Overview
Middle gasket for the HydraMaster recovery tank cover, listed as Gasket, Middle — Recovery Tank Cover. Self-adhesive neoprene.
Quantity depends on tank size: two per 70 gallon cover, three per 100 gallon cover. Getting the count wrong is the most common reason a tank rebuild comes up short.
What it fits
Named in the current parts books for the HydraMaster Boxxer 318HP, TITAN 575HP and TMTG4000, and fitted to earlier machines using the same Universal Recovery Tank.
HydraMaster calls the tank a Universal Recovery Tank (URT) in its parts books; CCW and much of the trade still call it the Airmax tank. They are the same tank.
The full cover gasket set
HydraMaster specifies a different set for each tank size. The side gasket is the part that changes, and the middle gasket quantity changes with it.

Frequently asked questions
How many do I need?
Two for a 70 gallon cover, three for a 100 gallon cover.
Does it fit both tank sizes?
Yes. Unlike the side gasket, the middle gasket part number is common to both — only the quantity changes.
Is it self-adhesive?
Yes. Clean the sealing face back to bare metal first.
My tank leaks vacuum after a service. Which gasket is it?
Most often a compressed gasket that was refitted rather than replaced. These are low-cost items; replace them whenever the cover comes off.
Rebuilding a tank rather than replacing one gasket? Send us your machine model and serial number and we will confirm the full set.
