Full Contact Springs Overview
Full Contact Spring is also known as: Raco Spring,Continuous Contact Spring
This heavy duty, high load Full Contact Spring provides continues spring contact along the entire sealing lip. Its use is recommended for extreme static sealing conditions such as those involving cryogenic fluids, ultra-high vacuum and positive sealing of light gases. Standard cross a section designs are available and produced in continues length coil; shipped to you ready to cut and rolled to your final center lines. This spring must be welded after it is placed in the seal jacket.

Full Contact Springs Dimensional Data
The RACO Spring is a high load, full contact spring used in specialist harsh service conditions.
The high load makes them well suited to service in cold and cryogenic applications and the continuous band contact means that spring force is evenly distributed around the circumference of the sealing lip.
Initially developed for efficient and consistent functionality in the extreme environments of the gas and oil industry, turbine engines, missiles and rockets, Raco Springs are now proven for use in a wide range of applications.”
