Designed for use with many Flojet pumps, this 1/4" JG port fitting is simple to use. Just raise port clip on pump, insert fitting and push down on clip to secure port fitting. The fitting accepts standard JG (John Guest) 1/4" tubing and is simple to use: Just push tubing into port fitting and the tubing is "locked in" until you press the ring on fitting while pulling tube out. Brand new-most pumps that use these require 2 of these. We are selling this item individually.
