About Canted Coil Spring Seal
Canted Coil Spring are sealing devices used to prevent fluid or gas leaks and maintain the tightness of a system. A tilted coil spring is a specially shaped spring whose coil axis is tilted. Canted Coil Spring Seal uses the elastic force of the canted coil spring to form a tight seal at the connection part. Compared with traditional spring seals, it has better sealing performance and adaptability.

Structural Composition
1. Sealing Face: The sealing face is the main part of Coil Spring Seal. It contacts the connection part and provides sealing effect. Sealing panels are usually made of metal or polymer materials with good sealing performance and wear resistance.
2. Canted Coil Spring: Canted Coil Spring is the core component of Canted Coil Spring Seal. It uses a special tilted coil design with a tilted coil axis. The inclined coil spring forms a tight seal between the sealing panel and the connection part through its elastic force. It provides appropriate sealing pressure to ensure effective sealing effect.
3. Sealing Seat: The sealing seat is the support structure of the Coil Spring Seal and is used to maintain the position of the inclined coil spring and the sealing panel. The sealing seat is usually made of metal or polymer materials and has good corrosion resistance and mechanical strength.
4. Spring Seat: The spring seat is a component that supports the inclined coil spring and is usually located inside the seal seat. It provides a secure point for the canted coil spring and ensures that the spring can properly exert pressure on the sealing panel.
5. Preload Device: The preload device is used to adjust the preload force of the inclined coil spring, that is, the initial pressure exerted on the sealing panel. By adjusting the preload device, you can ensure that the inclined coil spring maintains appropriate pressure throughout the sealing life and achieve stable sealing performance.
Принцип уплотнения
1. Contact seal: During installation, the sealing panel of Canted Coil Spring Seal is in direct contact with the sealing surface of the connection part. This contact seal design ensures tight contact between the sealing panel and the connection part.
2. Elastic strength of inclined coil spring: inclined coil spring is a key component of Coil Spring Seal. It uses a tilted coil axis so that the canted coil spring is compressed when installed. Due to the elastic force of the inclined coil spring, it exerts a constant force or pressure on the sealing panel.
3. Sealing pressure: The elastic force of the inclined coil spring forms a tight seal between the sealing panel and the connection part. This elastic force provides appropriate sealing pressure to prevent fluid or gas from leaking from the connection.
4. Adaptability: Due to the special design of the inclined coil spring, it has certain adaptive ability. Even if there is slight deviation or vibration in the connection part, the inclined coil spring can automatically adjust according to the actual situation to maintain effective sealing performance.
Through the elastic force of the canted coil spring and the design of the contact seal, Canted Coil Spring Seal can provide reliable sealing effect. When appropriate preload force is applied and installed correctly, it can adapt to different working conditions and media and provide long-term stable sealing performance.
Product Dimensional Data
Canted coil springs have the unique property of maintaining a near-constant load throughout their entire operating range. When the seal is energized, this means that the force and friction remain constant as the spring expands to compensate for lip wear. This gives the seal predictable performance throughout its operating life.
The spring’s ability to lie completely flat and recover fully also makes it ideal for non-sealing applications such as latching and connections.
