ASA HV 5-Way Crosses (grooved & flat flanges): Multi-Port ASA Vacuum Connectivity with Mixed Flange Interfaces
ASA HV 5-Way Crosses (grooved & flat flanges) from TFM are designed to offer high-vacuum engineers a versatile, space-efficient solution for distributing vacuum lines or instrumentation across five axes. Fabricated from 304L stainless steel tubing, each cross is precision-welded and fitted with a combination of rotatable grooved and flat ASA flanges, enabling reliable sealing using elastomeric o-rings and standard ASA bolt hardware.
The sexed ASA flange system requires one flange to be grooved to hold the o-ring and the mating flange to be flat to compress it. With five ports positioned orthogonally, this cross offers a convenient and modular expansion point for vacuum chambers, pumping lines, diagnostics, or gas inlets.
Key Features of ASA HV 5-Way Crosses (grooved & flat flanges):
304L Stainless Steel Construction
Offers excellent corrosion resistance, vacuum compatibility, and mechanical durability, making it suitable for long-term high-vacuum use in industrial and research settings.Five Orthogonal Port Configuration
Allows connection of pumps, gauges, valves, or chamber extensions at multiple points—ideal for dense vacuum system layouts.Grooved & Flat ASA Flange Design
Each port includes a rotatable ASA flange, with a tailored mix of grooved and flat types to match system needs. When paired correctly, they provide leak-tight sealing down to 10⁻⁸ Torr.Rotatable Flanges on All Ports
Simplify alignment and installation, especially in systems where access is limited or exact orientation is critical.HV Clean & Leak-Tested
All ASA HV 5-Way Crosses (grooved & flat flanges) are cleaned to vacuum-grade standards and helium leak tested to ensure system integrity.Standard and Custom Options
Available in common ASA sizes like 4″, 6″, 8″, 10″, and 12″, with custom lengths, reducer flanges, or flange configuration adjustments available on request.
Typical Applications:
Five-direction vacuum chamber expansion nodes
Pumping and measurement junctions
Multi-port feedthrough or viewport integration
Gas injection and evacuation manifold designs
Compact distribution hubs in R&D or pilot-scale setups
TFM also supplies all necessary accessories for seamless system integration, including ASA bolt sets, FKM or Buna o-rings, blank flanges, and flange adapters, ensuring full compatibility across your vacuum network.
In summary, ASA HV 5-Way Crosses (grooved & flat flanges) deliver unmatched versatility for configuring high-vacuum systems with complex porting requirements. With a combination of sealing interfaces, rotatable mounting, and durable stainless steel construction, they’re ideal for modular vacuum layouts requiring high performance and reliability.
