The Haltec A-145 Large Bore Valve Core is a short version core designed for heavy duty tire inflation systems used on trucks, buses, OTR equipment, and industrial machinery. Made from corrosion resistant brass, it fits 0.305-32 threaded large bore valve stems and supports a maximum pressure of 200 psi. Its high flow design allows faster inflation and deflation compared to standard valve cores, making it ideal for large volume tire applications. Compatible with Haltec IN-80A inflator adapters, the A-145 provides reliable performance in demanding service environments.
