Product Description

Product Description

NAl-LOK brand was established in Shanghai in 2000, we focus on the production, research and development, salesof instrumentation valves, fittings, hose & tubing. 

NAI-LOK stainless steel vacuum fittings are precision-engineered to deliver leak-proof performance in high-vacuum and critical gas/liquid systems. Designed for industries requiring ultra-clean, corrosion-resistant connections, our fittings ensure superior sealing integrity even under extreme pressure and temperature conditions.

Key Advantages:

 Hermetic Sealing - Precision-machined surfaces and specialized gaskets prevent leaks in vacuum environments (10^-9 mbar range).
 High-Purity Materials - 316L stainless steel with electropolished interiors minimizes contamination, ideal for semiconductor, pharmaceutical, and aerospace applications.
Wide Compatibility - Compatible with KF, CF, and ISO flanges, offering flexible integration into existing systems.
Durability - Resists oxidation, chemical corrosion, and thermal cycling for long-term reliability.

Our strict control and mananemen of the enlire production process enables us to provide products that meet our customers reauirements for productsafety, functionality and design at competitive prices, while ensuring the shortest lead times in the market.
