    Copper Crush Seal Rings

    If you have been involved with BMW motorcycles for quite some time, you might remember these soft, fiber filled crush washers. We are very pleased to offer these!

    When the drain plug or fastener is tightened, these crush washers compress much more easily than solid seal rings and they form a perfect seal without excessive torque. These are especially great when the threads are a bit marginal and you want to avoid high torque and further damage, but they are also ideal in all seal ring applications and represent good old school technology that gave way to cost cuts over the years.

    We offer the following sizes:

    • 8X12X1,5ex: Fork Damper Rods up to 1980, final drive inspection plug 1981-on
    • 12X18X2 ex: Swing Arm oil fill and drain, oil pressure switch
    • 14X20X2 ex: Gearbox & final drive drain
    • 18X24X2 ex: Oil drain plug, gearbox filler plug, final drive filler/vent

    Excellent Washer
    I picked up a few of these with my last order and they work excellent. I have had zero leaks and the offer the peace of mind I am not over tighten the oil or tranny drain bolt. A few cents more than the regular copper or aluminum washers but worth it.
