WS-OR-53139 Oring for Jumbo Filter Housing

Oring for Jumbo Filters - 5.3mm x 139mm

Fits both 10" & 20" Jumbo's

Always remove and relubricate when changing cartridges.

As O'rings extrude when the sump is tightened, the lubrication helps to 'stick the 'longer' Oring into place.

Do not over tighten the sump, as this flattens the Oring, which in turn makes it even harder to seal.

Orings should be replaced when they are no longer an 'O', or when they are stretched too much to be able to be put back into the sump groove.
