Product Details

The AquaLock 3539-10 is a CTS (Copper Tube Size) in-line shut-off valve designed for quick, tool-free installation in residential and light commercial plumbing systems. Featuring AquaLock's push-to-connect technology, this valve allows installers to create a secure, leak-free connection simply by inserting compatible tubing into the fitting body — no soldering, clamps, or crimping required.

This in-line valve is ideal for applications where flow control is needed along a run of tubing, providing a convenient way to isolate sections of a plumbing system for maintenance or repairs. The valve's compact inline design makes it well-suited for tight spaces where traditional ball valves or compression fittings may be difficult to access.

  • Push-to-connect design — no tools, solder, or clamps required for installation
  • CTS (Copper Tube Size) compatible — works with copper, CPVC, and PEX tubing
  • In-line configuration for straightforward flow shut-off along tubing runs
  • Durable construction suitable for potable water applications
  • Compact form factor ideal for installations in confined spaces
