Filtration Warehouse Leak Prevention Valve

10 Pack with container

Specifications

  • Height 2/5" (10mm)
  • Diameter 7/10" (18mm)
Snug Fit Design

Activation pads should fit tightly inside the trigger chamber to ensure a positive, vertical expansion.

Quick and Easy-to-Install Replacement Pads

Keep spares at the ready just in case!

Be prepared for a leak before it starts, but in the event your leak prevention valve has been triggered, our replacement pads will get you up and running again in seconds. It is never good to run your system without an expansion pad as costly water damage could occur. Keep a few of these on hand just in case.

Fits Most Systems

Our compressed expandable pads with wider design are designed to fit snugly inside the activation chamber of 17mm-19mm models to ensure they expand vertically effectively triggering the shut off valve. Other pads that fit loosely may not expand correctly, extending the time water is leaking before the device is triggered.

I had to return these since they were a fraction of a centimeter too big. They were shipped quickly, and the items were mostly as described. The return was smooth, and I would recommend buying from this seller.

Because of the busy holidays, I didn't bother to count how many I received in the little plastic box. There were only 8 instead of 10.
