Description
Pacific Scientific 2653 Stainless Steel High Pressure Regulator 3000 PSI 316L
The Pacific Scientific 2653 is a dual-gauge stainless steel high-pressure regulator designed for precise control of compressed gas supply and delivery pressure. It features an all-stainless-steel body with a needle valve for outlet flow control, an AN/JIC-style male flare inlet fitting, and two pressure gauges — one for inlet (supply) pressure and one for outlet (delivery) pressure. The 316L stainless steel construction makes it suitable for use with corrosive or high-purity gases.

Applications
High-pressure stainless steel regulators like the Pacific Scientific 2653 are standard equipment in industrial gas handling, laboratory gas supply systems, semiconductor fabrication, aerospace testing, and specialty gas applications. The 316L stainless steel body is particularly well suited for use with reactive, corrosive, or high-purity gases — including nitrogen, helium, argon, hydrogen, and process gases used in clean-room and research environments — where carbon steel or brass regulators are not appropriate. Dual-gauge regulators are used wherever both supply pressure monitoring and regulated outlet pressure control are needed simultaneously. The AN/JIC male flare inlet is common in high-pressure tubing systems used in aerospace and industrial process piping. These regulators remain in active use across laboratory, industrial, and specialty gas environments.
This Pacific Scientific 2653 stainless steel high-pressure regulator has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in service. The stainless steel body and fittings show light surface marks and minor scuffing consistent with normal use, and the gauges, knob, and needle valve appear intact and undamaged.
