Manufacturer profiles associated with Gas Injection Manifold.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The operating pressure range is 1.0–1.6 MPa, as listed in the directory. The manifold should be operated within the specified range. Always confirm the exact pressure rating for your specific model with the manufacturer.
The manifold is available with 4 to 12 ports, depending on the configuration. The number of ports can be customized per process requirements. Verify the port count and arrangement with the supplier for your application.
The body is available in Stainless Steel 316L or Aluminum Alloy, with 316L being corrosion-resistant for high-purity gases. The seal material is Viton, compatible with most process gases. Confirm material compatibility with your specific gases and conditions.
The manifold is helium leak tested to a leak rate of ≤1×10⁻⁹ Pa·m³/s, per ISO 15848-1. This ensures high integrity for vacuum applications. Always verify the leak test results for the actual unit supplied.
