Moen 140777 1.5 Gpm Flow Resistor Aerator

Product Description

The Moen 140777 is a 1.5 GPM flow resistor aerator designed for use in residential and commercial plumbing applications. This aerator installs at the tip of a faucet spout and restricts water flow to a fixed rate of 1.5 gallons per minute. Plumbers, maintenance technicians, and facility managers rely on flow resistor aerators to meet water conservation codes and reduce overall water consumption without sacrificing usable water pressure at the fixture. The Moen 140777 functions by combining a flow resistor with an aerator screen. The flow resistor maintains a consistent output rate regardless of fluctuations in supply pressure. This pressure-compensating design ensures the fixture delivers exactly 1.5 GPM whether the building supply runs at 40 PSI or 80 PSI. The aerator screen mixes air into the water stream, producing a smooth, splash-free flow that feels full even at a reduced volume. This type of component is commonly specified during faucet repairs, low-flow upgrades, and WaterSense-compliant retrofits. Replacing a worn or missing aerator restores proper flow rate control and prevents the faucet from running above code-allowed limits. The 140777 is a genuine Moen replacement part, making it a direct fit for compatible Moen faucet models. Using an OEM part ensures correct thread sizing, gasket compatibility, and long-term durability. This aerator is well-suited for kitchens, bathrooms, and utility sinks in both new construction and retrofit projects. It supports water efficiency goals in commercial buildings, hotels, multifamily housing, and healthcare facilities where flow rate management is essential.

• Fixed 1.5 GPM flow rate delivers consistent water output regardless of supply pressure variation
• Integrated aerator screen blends air into the stream for a smooth, splash-free flow at the faucet tip
• Genuine Moen OEM replacement part ensures proper thread fit and compatibility with applicable Moen faucet models

Product Highlights

The Moen 140777 flow resistor aerator provides reliable, pressure-compensating flow control at 1.5 GPM, supporting water conservation compliance and consistent faucet performance in both residential and commercial settings.
