3539-14/p-866 Stop Valve, 3/4 In Connection, Cts, 250 Psi Pressure, Plastic Body

The Watts 3539-14 is a quick-connect stop valve designed for PEX, copper, and CPVC pipe systems. This push-to-connect fitting eliminates the need for installation tools, solder, or thread sealant, making it ideal for new plumbing installations, repairs, and replacements. Simply cut your pipe and push the tubing into the fitting until it seats at the stop. Disconnection is equally simple: pull back on the ring and release the pipe. The valve works with hot and cold water applications and is approved for behind-wall installations and direct in-ground burial, making it versatile for both visible and hidden plumbing runs.

Built from off-white polysulfone, a high-performance thermal plastic material, this one-piece valve resists cracking under vibration and pressure while remaining corrosion-resistant. Its unique O-ring guide provides zero-leak connections, and the design rotates under pressure for flexibility during installation. With no parts to assemble or lose, this fitting offers consistent performance and reliable service for many years.
