ASA HV O-Rings & Hardware for Reliable Vacuum Sealing

ThinFilmMaterials offers a complete selection of ASA HV O-Rings & Hardware to support secure and efficient sealing in high vacuum (HV) flange systems. These components are designed to fit ASA-standard flanges, ensuring proper compression, alignment, and vacuum integrity for roughing lines, pump manifolds, and large chamber connections.

Our ASA HV sealing kits typically include high-quality elastomer O-rings (Viton®, Buna-N, or silicone), stainless steel bolts, washers, and nuts—precision-matched for each flange size and application. These accessories are essential for building or maintaining vacuum systems that use ASA flange terminations.

Key Features:

Compatibility: Designed for ASA-type high vacuum flanges (ANSI/ASME B16.5 pattern)
O-Ring Materials: Viton®, Buna-N, Silicone, others available by request
Hardware: 304/316 stainless steel hex bolts, flat washers, nuts
Sizes: Compatible with flange sizes from 1.5″ to 24″
Vacuum use: Suitable for base pressures down to 10⁻⁷ Torr (elastomer dependent)

Applications:

ASA HV O-Rings & Hardware are widely used in:

Pumping systems and foreline assemblies
High-vacuum process chambers
Gas inlet and exhaust lines in thin film equipment
Furnace systems and large vacuum enclosures
Research and industrial vacuum platforms

ThinFilmMaterials ensures consistent quality and compatibility with all our ASA HV flange components, offering complete hardware kits and replacement parts for routine maintenance or system upgrades. Custom O-ring materials and surface-treated hardware are available for specialty requirements.
