Through (Clearance) Holes

Through (Clearance) Holes

Are through-holes that allow adequate clearance for bolts to go through both flanges and secured by nuts or plate nuts.

Tapped Holes

Tapped Holes

Are imperial or metric threaded holes machined through the flange. This allows a clearance-hole flange to be connected without the need for nuts or plate nuts. Be aware of a components bolt hole orientation when selecting tapped flanges.

Fixed blank & bored Conflat flanges (CF) are available in an extensive range of sizes.

Fixed blank and bored flanges are a one-piece design where the bolt-hole orientation is fixed with respect to that fitting. Fixed blank flanges can be used to blank off chamber ports not in use to create a leak-tight assembly. These flanges can also be machined for custom tube sizes or components. Fixed bored flanges are designed to accept standard tube sizes and can be welded onto components.

Rotatable blank and bored flanges are comprised of two parts, an inner weld ring and outer bolt ring. This enables the bolt ring to rotate about the inner weld ring and allows the bolt holes to align to mating flanges in any orientation. Rotatable bored flanges are designed to accept standard tube sizes and can be welded onto components.

Both Fixed and Rotatable flanges are available with your choice of clearance-holes or tapped holes.

Clearance-holes: Through-holes that allow adequate clearance for bolts to go through both flanges and secured by nuts or plate nuts.

Tapped holes: Imperial or metric threaded holes machined through the flange. This allows a clearance-hole flange to be connected without the need for nuts or plate nuts. When selecting tapped flanges, be cautious of a components bolt hole orientation.
