  • AQUALOCK SERIES FITTING: Ideal for vibrating and dynamic applications, the AquaLock Series works with copper, CPVC, PEX (LDPE, MDPE, HDPE), and CTS rated pipe. Unlike barb fittings, this fitting joins the tubing on the outside, increasing the flow capacity, and rotates under pressure for high flexibility during installation.
  • DURABLE DESIGN: The Watts AquaLock Plastic Series is designed and manufactured in polysulfone – a high-performance thermal plastic material – for many years of trouble-free service life. They feature a unique O-ring guide that provides a zero-leak connection, making them perfect for DIY pipe repair.
  • QUICK CONNECT: Easy to install and handle, Watts AquaLock connectors utilize a swivel nut with NPS straight threads and a cone seal, which allow the installer to thread onto NPT, NPS, BSP, and most other threads without tools, tube inserts, or thread sealant. Simply thread on and hand tighten.
  • MULTIPLE CONFIGURATIONS: Capable of being used for hot and cold water applications, including behind-the-wall applications, Watts AquaLock fittings are reusable and available in a wide range of configurations and sizes to suit your needs. This model is a reducing coupling with a size of 1/2" CTS (Copper Tube Size) x 3/8" OD.
