Brawn Seal
The one piece high pressure seal
K.C. Seals Brawn® Seal is a compact, double-acting rod or piston seal with almost no dead spots. The profile maintains non-twisting in dynamic applications, as required for many applications in exploration and production. The Brawn® seal is commonly used as a T-Seal replacement, as well as an O-Ring and backup ring replacement because of its high-pressure rating.

| Material | Description | Temperature Range |
| HNBR | HNBR (Hydrogenated Nitrile Butadiene Rubber) stands out as a premium sealing material, offering enhanced resistance to chemicals, oils, and temperatures, making it particularly suitable for harsh environmental conditions encountered in the oil and gas industry. Notably, HNBR showcases superior strength and retention of properties after long-term exposure to heat, oil, and chemicals, surpassing the performance of standard NBR. | -30°C to 150°C -22°F to 302°F |
| NBR | NBR (Nitrile Butadiene Rubber) is a highly valued sealing material due to its excellent resistance to oils, fuels, and other chemicals, making it an ideal choice for applications in the automotive and aerospace industries. With a temperature operating range, NBR provides versatility under varied environmental conditions. Very cost effective option. | -40°C to 120°C -40°F to 248°F |
| FKM | FKM (Fluoroelastomer) is highly regarded in the sealing industry for its exceptional resistance to high temperatures, chemicals, and aging, making it indispensable in aerospace, automotive, and chemical processing sectors. This material thrives across a wide temperature range, enabling its use in extreme conditions where other materials would fail. FKM’s remarkable compatibility with a wide variety of chemicals, including oil, fuel, and solvents, along with its ability to withstand harsh environmental factors, ensures its preference for high-performance seals, O-rings, and gaskets. Its robustness and longevity under aggressive conditions underscore FKM’s value as a premier choice for demanding sealing applications. | -20°C to 200°C -4°F to 392°F |
| TFE/P | Aflas, a fluoroelastomer developed by AGC Chemicals, is renowned for its outstanding performance in extreme environments, making it indispensable in various industries such as oil and gas, automotive, chemical processing, and food and pharmaceuticals. Composed of tetrafluoroethylene and propylene (TFE/P), Aflas excels with its exceptional heat resistance, tolerating continuous service temperatures up to 232°C (450°F), and demonstrates remarkable chemical resistance to strong acids, bases, oils, amines, and steam. Its durability is further enhanced by its resistance to oxidative and thermal degradation, ensuring longevity and reliability in aggressive conditions. Additionally, Aflas offers excellent electrical insulation properties, making it suitable for applications requiring high electrical resistivity. | -25°C to 232°C (-13°F to 450°F) |
