Overview – Copper Gaskets for High-Temperature & High-Pressure Sealing
Copper Gaskets are precision-engineered sealing components designed to withstand elevated temperatures, corrosive media, thermal cycling, and extreme pressure fluctuations. These gaskets are widely used in engines, compressors, flanges, exhaust assemblies, turbo systems, refrigeration units, and vacuum chambers. Due to Copper’s exceptional thermal conductivity, ductility, creep resistance, and malleability, Copper Sealing Gaskets adapt perfectly to uneven mating surfaces and provide leak-proof joints. We manufacture all variants including Flat Copper Gaskets, Solid Copper Seals, Crush Copper Washers, Annealed Copper Sealing Gaskets, Deep-Drawn Copper Gaskets, and custom pressed-form Copper components for both static and dynamic joints.
Copper Gaskets
Copper Gaskets are solid-section rings or profiles made from high-conductivity Copper and Copper alloys to deliver stable sealing under thermal stress. These gaskets are annealed for softness, ensuring conformity between metal-to-metal surfaces. Our capabilities include flat, corrugated, spiral, and step-profile Copper Gaskets used in engines, pipe connections, instrumentation equipment, hydraulic systems, and vacuum lines where dimensional accuracy and heat tolerance are critical.
Copper Sealing Gaskets
Copper Sealing Gaskets are engineered for applications requiring gas-tight and fluid-tight joints. These are routinely used in exhaust manifolds, turbochargers, fuel systems, refrigeration compressors, and pressure vessels. The material’s plasticity ensures controlled deformation, resulting in full-face sealing even on imperfect flanges. Our Sealing Gaskets are manufactured in ASTM-B152, C11000, C12200 (DHP Copper), EN CW004A, CW024A, and JIS C1100 with process options including annealing, stamping, CNC trimming, and gasket profiling.
Copper Pressed Gaskets
Copper Pressed Gaskets are produced using hydraulic presses, progressive die sets, and deep-drawing tools that deliver complex geometry with consistent thickness control. These products are ideal where rigidity and profile depth matter—such as engine head assemblies, industrial burners, HVAC compressor plates, EGR valves, and sealing housings. Pressed Gaskets achieve exact deformation on installation, making them suitable for long-life sealing in high-pressure equipment.
Copper Seals
Copper Seals are compact metal sealing elements designed for precision leak-proof joints in hydraulic, pneumatic, and fuel injection systems. Depending on customer requirements, we manufacture them in annealed, half-hard, or full-hard temper with optional plating finishes. These Copper Seals replace fibre washers in high-temperature areas and provide superior resistance to vibration, friction, and chemical exposure.
Copper Sealing Washers
Copper Sealing Washers, often called crush washers, are widely used in automotive sump plugs, brake lines, oil lines, and hydraulic joints. Their controlled crush property ensures immediate sealing upon tightening. Our washers comply with DIN 7603, BS 4518, ASTM B152, and OEM specifications. They are available in Solid, Tapered, and Chamfered profiles, all manufactured with close dimensional tolerances and smooth burr-free edges.
Copper Pressed Parts
Copper Pressed Parts are formed using multi-stage progressive tools to achieve deep profiles, ribs, curves, and structural strength. Our facility handles thickness from 0.20 mm to 6 mm depending on design. These parts include domed discs, housings, covers, press-fit caps, exhaust rings, and electrical assembly plates used in switchgear, lighting, and pump industries.
Copper Engine Gaskets
These are precision-engineered sealing components designed to handle extreme temperatures, high combustion pressures, and continuous thermal cycling found in internal-combustion engines. Manufactured from high-conductivity Copper such as C11000, C12200, CW024A, or C1100, these gaskets provide excellent malleability and conformability, allowing them to seat perfectly against uneven cylinder head and engine block surfaces. Copper Engine Gaskets are often annealed to achieve controlled crush characteristics, resulting in highly reliable sealing for high-performance engines, turbocharged assemblies, diesel generators, compressors, and motorsport applications. Their superior heat dissipation minimizes hotspots, prevents blow-by, and ensures long-term durability even in aggressive environments involving oils, coolants, and combustion gases. These gaskets are preferred in demanding OEM and aftermarket engine builds where stability, repeatability, and leak-proof performance are essential.
Copper Pressed Components
Copper Pressed Components cover all specialty press-formed geometries used in Automotive, Railways, Marine, Electrical, and Industrial machinery. These components are manufactured with strict tolerances, superior surface finish, and optional surface treatment. We support prototype, small-batch, and large-volume manufacturing with tool design support.
