Metal Face Seal Fittings (Parker UHP fittings)
Interchange with Swagelok's VCR, Parker's VacuSeal, and Fujikin's UJR series connectors, they are widely used in semiconductor manufacturing, solar energy, nuclear energy, LED, TFT-LCD, petrochemical industry, and biomedical manufacturing due to their ultra-clean, high-precision, vacuum-high-pressure, leak-free, and ultra-long life. In particular, it plays a crucial role in the transportation of ultra-clean gases (specialty gases). Depending on the process requirements, customers can choose between BA grade and EP grade. According to the Application for material cleanliness level, we provide 3 materials to choose from: 316L, 316L VAR (single V), 316L VIM + VAR (double V).
Features of the connectors:
1. Ultra-high cleanliness
The average roughness of the standard surface polish on the connector and joint body can reach Ra 10 μin (0.25 μm) and Ra 5 μin ( 0.13 μm) optional
2. Excellent sealing Metal-faced
sealing, leak-free service from vacuum to high pressure
3. Ultra-wide temperature
resistance Using metal gaskets, Maximum temperature resistance up to 537°C (SS316L gasket)
4. Extra-long service life x
The internal thread of the female thread nut is silver-plated to prevent wear and tear
5. Super safety
Each nut end is designed with test holes, which is extremely convenient for leak-proof testing after connection
6. Superb space
Disassembly and assembly can be completed with only a very small space
How to match
Strict production process requirements:
Raw material testing - joint processing - mechanical polishing - repeated cleaning - electrolytic polishing - passivation - rinsing + drying
The final cleaning and packaging are all completed in the clean room, and the clean packaging is delivered to the customer.
