For consistentresults, you need to have the Right septa, liner and ferrule and you need to know when to change them.* When there are several options listed, the top recommendation in each category will work for most to Selecting the Right Inlet PartsThese Parts Are Just a SamEverything you need to know forGC inlets as well as a full listing inlet Parts and supplies are in AgInlet Resource Guide(5988-3466 Includes valuable tips for keeping inlets in top to ChangeVariable, and depends on needle condition.)
