Product Description

ISO Bored Blank Flanges points
ISO Vacuum Bored Blank Flanges are used for welding onto tubes to produce ports and connectors when manufacturing fabrications.Sealing is accomplished with a centering with a nitrile or viton o'ring squashed between a pair of ISO Flanges and pulled together using a clamp.
The ISO bored flanges are supplied in a sealed platic bag and a protective plastic cap for protection of the sealing surface. Material is 304 stainless steel, 316L stainless is upon request.
