ASA HV 5-Way Crosses (grooved flanges): Five-Directional Vacuum Distribution with All-Grooved ASA Flanges
ASA HV 5-Way Crosses (grooved flanges) from TFM are engineered for advanced high-vacuum (HV) systems that demand reliable, multi-directional connectivity. Constructed from 304L stainless steel tubing for strength and corrosion resistance, each cross features five orthogonally arranged ports, all equipped with rotatable grooved ASA flanges—ready to accept elastomeric o-rings and mate with flat ASA flanges for secure vacuum sealing.
Designed around the sexed ASA sealing system, this component simplifies the process of distributing vacuum access points from a central junction while maintaining consistent sealing geometry. Whether used for diagnostics, gas injection, chamber extensions, or pumping lines, these crosses enable robust and leak-tight performance across a variety of vacuum system architectures.
Key Features of ASA HV 5-Way Crosses (grooved flanges):
304L Stainless Steel Construction
Provides excellent chemical compatibility, mechanical integrity, and vacuum cleanliness, suitable for harsh process environments and pressures down to 10⁻⁸ Torr.Five-Port Configuration
Delivers efficient spatial access in multiple directions, ideal for applications where standard 4-way crosses are insufficient.All Grooved ASA Flanges
Each port includes a rotatable grooved flange, designed to seat an o-ring and mate with a flat ASA flange. This uniform flange design streamlines integration into vacuum networks that rely on flat-to-groove sealing.Rotatable Flange Design
Ensures easy alignment and flexibility during installation, accommodating complex layout requirements.Vacuum-Grade Clean and Tested
Every ASA HV 5-Way Cross (grooved flanges) is helium leak tested and cleaned to meet high-vacuum service standards.Standard Sizes and Customization Available
TFM offers common ASA sizes such as 4″, 6″, 8″, 10″, and 12″, with the option for custom tube lengths, reducer configurations, and non-standard flange arrangements upon request.
Typical Applications:
Vacuum chamber manifolds with diagnostic or utility ports
Gas distribution nodes with five-point delivery
Multi-directional pumping, sensing, or venting junctions
Modular high-vacuum architectures in R&D platforms
Cleanroom-compatible vacuum system expansion
To complete your system build, TFM provides ASA flat flanges, FKM and Buna-N o-rings, bolt kits, blanking plates, and custom transition adapters, ensuring full integration and long-term performance.
In summary, ASA HV 5-Way Crosses (grooved flanges) offer a robust and scalable solution for distributing vacuum access across five ports with consistent, grooved-side sealing. Their stainless steel durability, rotatable flange design, and vacuum compatibility make them an ideal choice for sophisticated HV system configurations.
