The DIG 1/4″ Barbed Tee is used to connect three ends of 1/4″ micro tubing with .140 ID to .170 ID, to connect or extend and branch two lines of micro tubing from the drip tubing. By using a barb, the micro tubing is pushed over the barb for a very tight fit. Use for continuing lengths of micro tubing or to extend lines of micro tubing from the poly tubing.
