Durlon® 7900 & 7950

Economical Durlon Solutions

Durlon 7900 (off white) and 7950 (blue) are our economy grade aramid fiber and NBR general-purpose gasketing materials specifically engineered to deliver unsurpassed sealability, temperature resistance, and bolt torque retention when service ranges and applications are not severe.

Durlon® 8300

Premium Durlon Solutions

Durlon 8300 is our premium grade, multi-service high strength carbon and NBR gasket sheet, designed to handle the extremes of pressure and temperature. As with all of our premium products, the versatility of this sheet enables the end user to standardize on one sheet for a multitude of applications and avoid the confusion of having to choose from several different sheets.

Specifically designed for applications commonly found in the power generation and chemical processing industries, the Durlon 8300 maintains excellent sealability during thermal cycling even in steam, hot oil, aliphatic hydrocarbons, natural gas, gasoline, solvents, inert gases, mild alkalis and acids.

Durlon® 8400

Premium Durlon Solutions

Durlon 8400 (gold) is our outstanding next generation material that provides the widest range of chemical resistance of any compressed non-asbestos material available today. It's designed for high pH applications in the demanding services found in the pulp & paper, chemical processing and power generation industries where traditional compressed gasket materials have fallen short.

Durlon® 8500

Premium Durlon Solutions

Durlon 8500 (green), our general-purpose "workhorse" material contains our unique blend of high strength aramid and inorganic fibers providing excellent results in steam, hydrocarbons, and new generation refrigerants. Durlon 8500 passed a modified API 607 fire test at an independent laboratory and has proven to be reliable in situations where temperature and pressure cycling causes failures of lesser quality materials.

Durlon® 8600

Premium Durlon Solutions

Durlon 8600 (white), is an outstanding gasket material containing our unique blend of high strength aramid and inorganic fibers providing excellent sealability in steam, condensate, and dilute acids and where a "white" gasket material or an SBR binder is required.

Durlon® 8700

Premium Durlon Solutions

Durlon 8700 (blue), is our premium neoprene (CR) gasket sheet combined with our unique blend of high strength aramid and inorganic fibers providing excellent sealability in services such as ammonia containing refrigerant systems.

Durlon® RCA

Durlon® RCA™ sealing system combined with Durlon® PTFE styles can replace standard full face gaskets in FRP, PVC, and other non-metallic and metallic pipe flanges where a low stress gasket is required. The RCA™ configuration reduces the total gasket contact area resulting in a lower seating stress at a given torque level, while preventing flange rotation. The RCA™ configuration can be cut from standard sheets resulting in a cost savings versus other low stress gaskets.
