Insert and Olive 10-pack

Price is for a 10 pack, so a little pricey but still 20% less per olive/insert than the 2 pack. Nice to have spares on hand if you have multiple sets of Dominions.

With the 1-piece olive/insert, just make sure that you get full insertion of the insert into the brake hose, which is a little more difficult than with 2-piece setups. Hayes provides a good tip about marking the hose with a paint pen before pressing the olive, and in general I've found that using a needle driver tool is especially helpful with these.
