<p>This premium agricultural grade black polyethylene tubing is made of the highest quality resins and is UV resistant. This tubing is the same as used by commercial growers. It can be used for all landscape and gardening applications. This low-density polyethylene tubing is used to carry water throughout a drip system. It can handle up to 60 PSI and is not rated for constant pressure. Polyethylene tubing is "springy" and requires time to relax and stay in place. Polyethylene tubing is sometimes abbreviated as "poly tubing".</p><p>Please note: These rolls of tubing will arrive tightly wound to help reduce shipping costs. Some dimpling and creasing may be visible on the inside of the roll as well as banding strap indentations. It is a normal occurrence for tightly wound rolls and does not affect the performance or durability of the tubing in any way.</p><p>Tip: To minimize tangling lay tubing in sun for 40 minutes then stand on edge and unroll.</p><ul><li>Inside Diameter: .600 Inches</li><li>Outside Diameter: .700 Inches</li><li>Wall Thickness: .050 Inches</li></ul>
