Features of CF Fittings and Fittings:
- 1. CF flanges are designed in accordance with ISO 3669 and can be changed upon request.
- 2. Flange sizes are from CF 16 to CF250.
- 3. CF flanges are available in both rotatable and non-rotatable models with through holes or tapped holes.
- 4. Standard materials are 304 and 316L stainless steel.
- 5. CF products are supplied with a machining finish. Other finishes are also available.
- 6. Easy assembly or disassembly
- 7. The system can afford up to 932℉ (500℃) for copper gaskets; 399℉ (204℃) for Viton gaskets. However, sustained heating above 302℉ (150℃) may result in deterioration of the O-ring.
- 8. CF flanges are 100 % tested before shipping.
