The Aqualine I75-532 is a 3/4" brass full-circle impact sprinkler engineered for reliable, long-range irrigation across large residential properties, agricultural fields, orchards, pastures, and commercial landscapes. Built entirely from durable brass with stainless steel internal components, this sprinkler is designed to withstand years of continuous outdoor use without corrosion or mechanical fatigue. It ships pre-installed with a 5/32" main nozzle (opposing port plugged) and delivers a powerful, low-angle stream at a 25° trajectory — keeping water close to the target even in moderate wind conditions.
With a coverage radius of 40 to 70 feet and an operating pressure range of 30 to 80 PSI, the I75 is ideally suited for applications where wide, uniform coverage is the priority. The classic impact drive mechanism is time-tested: as the deflector arm beats against the stream, it rotates the sprinkler head in a full 360° pattern, distributing water evenly across the entire coverage area. The opposing nozzle ports allow the unit to be converted to a dual-nozzle configuration for higher flow applications, and the stream's highest point reaches 8 feet above the nozzle, giving it excellent throw distance without wasting water to excessive elevation.
The I75-532 connects via a standard 3/4" threaded inlet, making it compatible with most residential and agricultural pipe systems. Mount it on a riser, a stake, or a swing joint — and pair it with a DripWorks irrigation timer or zone valve for automated scheduling.

What does "full circle" mean — can this sprinkler be set to water only part of a circle?
The I75-532 is a fixed full-circle (360°) impact sprinkler. It rotates continuously around its full 360° arc and is not adjustable to a part-circle pattern. If you need adjustable arc coverage for corners, edges, or irregular zones, look for an adjustable-arc impact sprinkler in the Impact Sprinklers category.
What is the coverage radius of the I75-532?
The recommended spacing (effective radius) is 40 to 70 feet, depending on operating pressure and nozzle selection. With the installed 5/32" nozzle at typical operating pressures (30–60 PSI), the wetted diameter ranges from 81 to 88 feet — meaning an effective radius of roughly 40 to 44 feet per head. Space heads no farther than the wetted diameter apart for proper head-to-head coverage.
What is the minimum pressure needed to operate this sprinkler?
The I75's rated operating range begins at 30 PSI. Below this pressure, the impact arm may not rotate consistently and throw distance will be reduced. If your supply pressure exceeds 80 PSI, we recommend installing a pressure regulator upstream to protect performance and avoid misting or fogging caused by over-pressurization.
What is the second nozzle port for?
The I75 features opposing nozzle ports. As shipped, the unit comes with a single 5/32" nozzle installed and the opposing port plugged. The second port can be opened and fitted with an additional nozzle (such as a smaller "back nozzle") to increase total flow and improve distribution uniformity near the head. See the full spec sheet for dual-nozzle performance data.
Why is brass better than plastic for an impact sprinkler?
Brass impact sprinklers offer significantly greater durability and longevity than their plastic counterparts. The brass body resists UV degradation, cracking from thermal cycling, and physical impact from mowers or livestock. The stainless steel internal components — arm, spring, fulcrum pin, and washer — resist corrosion even in hard water or high-mineral environments, making this sprinkler a long-term investment for agricultural and commercial use.
What type of riser or connection does this sprinkler require?
The I75-532 uses a standard 3/4" female threaded (NPT) inlet. It can be connected directly to 3/4" pipe, a threaded riser, a spike stake, or a swing joint. For above-ground agricultural use on a stake system, it's common to mount these on a 1/2" or 3/4" riser pipe at 12"–18" above grade to clear crop canopy or turf.
Can I automate this sprinkler with a timer or controller?
Yes. The I75-532 is a passive mechanical sprinkler — it operates whenever water flows through it. Connect it to a zone controlled by a solenoid valve and schedule it with any irrigation timer or controller from DripWorks for fully automated watering.
Is this product subject to California Prop 65 warnings?
Yes. This product contains brass components which may expose users to lead, a chemical 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.
