Description
Union Carbide Linde UPD-3-25-580 Compressed Gas Pressure Regulator w/ Gauges
Single-stage gas pressure regulator designed for specialty gas and oxygen service applications. Reduces high-pressure cylinder gas to controlled low-pressure output for laboratory, industrial, and medical gas delivery systems.
Specifications & What's Included
- Model: UPD-3-25-580 (Linde / Union Carbide)
- Inlet pressure range: 0–4000 psi
- Outlet pressure range: 0–30 psi / 30 in-Hg vacuum
- Two gauges included: inlet (0–4000 psi, U.S. Gauge BU-2581-A0) and outlet (0–30 psi, D&G)
- Brass body with CGA male flare fittings (inlet and outlet)
- Oxygen service rated; use no oil
- Benchtop or cylinder-mount configuration
Applications
These regulators were standard equipment in medical gas systems, laboratory gas delivery stations, and industrial compressed gas installations. Compatible with standard CGA-indexed cylinder connections. Commonly used in hospital respiratory systems, welding/cutting operations, and specialty gas research environments where precise pressure control and dual-gauge monitoring were required.
This Union Carbide Linde UPD-3-25-580 compressed gas pressure regulator is in good used condition overall. Both gauges are present and intact; however, the outlet (low-pressure) gauge is missing its plastic protective cover. The regulator body shows surface oxidation and general wear consistent with prior use. The brass fittings and CGA connections are intact with no visible damage.
