Suitable for petrol, ethanol, diesel, oil, water. (E10-E85 compatible). The best quality hose with internal reinforcer and fully compatible with modern fuels 6mm internal diameter, 13.4mm external diameter. Rubber with internal fabric reinforcement strands (unlike some cheaper imported hose). Note that the wall of this hose is over 7mm thick - beware other hose available elsewhere with a thin wall which has been known to degrade/burst fast with predictable unfortunate consequences. Can be fitted with rubber ends and clips or high quality Magna Clamps (rubber ends, clips and MagnaClamps not included, see my other listings for these) IF YOU ALREADY HAVE END CAPS/CLAMPS (OR YOU ARE BUYING ELSEWHERE) PLEASE NOTE THE EXTERNAL DIAMETER OF THIS HOSE IS 13.4MM SO YOU WILL NEED A CAP/CLAMP LARGER T
