CANADAS LEADER IN ENERGY PRODUCTS EQUIPMENT  Two PSI Regulators Two PSI Regulators are used as an intermediate regulator installed on the outside of a building delivering propane to a manifold inside the building that is used to distribute the gas to second stage regulators supplying approximately 11 WC to the appliances. The benefit of a 2 PSI system is reduced piping costs, as the higher pressure allows smaller diameter piping to be used. Two PSI systems are popular with CSST (Corrugated Stainless Steel Tubing) installations. These regulators are typically painted white for easy identification.
