Product Description
Customized Rubber Seals Steel Combination Bonded Seal
This type of "rubber + metal" sealing gasket usually refers to a metal-reinforced rubber seal (also known as an envelope gasket or bonded seal). It combines the strength and dimensional stability of metal with the elastic sealing properties of rubber, and is mainly used in applications requiring high pressure resistance, temperature tolerance, anti-creep performance, and reliable sealing. Typical application scenarios include:
1. Automotive Industry (The Most Typical Application Field)Customized Rubber Seals Steel Combination Bonded Seal
Engine Systems: Such as valve cover gaskets, oil pan gaskets, crankshaft front/rear oil seals, and camshaft cover gaskets. The metal reinforcement ensures the gasket does not deform under high temperatures (over 100°C in the engine bay) and vibration, while the rubber layer (commonly NBR or FKM) seals engine oil and coolant to prevent leaks.
Transmission / Drivetrain: Transmission end cover gaskets and differential seals-resisting gear oil corrosion and mechanical pressure.
Brake Systems: Master cylinder and wheel cylinder seals-requiring resistance to brake fluid (e.g., DOT3/4) corrosion, with metal reinforcement ensuring stable sealing geometry.
2. Customized Rubber Seals Steel Combination Bonded Seal for Machinery & Industrial Piping
Pumps & Valves: Pump and compressor housing gaskets-where the metal part withstands operating pressure (hydraulic/oil pressure), and the rubber layer fills micro-gaps on sealing surfaces to accommodate minor displacement.
Hydraulic / Pneumatic Systems: Hydraulic cylinder end seals and pneumatic component seals-resisting hydraulic oil (mineral or synthetic oils) and high-frequency pressure fluctuations; the metal skeleton prevents rubber extrusion under high pressure.
Industrial Pipe Flanges: Small-bore, high-pressure pipe flange seals (as an alternative to all-rubber or all-metal gaskets)-for example, stainless steel piping in chemical plants or hydraulic stations, where the metal core enhances pressure resistance (up to tens of MPa) and the rubber layer adapts to uneven flange faces.
3. Home Appliances & Electronic Equipment
Washing Machines / Dishwashers: Inner drum-to-housing seals and drain pump seals-resistant to water and detergent corrosion, with metal reinforcement preventing loosening after long-term door opening/closing or vibration.
Air Conditioning / Refrigeration Equipment: Compressor housing gaskets and condenser seals-resistant to refrigerants (e.g., R32, R410A) and extreme temperatures (-30°C to 120°C) to prevent refrigerant leakage.
4. Aerospace & Precision Instruments (Specialized Scenarios)
Aircraft engine auxiliary systems and hydraulic line seals-requiring lightweight construction, extreme temperature resistance (e.g., FKM for >200°C, silicone rubber for -60°C to 200°C), and performance under low-pressure high-altitude conditions; metal reinforcement (aluminum alloy, stainless steel) ensures structural strength.
Why These Applications? Core Advantages
Compared with all-rubber gaskets, the metal reinforcement solves issues such as poor pressure resistance, creep, and high-temperature deformation. Compared with all-metal gaskets, the rubber layer eliminates the need for extremely high surface finish on mating parts (tolerating roughness Ra ≤ 3.2 μm), making installation easier and sealing more reliable.
In short: Any scenario that requires sealing liquids or gases while facing pressure, temperature variations, vibration, or imperfect sealing surfaces is a candidate for using this type of gasket.
