ASA HV Nipples for High Vacuum Piping Systems
ThinFilmMaterials supplies a complete range of ASA HV Nipples designed for high vacuum (HV) systems where robust, leak-tight tubular connections are required. These straight and custom-length nipples are welded or machined with ASA flange terminations, allowing direct integration into large-diameter vacuum pipelines and chamber assemblies.
Our ASA HV Nipples are available in a variety of diameters and materials, including 304L stainless steel and aluminum, and are offered in standard or customer-specified lengths. All nipples are fabricated to ensure high vacuum integrity, surface cleanliness, and mechanical strength for demanding industrial and research applications.
Key Features:
Termination: ASA flange ends per ANSI/ASME B16.5 bolt pattern
Construction: Seamless or welded tubing with flange collars
Materials: 304L stainless steel, aluminum, and custom alloys
Sizes: 1.5″ to 24″ OD, custom lengths available
Surface finish: Vacuum-compatible internal & external finishes
Applications:
ASA HV Nipples are commonly used in:
High-vacuum roughing lines and pump manifolds
Vacuum furnace and thermal processing systems
Large vacuum chamber piping and gas delivery lines
Load-lock and isolation chamber connections
Industrial and R&D vacuum infrastructure
All ASA HV Nipples from ThinFilmMaterials are manufactured to tight dimensional tolerances and are vacuum leak-tested when required. Optional services include electropolishing, pre-cleaning for UHV, and custom welding or assembly per customer drawings.
