{"product_id":"hub-cap-window-kit-2-3-4-zst3595999","title":"HUB CAP WINDOW KIT 2.3\/4 - ZST3595999","description":"The Stemco Window Kit 2.3\/4 is a 2-3\/4 inch axle hub cap window kit that allows inspection of hub internals without removing the hub cap. The kit consists of a transparent window, gasket, window ring gasket and vent plug, supplied as a matched set for service work on compatible Stemco hub caps. The window height is 1.15 inches, giving clear visibility into the hub so bearing condition, lubricant level and oil quantity can be checked during routine inspections. Sealing components are manufactured from rubber to help contain lubricant and resist leakage in heavy-duty road use. The kit is engineered with corrosion-resistant materials suited to commercial truck and trailer environments. It is referenced against multiple Stemco hub cap assemblies and cross-referenced part numbers, supporting use across a range of heavy vehicle wheel-end applications. This replacement kit is installed during hub cap service to restore clear viewing and maintain correct sealing performance around the hub window.","brand":"STEMCO","offers":[{"title":"Default Title","offer_id":49060828610811,"sku":"ZST3595999","price":25.89,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/6030\/4123\/files\/40673.jpg?v=1783663104","url":"https:\/\/www.tranzmile.com\/products\/hub-cap-window-kit-2-3-4-zst3595999","provider":"Tranzmile - Truck Trailer \u0026 Parts","version":"1.0","type":"link"}
