Made of polyethylene, it is the primary feeder line from the 1/2" poly tubing to the plants. It may also be used as the basis for a complete system for containers and patio plants. Maximum working pressure for the micro tubing is 60 PSI, and maximum flow rate is 35 GPH. Available in 50', 100', and 500' in black only. DIG 1/4" polyethylene micro tubing is .170 ID and .250 OD. For extending drippers and micro sprinklers from main line or as the primary line in a small system. Resistant to UV rays. May be used above or below ground.

When using 1/4" tubing, try to keep your line lengths to 30' or less. Anything over 30' and you'll start to suffer from PSI loss due to friction within the tubing. This does not mean you cannot use more than 30' of 1/4" tubing in your system, it simply means that the maximum point-to-point water path should not exceed 30' for any single length of 1/4" line.
