Detail Information

High-purity Brass Regulators are constructed of high-purity brass barstock, and have stainless steel diaphragms and metal-to-metal seals. They are suitable for use with high-purity (>99.995% pure) non-corrosive gases. Applications include:

  • High-purity carrier gas
  • Most gas chromatography applications

Regulators terminate in a 1/4 in. NPT Swagelok™ fitting.

Gas Pressure Regulator Features:

Barstock Body Construction

Barstock bodies have a lower internal volume than forged bodies, allowing for more complete purging of atmospheric contaminants.

Stainless Steel Diaphragms

Unlike elastomeric diaphragms, stainless steel diaphragms don't absorb atmospheric contaminants or allow them to diffuse into the gas stream.

Metal-to-metal Seals

Metal-to-metal seals provide reliable protection from inboard leakage of atmospheric contaminants.
