Product Description

Product Description

Bolted Blank Flange, NW-80 Vacuum Fittings, ISO-LF Large Flange Size, Stainless Steel.
We manufacture a comprehensive range of flanges and flanged components such as nipples, elbows, tees, and crosses in all standard vacuum flange systems.
The ISO flange (also called Large ISO) is used for HV chamber ports and is available in two distinct styles; ISO-K which uses clamp fasteners and ISO-F which uses nut and bolt fasteners. A variety of bolt/clamp options permit joints between mixed ISO-K and -F flanges.
The design principles of ISO and KF seals are identical. Each flange face is counter-bored or grooved to receive a metal centering ring with an elastomeric o-ring around its O.D. As with KF, the ISO centering ring both aligns the flanges and holds the o-ring in place.

ISO Flanges are limited (by the o-ring's properties) to applications with temperatures between ~0° C and 120–180° C, and pressure from atmosphere to ~10-8 torr or mbar.
