Speedaire TF022200AV 3Z493 Valve Overhaul Gasket Kit

Speedaire TF022200AV 3Z493 TK21N Valve Overhaul Gasket Kit is a targeted maintenance solution for TF-series Speedaire two‑stage compressors, specifically matching 10 HP TK21N units. The kit (part number TF022200AV, 3Z493) provides the critical valve-head components needed to overhaul the reed-valve and head-gasket assembly, including a reed plate gasket, top head gasket, bottom valve-plate-to-cylinder gasket, and the main steel reed valve plates for both sides of the reed assembly, plus an air filter. It is designed for Speedaire TF-series pumps and TK-series applications, including models built for 10 HP operation, and is compatible with older systems using a valve-head and reed-valve design (pumps built before the early 1990s). Replacing worn gaskets and reed components with this kit helps restore compression sealing, reduce leakage, and bring back efficient airflow after valve wear, without replacing the entire pump.
