This is a full set of high quality pushrod tube seals for any 13-1600 and beyond style engine. Each tube requires a seal at each end, and there are 8 tubes, so a set includes 16 seals, for your convenience.
After trying every tube seal on the market, these are now the only seals I use in our engine builds. Others have surfaces that are not smooth, are chalky, stiff, too thin, or don't last. These have a great feel to them, seal great, and are the best on the market.
