lotus54 Posted October 2, 2020 Report Share Posted October 2, 2020 I’m working on a 2014 280 (Explorer)- inner O-ring is bad so I need new ones. The ones I got are too large. I think they are 82 mm and 104mm (have to measure diameter). Does anyone know the correct size and if any GasGas O rings are correct? Otherwise I guess I’ll have to source some Vitron O rings at Granger or something (States). Quote Link to comment Share on other sites More sharing options...

peterb Posted October 4, 2020 Report Share Posted October 4, 2020 Hi Lotus, we never liked the original Ossa O rings, they were too large for the groove outside diameters. We have been using GG O rings for many years which provide a good fit, I can give you the P/Ns tomorrow, it's late evening time here. Bye, Peter B.
