Components are fabricated from type 304 stainless steel or brass with a surface finish of 32 micro-inches. Assemblies are useable to 10-8 Torr and can be baked to 200°C. The maximum temperature for sustained use is 150°C. Note that repeated bakeout to 200°C can cause deterioration of O-rings and require their periodic replacement.
The compression of a Viton® O-ring can accommodate variations in a tube up to .005 inch. It is essential that all inserted tubes have accurate fractional inch diameters.
Quick-Disconnects have a bore clear through the body and do not restrict a tube from entering as far as desired into a chamber. Care must be taken when loosening the knurled compression seal nut for adjustment while the unit is under vacuum.
These fittings are also supplied mounted on Del-Seal™ CF and Kwik-Flange™ ISO KF for use on flanged ports. Refer to Hybrid Adapters.
