Description

The Pentair 071442Z 18" O-ring kit is a channel-style tank seal used on supported Nautilus Plus and SMBW 2000 series filters. This is not just a basic round gasket. It is a red-line channel O-ring designed to match the original sealing setup on specific Pentair tank systems. When the old seal is brittle, stretched, or leaking, replacing it with the correct OEM-style part is the right fix.

Pro Tip

Before installing the new O-ring, clean the channel and inspect the clamp and tank sealing surfaces. A fresh seal will not solve leaks caused by debris, damage, or poor clamp alignment.

Installation Tips

Shut the system down fully and relieve all pressure before opening the tank. Confirm the filter model before ordering, seat the O-ring evenly in the channel, and avoid twisting or pinching it during reassembly.
