Edwards Fittings

NW and ISO flange fittings

Choose the optimum material to match your application and budget AIuminum is ideal for achieving dependable cost-effective performance down to 10 (-7) bar. Edwards (formerly BOC Edwards) also offers 3I6L/DIN 1.4404 stainless steel fittings for rugged corrosion resistance in semiconductor processing and excellent repeatability in high vacuum applications. In addition, careful quality control of elastomer specifications ensures critical sealing materials deliver the low outgassing performance your vacuum system performance depends on. Edwards (formerly BOC Edwards) attention to detail on all specifications delivers fit-and-forget dependability for your vacuum equipment.

UHV ConFlat (R) flange fittings

Sealing principle A copper seal is squeezed axially and radially between two CF flanges, where knife-edges force the copper to cold flow. This flow is severely limited by the vertical flange wall which generates high pressures and fills surface imperfections to give a leak tight joint At high bake- out temperatures, the flange geometry maintains high internal pressures despite softening of the gasket. A radial groove extends right up to the sealing ring and provides for leak testing of the vacuum connection.

Materials

Our range of CF flanges are manufactured from AISI 304 stainless steel, which offers optimum performance at an affordable cost. Stainless steel 304 is used for the majority of UHV applications where a takeout temperature of up to 450 degrees C is needed. AISI 316LN stainless steel is recommended for special applications where a harder material, higher bake- out temperature and much lower magnetic permeability are needed: these fittings are available on special order terms.

Dimensions

Edwards (formerly BOC Edwards) CF flanges are manufactured to international standards and are compatible with all leading manufacturers. Metric flanges common in Europe and Asia use metric tapped holes and bored holes in flanges suitable for metric tubing. Flanges specified in inches, more commonly used in the USA, use UNF tapped flange threads and bored holes compatible with inch sided tube. Edwards (formerly BOC Edwards) offers both options.
