Understanding Extended Heel Canted Coil Spring Seals:

Extended heel canted coil spring seals, also known as helical spring seals or spring-energized seals, represent a sophisticated evolution in sealing technology. The design incorporates a canted coil spring with an extended heel, allowing for increased contact and improved sealing capabilities. These seals are particularly well-suited for applications where traditional seals may face challenges such as high pressures, extreme temperatures, and aggressive media.

Key Features of Extended Heel Canted Coil Spring Seals:

Extended Heel Design:

The extended heel design distinguishes these canted coil spring seals from their conventional counterparts. The extension of the heel provides additional surface area for contact, enhancing the seal’s ability to maintain tight and effective sealing.

Canted Coil Spring:

The heart of the seal is the canted coil spring, a helical spring with a non-parallel axis. This unique configuration imparts controlled and consistent force on the sealing element, ensuring reliable contact with the mating surfaces. Materials like stainless steel or other alloys are commonly used for the construction of these springs to provide durability and resistance to corrosion.

Sealing Element:

The sealing element, often made from high-performance materials like PTFE (polytetrafluoroethylene) or other polymers, plays a crucial role in achieving effective sealing. The combination of the canted coil spring and the sealing element creates a dynamic seal capable of adapting to various operating conditions.

Customization Options:

Manufacturers of extended heel canted coil spring seals often provide customization options to meet specific application requirements. This includes variations in materials, dimensions, and pressure ratings to ensure optimal performance in diverse industrial settings.
