[QUOTE="oexing, post: 173692, member: 1493"] Cyborg, these v-rings are meant to go on rotating shafts for axial sealing with their soft lip. You could use them in primary chain cases when there is a need for chain adjustments by shifting the separate gearbox. In those cases you cannot have common shaft seals as they will no longer be concentric to the shaft once you tension the chain. I wonder how you think about using v-rings in float chambers. There are lots of viton float needles plus their separate seats to go with them at Aliexpress. Just how to install the lot is another topic. I don´t know about your idea of using o-rings, depends where they would go. Common NBR o-rings are quite allright with modern fuel, don´t dissolve BUT swell a bit and get softer. So in many places no problem from that and no real need for Viton types. But when you look into Ebay.cn in my link, you can select lots of sizes in FPM/Viton . Seems many forumites tend not to use Ebay for unknown reasons - scared about gangsters ?
