ASA HV Tees

ASA HV Tees for High Vacuum System Connections

ThinFilmMaterials offers a full range of ASA HV Tees designed for high vacuum (HV) piping systems where a clean and reliable three-way connection is required. These tees are constructed with ASA-standard flanges and provide a convenient solution for distributing or combining vacuum lines in complex assemblies.

Our ASA HV Tees are manufactured from high-quality 304L stainless steel or aluminum, ensuring excellent corrosion resistance and mechanical durability. Each ASA HV Tee features precision-welded or machined branch connections with smooth internal surfaces suitable for HV service. Sizes range from 1.5″ up to 24″ OD, and custom dimensions are available upon request.

Key Features of ASA HV Tees:

• Flange standard: ASA (ANSI/ASME B16.5 bolt pattern)

• Materials: 304L stainless steel or aluminum

• Branch types: Equal or reducing tee designs available

• Surface finish: Vacuum-compatible smooth bore

• Leak-tested upon request for vacuum assurance

Applications of ASA HV Tees:

ASA HV Tees are widely used in:

• Roughing and foreline vacuum piping

• Vacuum furnace systems and pump manifolds

• Large chamber gas or exhaust distribution

• Thin film deposition and plasma systems

• High vacuum integration modules in research labs

All of our ASA HV Tees are engineered for long-term service in harsh vacuum environments, supporting pressures down to 10⁻⁷ Torr. Hardware kits, O-rings, and flange accessories can be supplied to ensure quick and secure installation.

For specialized setups, ThinFilmMaterials also provides custom-fabricated ASA HV Tees with welded ports, side branches, or adapter transitions based on your system design.
