PerkinElmer 00090038 Gas Flow Restrictor Air Assembly

The PerkinElmer 00090038 Gas Flow Restrictor Air Assembly precisely regulates gas flow in laboratory GC systems, providing a controlled air or hydrogen supply to analytical instruments and helping ensure safe, stable operation. Designed for PerkinElmer gas chromatographs (GC) and flame ionization detector (FID) systems, this brass assembly uses compression fittings and includes the restrictor fitting, air restrictor, brass tubing nut, front ferrule, back ferrule, and PTFE thread sealing tape for complete installation as a gas supply line assembly. It is compatible with hydrogen carrier gas or instrument air and supports safe flow control in environmental, pharmaceutical, petrochemical, food testing, and research laboratories, helping minimize gas flow in the event of a line failure while maintaining proper operating conditions. Part number 00090038; common replacements include PerkinElmer N6500123, 00091297, and 00091417.
