Like Swagelok's VCR, Parker's VacuSeal, and Fujikin's UJR series fittings, our VCR tee fittings are widely used in semiconductor manufacturing, solar energy, nuclear power, LED, TFT-LCD, petrochemical, and biopharmaceutical industries due to their ultra-cleanliness, high precision, leak-free performance from vacuum to high pressure, and extended service life. They play a critical role in ultra-clean (specialty) gas delivery systems.
Customers can choose between BA grade and EP grade based on process requirements. We offer three material options to meet different cleanliness levels: 316L, 316L VAR (single vacuum arc remelt), and 316L VIM+VAR (double vacuum melted).

Key Features of VCR Fittings
Exceptional Cleanliness
Surface roughness options: Ra 10 µin (0.25 µm) or Ra 5 µin (0.13 µm)
Superior Sealing Performance
Metal gasket face seal ensures zero leakage from vacuum to high pressure.
Wide Temperature Resistance
Withstands temperatures up to 537°C (with SS316L gaskets).
Extended Service Life
Silver-plated internal threads prevent wear and galling.
Enhanced Safety
Integrated test ports on nuts allow easy post-installation leak checks.
Space-Saving Design
Requires minimal clearance for installation/removal.
Strict Manufacturing Process
Raw Material Inspection → Precision Machining
Mechanical Polishing → Multi-Stage Cleaning
Electropolishing (EP) → Passivation
Final Rinse & Drying (Performed in a Class 100 Cleanroom)
Cleanroom Packaging
Design & Assembly
5 Components: 2 tube ends, 1 male nut (external thread), 1 female nut (internal thread), and 1 metal gasket.
Sealing Mechanism: Tightening the nuts compresses the metal gasket, creating a permanent deformation for a leak-tight seal.
Installation Guide:
SS316L/Nickel Gaskets: Tighten the female nut 1/4 turn after hand-tightening.
Copper Gaskets: Tighten only 1/8 turn.
⚠️ Warning: Gaskets are single-use only and must not be reused.
