{"product_id":"air-compressor-unloader-valve-for-5-16-tubing-part-st065700av","title":"Industrial ST065700AV Air Compressor Unloader Valve","description":"\u003cdiv\u003e\u003cp\u003eST065700AV is a 5\/16\" tubing air compressor unloader valve built as a direct replacement for Campbell Hausfeld models that use this size of unloader tubing. The unloader valve is part of the compressor’s unloading sequence: when the pressure switch stops the pump, the valve vents compressed air from the pump head to atmosphere, easing the motor's restart by reducing the start-up load. This part is specifically associated with 5\/16\" tubing connections and carries the ST065700AV designation for ordering and compatibility. In replacement catalogs and retailer listings, you’ll find ST065700AV listed alongside other 5\/16\" tubing unloader valves for Campbell Hausfeld air compressors, including related part numbers like TF038300AJ, indicating its role as a serviceable replacement in the Campbell Hausfeld family. Typical applications include replacing a worn or leaking unloader in 5\/16\" tubing circuits on small to mid-sized Campbell Hausfeld compressors used in home workshops or garages. By keeping the unloading function intact, this valve helps maintain reliable start-ups and consistent cut-out pressure, contributing to overall compressor performance without altering other electrical or mechanical components.\u003c\/p\u003e\u003c\/div\u003e","brand":"Campbell","offers":[{"title":"New","offer_id":46288975626474,"sku":null,"price":37.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-070.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/air-compressor-unloader-valve-for-5-16-tubing-part-st065700av","provider":"GTG Hardware","version":"1.0","type":"link"}
