The Aqualine I50-532 is a full-circle brass impact sprinkler built for reliable, long-range irrigation of large lawns, pastures, orchards, and agricultural fields. Featuring a durable brass body and white bronze arm, this sprinkler is designed to handle the rigors of continuous outdoor use — resisting corrosion, wear, and the UV exposure that breaks down plastic alternatives. It ships with a 5/32" nozzle installed and delivers a consistent water stream at a 25° trajectory, reaching a radius of 30 to 43 feet with a flow range of 2.80 to 7.70 GPM at operating pressures between 25 and 60 PSI.
Impact sprinklers like the I50-532 are the workhorses of large-area irrigation — the familiar clicking rotation driven by the force of water against the deflector arm gives them their name and their staying power. The full 360° rotation ensures complete, even coverage with no dry spots, making this an ideal choice for uniform turf coverage or crop irrigation where consistent moisture distribution matters. The spray reaches its highest point 5 feet above the nozzle, giving it excellent throw even in moderately breezy conditions.
The I50-532 connects via a 1/2" inlet, making it compatible with standard riser assemblies and riser-mount stakes. For slopes, uneven terrain, and above-grade applications, riser-mounted impact sprinklers like this one are a proven, cost-effective solution. DripWorks carries a full selection of compatible stakes and risers to get this sprinkler elevated to the right height for your site. If you need a partial-circle or adjustable-arc version of this sprinkler, see the full Aqualine impact sprinkler lineup.

What makes a brass impact sprinkler better than a plastic one?
Brass resists corrosion, UV degradation, and physical wear far better than plastic. For permanent or semi-permanent installations — pastures, orchards, large lawns, and agricultural fields — brass impact sprinklers like the Aqualine I50-532 offer a significantly longer service life. The white bronze arm adds additional corrosion resistance at the most mechanically active part of the sprinkler.
What is the correct inlet size for this sprinkler?
The Aqualine I50-532 uses a 1/2" inlet. Make sure your riser, swing joint, or supply line is sized for 1/2" connections. DripWorks carries a full range of compatible stakes and risers and funny pipe and swing joints to connect this sprinkler to your system.
Can I change the nozzle to adjust the radius or flow?
Yes. The I50-532 ships with a 5/32" nozzle installed, but Aqualine offers replacement nozzle sizes including 3/32", 7/64", 9/64", 1/8", 3/16", and 11/64". Smaller nozzles reduce flow and can reduce radius; larger nozzles increase flow and throw. Refer to the Aqualine spec sheet (linked in the Downloads section below) for the full performance table by nozzle size.
What water pressure does this sprinkler require?
The I50-532 operates between 25 and 60 PSI. Performance is best within this range. If your supply pressure exceeds 60 PSI, use a pressure regulator to protect the sprinkler and ensure uniform distribution. At pressures below 25 PSI, the impact arm may not rotate consistently.
Is this sprinkler suitable for slopes and uneven terrain?
Yes — riser-mounted impact sprinklers are one of the best choices for sloped, uneven, or above-grade applications. Because they sit above the ground surface on a riser or stake rather than popping up from in-ground housings, they are easy to install and reposition on challenging terrain. DripWorks carries a variety of stakes and risers suitable for use with this sprinkler.
Can this sprinkler be automated with a timer or controller?
Yes. Like any sprinkler on a standard pipe or hose connection, the I50-532 can be controlled by an upstream irrigation timer or controller paired with a compatible zone valve. This allows you to set automated watering schedules without manual intervention.
Does this sprinkler have a partial-circle (adjustable arc) version?
The I50-532 is a full-circle (360°) model. If you need a partial-circle or adjustable arc impact sprinkler to avoid watering structures, pathways, or non-irrigated areas, view the full Aqualine impact sprinkler lineup for adjustable models.
Is there a Prop 65 warning for this product?
Yes. As noted in the Aqualine specification sheet: this product can expose you to chemicals including lead, which are known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. For more information, visit P65Warnings.ca.gov.
