"These were excellent as used for the sealing of oil pipes on classic motorcycles. The 8mm diameter corresponds exactly to 5/16" Imperial which is the general standard for rocker box lube connections. Almost impossible to find elsewhere."
"I have bought them to fix an leaking coolant plug on my motorcycle. I was a bit worry if the copper won't be soft enough to seal round the plug but did job perfectly. I know that buying a whole set just to do a wee job is a bit of an overkill but they will last forever and will save me money in a long run.
"This copper washer set represents great value for money when compared to the individual price other people are charging per washer. Not only that, they come in a good storage box. I only needed a few for my present need, but by paying a bit more I have a good stock that will save me wasting time in the future. The overall quality is good, but there are a couple that were not perfect, so I have harshly removed one star from the reliability score."
