Lay the 1/2" Poly Tubing along the desired path through your garden or landscape. Note: If you plan to run tubing in opposite directions you can use the Tee Fitting (MLF-34). To attach this fitting simply slide back one of the locking collars to expose the raised plastic ring. Firmly push the 1/2" Poly Tubing onto the fitting until snug and over the ring. Hold the Tubing in place while you thread the locking collar in a counter clockwise motion until hand tight. Hint: Before unrolling the tubing, turn your faucet on to let water flow out the end. Apply the End Fitting (see step 8). Now the weight of the water will make unrolling the tubing much easier.
