Rain Bird 1804 pop-up
Co-moulded wiper seal is moulded into the cap and features an encased plastic “cage” to provide unmatched resistance to grit, pressure, and the environment. Additionally, the pressure-activated, multi-function seal design assures a positive seal without excess “flow-by” which enables more heads to be installed on the same valve.
Strong stainless steel spring provides reliable stem retraction.
Two-piece ratchet mechanism on all models allows easy nozzle pattern alignment and provides added durability.
