  • 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability
  • 10,000 psi hard seat pressure rating (@ 200°F maximum)
  • Available in Zinc-nickel plated steel, electropolished stainless steel, and brass
  • Viton® o-ring seal and Teflon® back-up ring below the stem threads to protect from corrosion and galling; Teflon® or Grafoil® packing optional
