I have the copper washers on both sides of the bolt but it is always the same result. The top crush washer leaks at a rate of a drip a second.
· How does this Crush Washer work? Newbie Question: I ordered some crush washers and I got these in the mail. I know how the military silver aluminum crush washer works because the thin aluminum rings literally get "crushed" when you tighten the flash hider down, but these washers don''t seem to get crushed when I tighten them down.
2015-3-20 · Simple crush washer5. I have to use a copper crush washer to seal against coolant. The bolt is an M12x1.5 simple DIN 908 zinc plated bolt. There is a small interference of 0.1mm between the copper washer and the bolt (worst case), where the bolt surface starts to radius. I need to somehow model or calculate the crush of the material and ensure ...
· Upon removal, the previous filters were installed with copper crush washers. Being in a bind, I fabbed a couple up from some solid copper washers I had on hand. Later, reading the TM''s, I noticed the part number breakdown for the filter kit listed a fiber washer.

2 · Copper is a bendable, flexible metallic element that''s normally reddish-brown in color. If you hit it repeatedly, it becomes harder. On the other hand, copper can be softened even more than it naturally is. You may want to soften copper so you can bend it without crushing it or distorting its shape.
