Some rubbers, both natural and synthetic, will swell from contact with hydrocarbons (Vaseline, engine oil, petrol, diesel, etc.) but others don't. You have to know what you're dealing with. A bad example is the OEM o-rings used for the diesel intercooler elbow. No idea what they were made of, but I'm sure MGR knew what they were doing putting them here. So balancing service life against cost they decided there was money to be made selling regular replacements at £7 a pair. But if a hydrocarbon resistant type (eg Viton) had been used, most diesels would still be running on the originals.
So, always best to check O-Ring Compatibility:
