Notes and selection guidance

• Ultra‑pure construction: The welded stainless interior and helium leak test make this model suitable where contamination must be minimized.
• Fitting and mounting: The 1/4" VCR male threaded port is common in high‑vacuum plumbing; confirm mating hardware and torque specs with your vacuum fittings.
• Set‑point and electrical choices: Verify whether your application needs a factory preset or field‑adjustable unit and whether SPDT or SPST switching is required.
