1/2 Inch Push to Connect Fitting Plugs

1/2" Push-In Cap Plug Fitting for Pure Water Systems

Prevent leaks and keep your setup clean with this 1/2" Push-In Cap Plug Fitting, made to fit standard 1/2" OD tubing—commonly used in pure water window cleaning systems.

When your system is off, the waste line from the RO membrane can continue to drip, especially during transport. This simple push-fit cap easily seals off the 1/2" waste line to stop any leftover water or preservative solution from leaking out.

It’s also a must-have when winterizing your system. If you’ve added a liquid/powder preservative to protect your RO membrane from freezing, this cap prevents that solution from dripping out during storage or transit.

• Fits 1/2" OD tubing (standard size for most pure water systems)

• Stops drips and leaks from the RO waste line

• Essential for winterizing your system

• Quick push-in installation—no tools required

• Reusable, durable plastic construction

Whether you're heading to a job or storing your system for the season, this little cap saves you cleanup and keeps everything sealed tight.
