This 14 mm thread plug uses a flat-seat design with a single copper center electrode measuring 1.67 inches and an overall length of 3.96 inches; the hex across flats is 13\/16 inch, and the thread height is 14 mm x 1.25 mm. The I-31-1 configuration features one electrode and copper construction to support reliable spark delivery in typical burner ignition assemblies. Common applications include igniting burners in industrial equipment such as grain-drying systems and other commercial furnaces that rely on spark ignition. As an Auburn-branded replacement, this I-31-1 model is intended for installation in compatible Auburn ignition systems that specify the I-31-1 designation, helping ensure proper fit within standard Auburn installation envelopes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Auburn","offers":[{"title":"New Surplus No Box","offer_id":51660349210926,"sku":null,"price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5369f72f-3c56-4094-9c0e-b5df471fbb10.jpg?v=1769536567","url":"https:\/\/plgautomation.com\/products\/industrial-i-31-1-spark-plug","provider":"PLG Automation ","version":"1.0","type":"link"}
