Specification Brand : Passeal BulletPoint1 : Proudly Made in the USA BulletPoint2 : Toolless & Easy Installation BulletPoint3 : Metal gaskets are impermeable to gases and withstand moderately high temperatures indefinitely. The normal gaskets for stainless steel CF flanges are punched from 1/4 hard, high purity, oxygen-free (OFHC) copper stock. BulletPoint4 : The gaskets are then chemically cleaned and processed to minimize scratches and burrs. ConFlat (CF) flanges are used for ultra-high vacuum applications. BulletPoint5 : These fittings use a copper gasket and knife-edge flanges to achieve the high vacuum seal and can operate down to 10-13 torr (10-11 Pa) and can be heated to 450 °C for bake-out.
