Aqualine I50A-532 - 1/2" Brass Adjustable Circle Sprinkler

Aqualine I50A-532 – 1/2" Brass Adjustable Impact Sprinkler Specifications

What is the difference between the I50A-532 and the I50-532?
The I50A-532 is the adjustable part-circle version — its arc can be set anywhere from 20° to 340°, making it ideal for edges, corners, and irregular coverage areas. The I50-532 is a fixed full-circle sprinkler. Both share the same 1/2" brass body and 5/32" nozzle, but if you need to restrict coverage to a specific zone, the I50A is the right choice.

What does the "-532" mean in the model number?
The "-532" refers to the included nozzle size: 5/32 of an inch. This nozzle produces a flow rate of 2.6 to 5.0 GPM at 25–50 PSI. An alternate version, the I50A-964, is available with a 9/64" nozzle for slightly different flow and radius characteristics.

What inlet connection does this sprinkler use?
The I50A-532 uses a 1/2" MPT (Male Pipe Thread) inlet. It is designed to thread onto a riser, stake assembly, or swing joint. Make sure your riser or fitting has a corresponding 1/2" FPT (female) connection.

What water pressure is required for proper operation?
This impact sprinkler operates between 25 and 50 PSI. Below 25 PSI, the impact arm may not drive properly and rotation can be inconsistent. If your supply pressure exceeds 50 PSI, consider adding a pressure regulator upstream to protect the head and maintain proper trajectory.

Can I use this sprinkler for pasture or agricultural irrigation?
Yes — this is one of the most popular use cases for the I50A. Its 30'–40' radius and brass construction make it well suited for hay fields, alfalfa fields, pasture irrigation, and small-farm row crops. It is typically mounted on a riser or tripod stand and connected to a mainline via garden hose or poly pipe with the appropriate fittings.

Why choose brass over plastic for an impact sprinkler?
Brass construction significantly outperforms zinc or plastic in longevity and resistance to UV degradation, mineral deposits, and physical wear. The I50A's brass body combined with its white bronze arm and stainless steel internal components makes it one of the most durable impact sprinklers available at this price point — especially for commercial or year-round outdoor use.

What if I need greater flow or a larger coverage radius?
If your application requires higher flow or a longer throw, consider stepping up to the Aqualine I75A-532 3/4" Adjustable Brass Impact Sprinkler, which handles larger zones with higher flow capacity.

Can this sprinkler be connected to an irrigation timer or controller?
Yes. While impact sprinklers are often used with hose-end timers for portable setups, they can also be integrated into automated irrigation zones using solenoid valves and a controller. DripWorks carries a full range of irrigation timers and controllers to automate your watering schedule.
