The OLSON 6626 is a mini-sprinkler head designed for low-volume irrigation applications. It delivers a flow rate of 17 gallons per hour (GPH) through a 3/8-inch Male Iron Pipe Thread (MIPT) inlet connection and uses a 10/32 thread mounting configuration. The green color-coding indicates its flow rate classification, making quick field identification straightforward for irrigation technicians. This type of emitter is typically installed in micro-irrigation systems where controlled, targeted water distribution is required over planting beds, nursery stock, or landscape zones.
The OLSON 6626 is suited for residential and light commercial drip and micro-irrigation systems. It fits into systems where low-volume overhead or near-surface watering is needed, such as nursery benches, raised beds, greenhouse applications, and landscape borders. Irrigation contractors and landscape professionals install this sprinkler head as part of a broader micro-irrigation layout connected to standard poly mainline or header tubing.
Designed as an OEM-style replacement or standard component for residential and commercial micro-irrigation and drip system assemblies using 3/8-inch MIPT threaded connections.
Installation is typically performed by licensed irrigation contractors or landscape professionals. Shut off the irrigation supply line and relieve system pressure before threading the sprinkler head into place. Use appropriate thread tape or sealant on MIPT connections to prevent leaks. Follow local irrigation codes and water authority guidelines when installing or modifying micro-irrigation systems.
