Dial 9257 Brass Sill Cock 3/4 Inch Fip X 3/4 Inch Mgh X 1/8 Inch Side Tap Evaporative Cooler Fitting

Product Description

The DIAL 9257 is a brass sill cock designed for use with evaporative coolers. It functions as an outdoor faucet fitting that controls water flow and provides a reliable water source for filling or supplying water to an evaporative cooling unit. HVAC technicians and service installers commonly use this type of fitting when connecting a swamp cooler to a home or commercial water supply line. The 9257 features a 3/4 inch FIP (female iron pipe) inlet, a 3/4 inch MGH (male garden hose) outlet, and a 1/8 inch side tap port. The side tap allows a secondary connection point, which is ideal for attaching an angle needle valve or a male compression coupling with a 1/8 inch FIP connection. This creates a seamless link between the cooler water line and the main supply. The brass construction provides durability and corrosion resistance, making it well suited for outdoor plumbing applications where exposure to the elements is a concern. Brass fittings are a standard choice in evaporative cooler installations because they hold up to repeated use and maintain a reliable seal over time. The sill cock mounts through an exterior wall or along a supply line, giving technicians a convenient shutoff and access point for the cooler water feed. Proper water supply control is critical for evaporative cooler performance. A sill cock like the 9257 allows the technician or homeowner to shut off water to the cooler quickly without affecting the rest of the building water supply. This fitting is compatible with standard residential and light commercial evaporative cooler installations and is a direct replacement part for systems requiring a 3/4 inch FIP by 3/4 inch MGH sill cock with a 1/8 inch side tap. Dial Manufacturing has been producing evaporative cooler parts and accessories for over 50 years, and the 9257 is engineered to meet the performance demands of professional installers.
