Durlon® 5000

Durlon® 5000 is a good quality commercial grade compressed non-asbestos sheet with good chemical resistance for moderate service conditions suitable for oil, water, mild alkalis, mild acids, hydrocarbons, and solvents.

Durlon® 5000 contains high strength mineral fibers bonded with nitrile (NBR) synthetic rubber. A release agent on both sides provides good anti-stick properties.

Durlon® 7900

Durlon® 7900 is an economy grade general service gasket sheet material made with NBR (Nitrile Butadiene Rubber) binder for mild service in piping and equipment with applications in steam, hydrocarbons and refrigerants. An economical alternative when service ranges and applications are not severe.

This series is made from aramid and a NBR general-purpose material. The economy compressed sheets are proven to significantly lower emission levels. Each material in this series is color-coded for easy identification; all full-sized economy compressed sheets are date coded and quality assurance traceable.

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® 7925
