About this product

The Rain Bird 1804 spray body is a 4 in. pop-up (no side inlet) with a co-molded, pressure-activated wiper seal minimizing flow-by so more heads run per zone.

The stainless steel spring retracts reliably, ratchet adjustment aligns patterns without tools, and all internal components service from the top. UV-resistant plastics and corrosion-resistant parts support Rain Bird nozzles.
