Nor-Cal Products manufactures an extensive line of flanged flexible couplings. The hydroformed bellows assemblies are typically used for alignment correction or vibration isolation. Flexible couplings normally feature thinner wall thickness with a greater number of convolutions per inch, resulting in more flexibility than standard flexible hoses.

Nor-Cal's ASA flanges are manufactured from specially treated 304 stainless steel. These flanges mate with standard 150 lb. ASA flanges or 150 ANSI flanges. They are available from stock for standard tube sizes from two to 12 inches. Larger sizes are available upon request. ASA flanges can be baked to 204°C and have a vacuum range of up to 10^-8 Torr.

Nor-Cal Products offers a complete line of viewports for vacuum chambers with NW, ISO and CF flanges. CF flanged viewports are available with fully annealed 7056 glass or fused quartz. Special materials and coatings, such as sapphire and anti-reflective (AR) coating, are available on request. Glass provides a large distortion free viewing area at low cost. Quartz provides superior ultraviolet radiation transmission and resistance to thermal shock. Glass CF flanged viewports can withstand repeated bakeout cycles to 400°C and vacuum pressures to 10^-11 Torr. Quartz CF flanged viewports should not be baked above 200°C. NW and ISO flanged viewports can withstand 200°C bakeouts and pressures to 10^-9 Torr. Viewport shutters are mounted behind a viewport to prevent build-up of deposition materials on viewports while in the closed position. They use a single plate shutter with a 90º opening rotation. Nor-Cal’s design completely shields the viewing glass when the shutter is in the closed position. An integrated PRM-133 rotary motion feedthrough provides smooth actuation and a positive locking screw. Please call for custom actuation options, such as motor drives or special flanges. Glass adapters are available in 7740 Pyrex and 7052 glass, and supplied with NW, CF or ISO flanges. These adapters are useful for mounting glass accessories to metal high vacuum systems, or to attach flange mounted components to glass systems.

Add-A-Doors provide a simple, effective method of providing an elastomer sealed access port to an existing chamber fitting or component. These products include a 7056 glass viewport hinged door and easily bolts to a like CF flange using standard hardware. The door itself is secured with a single knurled knob. Standard finish is electropolish.

Nor-Cal's Aluminum to Stainless Steel Transitions provide a reliable UHV seal for aluminum vacuum systems. An explosion bonded composite of aluminum, stainless steel and two other UHV materials make these transitions leak tight at UHV pressures. Transitions are welded to a stainless steel CF flange as a complete unit ready to weld to your aluminum chamber or beamline, or the transition can be purchased separately for welding to your own CF flange.

Nor-Cal manufactures a complete line of vacuum fittings with CF flanges. The tube portions are fabricated from 304 stainless steel. On request 316 stainless steel can be supplied. Nor-Cal makes its own elbows, and all tees and crosses are made with the pulled port technique. This allows smooth, crevice-free butt welds to provide the maximum in cleanliness for UHV applications. Bake out range is up to 500°C.

Nor-Cal's double-sided flanges are identical to standard CF flanges except the same gasket-sealing detail is machined into both faces of the flange. These flanges can be inserted between like-sized flanges as spacers, orifice plates, or when radially drilled, as custom penetrations into vacuum systems.

Flange-to-fitting adapters are commonly used on chamber ports to connect flanges to special fittings. Nor-Cal offers these CF flanges for Swagelok, male and female VCR, quick disconnect, male and female NPT, ball socket and Welch pump fittings as standards. Other combinations can be supplied quickly as specials.

CF flanges are available with UNC or UNF tapped and untapped holes. Metric tapped or helicoiled holes can be ordered as specials. Tapped flanges have through holes, so bolts may protrude slightly from the back of the flange when fastened to an untapped flange. Untapped CF flanges can be fastened to each other with stainless steel bolts and hex nuts or plate nuts. 12-point bolts are available for CF flanges from 2¾ to 10 inch ODs. Silver plated bolts are available upon request to eliminate the need for anti-seize compound in clean room environments.

Nor-Cal's zero length reducer flanges are a convenient and inexpensive way to reduce a large flange for smaller vacuum plumbing and/or component connection. To list all possible reducer combinations would require excessive space, therefore only the most commonly used reducers are listed. If your requirement is not listed, please inquire.

Nor-Cal Products manufactures an extensive line of high and ultra high flanged vacuum viewports. Zero length fused silica viewports are available in NW, ISO and CF flange versions and feature a one-piece welded construction.

Conical reducers provide a compact means of adapting to a smaller diameter tube with minimal loss in conductance. They are available from stock in 304 stainless steel and some sizes are stocked in 316L stainless steel for additional corrosion resistance. Conical adapter nipples are available with various flange combinations.

Flange-to-flange adapter fittings are used as a transition between two similar flange types. We offer adapter fittings with flange combinations for CF (Conflat), NW (ISO-KF), ISO and ASA (ANSI) components as standards. We frequently provide other flange combinations as specials. Nipples usually have a short length of straight tubing between the two flanges.

Aluminum seals locate on the centering ring groove (inner centering) or outside edge of the flange (outer centering) depending on the size. (Inner and outer centering versions are available for all NW flange sizes.) Aluminum knife-edges are compressed by the sealing surfaces of the mating flanges when the chain clamp or ISO claw clamp is tightened. The resultant seal has a helium leak rate of less than 1x10-11 standard cc/sec. and can be baked repeatedly to 150°C.

Nor-Cal Products stocks a complete line of chain clamps and aluminum metal seals for converting elastomer seal NW (KF) and ISO flanges to UHV metal seals. They provide a number of benefits over elastomer seals: reduced outgassing, no permeation, no hydrocarbons, resistance to radiation and short half-life. Aluminum seals are used in high-energy physics, other UHV applications and, in some circumstances, cryogenic applications.
