Great product holds pressure for 24 hours but the one thing you should watch out for is that the one pipe connection rotates so when I was using the smallest bit for my dirtbike and i went to take it out the connection spun and I couldn't take it out because the spark plug is in a pipe for 4strokes so in the end I did but now I just tape it so it doesn't spin so if your getting it for your 4stroke TAPE IT TOGETHER
