    59686-33600 Front Master cylinder o-ring dimensions

    I’m looking to order the correct oring for my ‘78 GS750 master cylinder. The parts fiche doesn’t show the correct o-ring (cross section too thin) so I was wondering if somebody Had the dimensions for 59686-33600 handy.

    Thanks

    There are O-ring calculators online that can help. O-rings need a little stretch and crush when installed to function properly. If you can't get the help you need online post up some dimensions and someone here can help.

      If you are going to source your own You need Ethylene Propylene Rubber (EPR) O-rings are suitable for use with corrosive Skydrol hydraulic fluid, as well as steam, water, silicone oils, brake fluids and alcohols. This material is known to display good heat and compression resistance.
