Ingersoll Rand 85582229 Tank Check Valve 5/8 Flare X 3/4 MPNT

Description

The Ingersoll-Rand 85582229 Tank Check Valve is used in reciprocating air compressor systems to prevent compressed air from flowing back from the receiver tank into the compressor pump. Commonly installed in Ingersoll-Rand Type 30, SS5, TS5, 2340, 2475, and other compatible reciprocating air compressors used in industrial workshops, manufacturing facilities, automotive service centers, and maintenance operations. Maintenance technicians and compressor service professionals use this check valve for compressor repairs, preventive maintenance, and replacement of worn or leaking tank check valves.

Applications

The Ingersoll-Rand 85582229 is an OEM brass in-tank check valve designed to maintain system pressure by allowing compressed air to enter the receiver tank while preventing reverse airflow when the compressor stops. It features a 5/8 in. female inverted flare inlet, a 3/4 in. male NPT tank connection, a 1/4 in. FNPT port for a safety valve, and a 1/8 in. inverted flare port for the unloader tube. The valve is widely used in industrial and commercial reciprocating air compressors where reliable pressure retention and proper unloader operation are essential.
