CUSTOM SEAL SOLUTIONS FOR DEMANDING APPLICATIONS
With decades of industry experience, we have developed deep expertise in custom seal solutions, polymer seal design, and application engineering for machined components. This means we don’t just supply seals; we provide effective problem-solving strategies.
Every customer challenge is met with a tailored seal design proposal and quotation, at no cost to you.
Our sealing experts guide you through the entire process, leveraging the latest advances in spring energized seals, engineered plastics, and metals.

Our spring energized seals, machined from PTFE and other high-performance fluoropolymers, represent premier custom seal solutions. Each seal is pre-loaded with a corrosion-resistant spring that ensures a consistent sealing force throughout its lifespan, adapting effectively as conditions change. We offer a wide range of jacket and spring
Our spring energized seals, machined from PTFE and other high-performance fluoropolymers, represent premier custom seal solutions. Each seal is pre-loaded with a corrosion-resistant spring that ensures a consistent sealing force throughout its lifespan, adapting effectively as conditions change. We offer a wide range of jacket and spring designs that can be configured across cantilever and helical spring types, making them suitable for radial, axial, and rotary applications. Additionally, these seals can be tailored for long life, low friction, or maximum sealing force, specifically tuned to meet your pressure, speed, and service life requirements. The innovative spring energizer compensates for wear, tolerances, misalignment, and eccentricity, thus maintaining reliable performance over time, an essential feature in high-quality machined components.
