Oval Hose is a lightweight and economical tubing designed to be used for headlines and laterals on drip irrigation and micro-sprinkler systems. Use with insert fittings and clamps. Lays flat when not under pressure. Orchard Tubing is a lightweight polyethylene tubing that is punchable, and is often used for a lateral distribution and supply hose for on-line drippers, or as a headline for small drip tape systems. More rigid than oval hose.
