This universal window kit is engineered for heavy-duty truck and trailer hub caps and is supplied as a complete service kit, including the transparent window, gasket, window ring gasket and vent plug. The clear window construction provides reliable visibility of lubricant level and condition, while the included gaskets help control seepage and oil spray and assist in preventing water and contaminant ingress into the hub assembly. The vent plug is included to help regulate internal axle pressure during operation. Built from durable, corrosion-resistant materials, the kit is suited to demanding commercial vehicle wheel-end environments and supports routine fleet maintenance and hub rebuild work. This part cross-references a wide range of OEM and aftermarket hub cap numbers, making it suitable for use across many standard drive and trailer axle hub cap applications where a 3-1\/2 inch Stemco-style window is required.","brand":"STEMCO","offers":[{"title":"Default Title","offer_id":49057069039867,"sku":"ZST3595995","price":24.57,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/6030\/4123\/files\/26127.jpg?v=1783513144","url":"https:\/\/www.tranzmile.com\/products\/kit-hub-cap-window-3-1-2-zst3595995","provider":"Tranzmile Truck \u0026 Trailer Parts","version":"1.0","type":"link"}
