These header hoses can be used with any of our irrigation kits or with other watering systems. A header hose (5/8" or 1/2") delivers water from the source to the watering system. At 30 psi, and using a 1/2" × 50' hose, the flow rate is approximately 420 gallons per hour; for a 5/8" × 50' hose, the approximate flow rate is 720 gallons per hour. Use with fittings (available separately) such as straight connectors, T-connectors and elbows to make branches or 90° bends in the line. Compression ends, sold separately, are used to seal the end of the header hose.
