Oil-Resistant Asbestos Rubber Sheets KNY400 – Compressed Asbestos Sheet for Oil, Fuel & Solvent Sealing
KNY400 Oil-Resistant Asbestos Rubber Sheets are compressed asbestos jointing sheets made from good long asbestos fibre, oil-resistant synthetic rubber, and heat-resisting packing materials, compounded and compression moulded into sheet form. The KNY400 grade is specifically formulated for sealing kerosene, petroleum, fuel oil, petroleum-based lubricating oil, alkali, and solvent media. Manufactured by Kaxite, a professional China manufacturer and supplier of asbestos sheets.
Oil & Fuel Resistant Max +150°C Working Pressure 1.5 MPa GB/T539-2008
Direct answer: The KNY400 Oil-Resistant Asbestos Rubber Sheet is a compressed asbestos jointing sheet with a tensile strength of 15.0 MPa, density of 1.6–2.0 g/cm³, compressibility of 7–17%, and a maximum working temperature of 150°C at a working pressure of 1.5 MPa. It is mainly used as a sealing gasket material for equipment in kerosene, petrochemical, alkali, solvent, fuel oil, and petroleum-based lubricating oil service.
KNY400 belongs to the Kaxite oil-resistant asbestos sheet family, which includes KNY150, KNY250, KNY300, KNY510, and KNY600 grades. Each grade is formulated to different tensile strength and oil-sealing performance levels, so engineers can choose the right balance of strength, resilience, and cost for a specific flange or engine joint.
Because it is made from long asbestos fibre with oil-resistant synthetic rubber, the KNY400 provides reliable sealing in automotive, motorcycle, agricultural machinery, and engineering machinery engines, as well as in oil pipeline joints. Request a quote →
