High-Purity Single Stage, Two Stage and In Line Brass Barstock Regulators
The HP721 series regulators are a single stage cylinder regulator available in brass (HP 721) or chrome plated brass (HP 721C) barstock for pressure control of non corrosive gases when pressure rise is not critical.
The HP722 series regulators are a two stage cylinder regulator available in brass (HP 722) or chrome plated brass (HP 722C) barstock for constant delivery pressure from full cylinder to near empty cylinder conditions.
The HP723 series regulators are an in line cylinder regulator available in brass (HP 721) or chrome plated brass (HP 721C) barstock.
