5000

NBR

Suitable for a steam, oil, water, mild alkalis and acids, as well as hydrocarbons and solvents.

5300

NBR

Durlon® 5300 is a commercial grade compressed non-asbestos sheet gasket material for moderate service conditions. It is suitable for a continuous operating temperature of 450°F (232°C); or a maximum pressure of 1000 psi (69 bar) at ambient temperature. It is suitable for steam, oil, water, mild alkalis and acids, hydrocarbons and solvents.

DuraSwell-7760

Aramid – Inorganic

DuraSwell is engineered for demanding applications that require superior sealability, conformity to flange surfaces, and recovery. Designed to react by a controlled swell when in contact with oils and fuels which assists to increase gasket stress in applications that require increased gasket loading that may be previously limited due to insufficient bolting or flange design factors

7910

Fibers/NBR 

Specifically developed to meet NSF/ANSI 61 for potable water applications.

7900 7925 7950

Aramid/NBR

Suitable for mild service in piping and equipment and OEM applications in steam, hydrocarbons and refrigerants. An economical alternative when service ranges and applications are not severe.

8300

Carbon/NBR

Premium grade compressed sheet gasket material that is excellent in steam and hydrocarbon services in the refining, petrochemical and power generation industries. Other applications include oil, water, mild alkalis, mild acids, and solvents.

8400

Phenolic/NBR

Extremely wide pH application range, can be used in process piping and equipment in chemical, pulp and paper, and other general industrial applications. Excellent for use in steam, mild caustics and acids in Class 150 and 300 service.

8500

Aramid -Inorganic/NBR
