Rolair 347035000F Check Valve 90 Degrees For Rolair Compressor

The Rolair 347035000F is a genuine OEM 90-degree check valve designed to replace a worn or failed valve in Rolair air compressors. This 347035000F unit features 1/2" NPT threading and a 90-degree orientation, enabling flexible installation in tight or angled plumbing between the pump and tank. As a one-way valve, it prevents backflow from the reservoir, helping seal and maintain tank pressure once the compressor reaches its operating level and cycles off. The part is listed as an official Rolair repair component (347035000F) in Rolair’s parts catalogs, confirming it as the correct OEM replacement for systems that use a 1/2" NPT check valve configuration. Typical applications include replacement on Rolair compressors that require a 90-degree, 1/2" NPT check valve to restore proper airflow direction and pressure maintenance, supporting standard shop air setups with compatible fittings.
