Air Compressor Check Valves
Does your air compressor fill up the tank, but stall when you try to restart it, and then 'kick the breaker'? Does your on/off switch leak through the unloader tube on the side after it cuts off and then continue to cycle on and off? These are symptoms of a failing or broken check valve, and a check valve is one of the most common parts that fails on a compressor.
Never fear, however; Master Tool Repair has air compressor check valve replacements for various air compressor brands. Don’t put up with faltering air compressor performance. A faulty check valve will cost you time, and time is money in your business.
