Each kit is assembled from premium compounds (NBR\/HNBR, PU, PTFE) and matched to factory tolerances to maintain correct sealing under high pressure and temperature cycles—preventing bypass, cavitation, and premature wear. Every set is bench-tested for extrusion resistance, compression set, and lip integrity to ensure stable cylinder performance in dust, heat, and vibration. With rugged materials and a factory-backed warranty, these kits reduce maintenance downtime, extend cylinder and rod life, and keep machines productive across construction, mining, and on-road applications\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFit to Models:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCaterpillar \u003c\/span\u003e\u003cspan\u003e120M, 120M 2, 12M, 12M 2, 140M, 140M 2, 14M, 160M, 160M 2, 16M\u003c\/span\u003e\u003c\/p\u003e","brand":"Caterpillar","offers":[{"title":"Default Title","offer_id":44976849486032,"sku":"307-6273","price":129.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8178\/5552\/files\/Caterpillar_307-6273_au.png?v=1778333804","url":"https:\/\/www.filtersandpartssolution.com.au\/products\/steering-cylinder-seal-kit-307-6273-fits-caterpillar-12m-140m-120m","provider":"Filters and Parts Solution","version":"1.0","type":"link"}
