Models

AP STYLE 6300E

AP Services, a product and service brand of Curtiss-Wright, has state-of-the-art gasket manufacturing technology using CNC driven water jet cutters. Style 6300E is a graphite sheet manufactured from 97% pure graphite flakes containing a stainless steel tanged insert. These flakes are treated and processed without resins, binders, or other additives that would limit corrosion resistance and high-temperature applications.

Style 6300E is permanently resilient, non-hardening, naturally lubricious, and has an infinite shelf life. Flexible graphite has the seal of approval by companies handling corrosive, volatile, or flammable media.

Style 6300E is an ideal sealing material for high-temperature applications. It is also resistant to attack by most molten metals, corrosive chemicals, and caustics. Style 6300E is not an easy material to fabricate and is recommended that our customers order gaskets in finished form.

Style 6300E is available in sheets and pre-cut gaskets.

AP STYLE 6300P

AP Services, a product and service brand of Curtiss-Wright, has state-of-the-art gasket manufacturing technology using CNC driven water jet cutters. Style 6300P is a graphite sheet manufactured from 100% pure graphite flakes with a .0005” thick polyester (mylar) sheet laminated between the flexible graphite layers. The result is a mechanically stronger sheet with better handling characteristics, processed without resins, binders, or other additives that would limit corrosion resistance and high-temperature applications. Style 6300P is permanently resilient, non-hardening, naturally lubricious, and has an infinite shelf life. Flexible graphite has the seal of approval by companies handling corrosive, volatile, or flammable media.

Style 6300P is an ideal sealing material for high-temperature applications. It is also resistant to attack by most molten metals, corrosive chemicals, and caustics. Style 6300P is still an easy material to fabricate even with the polyester laminate.

Style 6300P is available in sheets and pre-cut gaskets.
