Durlon® 7910

Durlon® 7910 is a quality commercial grade compressed sheet gasket material, for moderate service conditions. It was specifically developed to meet the requirement of NSF/ANSI 61 (Certification for water treatment products that are manufactured, distributed or sold in North America) for potable water application 23°C (73°F) to commercial hot 82°C (180°F).

BENEFIT: Durlon® 7910 has a strong dielectric rating, making it ideal for isolation kit applications where compressed fiber sheet gaskets can be utilized.

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 contains high strength mineral fibers bonded with nitrile (NBR) synthetic rubber.
