This fitting has a standard 1/4" barb on one end and 1/4" threads (10/32) on the other end. It is used to connect Rigid Riser (5 Pack) to mainline tubing or 1/4" micro tubing.
To use, simply twist the threaded end of the connector into the Rigid Riser and insert the barbed end into a hole punched in the mainline tubing, or directly into 1/4" micro tubing.
Use the back of the Yellow Handle Punch to thread the connector to the Rigid Riser.
Use a Stabilizer Stake to support Rigid Risers when inserted into mainline tubing.
