DURLON® 7910 is a good quality general service gasket for applications where an NSF/ANSI 61 certified gasket material is required. It is suitable for potable water, steam, oil, water, mild alkalis and acids, hydrocarbons and solvents; and for applications in the water treatment and reclamation, wastewater and plumbing industries.
DURLON® 7910 is a compressed fibre sheet gasket material that was specially developed to meet the requirement of NSF/ANSI 61 for potable water applications. It contains high strength mineral fibers bonded with nitrile (NBR) synthetic rubber.
Much effort has gone into improving the anti-stick release agents of all compressed Durlon® products. All Durlon® compressed gasket materials have passed the MIL-G-24696B Navy Adhesion Test (366°F/48hrs).
