Introduction
ASA HV Tees (Grooved & Flat Flanges) are high-vacuum pipeline components designed to provide reliable branching connections in medium and high vacuum systems. Available in both grooved flange (O-ring sealed) and flat flange configurations, these tees offer flexibility for different sealing methods and system requirements.
Widely applied in thin film deposition systems, vacuum furnaces, semiconductor processing lines, and research vacuum setups, ASA HV Tees combine structural integrity, vacuum tightness, and convenient assembly.
Detailed Description
ASA HV Tees are typically manufactured from high-quality 304L or 316L stainless steel. These materials provide excellent corrosion resistance, mechanical strength, and low outgassing performance, which are critical in high vacuum environments.
Two primary flange types are available:
Grooved Flange Type
Designed for elastomer O-ring sealing
Quick clamp-based assembly
Suitable for high vacuum applications requiring frequent maintenance
Cost-effective and easy to install
Flat Flange Type
Flat sealing surface for gasket-based sealing
Compatible with specific bolt-through flange systems
Provides stable mechanical alignment
Suitable for semi-permanent installations
All tees are precision-machined and TIG welded to ensure structural stability and leak-tight performance. The internal bore is smoothly finished to minimize turbulence, particle trapping, and virtual leaks.
Surface finishing and dimensional tolerances are carefully controlled to meet vacuum industry standards, ensuring consistent sealing performance.
