ECUP-SEALS AND V-PACKS

ECUP-SEALS AND V-PACKS

The ECup-Seal is a high-performance, spring-energized U-cup seal engineered for critical sealing applications where reliability under pressure and extreme conditions is non-negotiable. Designed with a resilient outer jacket and an internal spring, the ECup-Seal ensures consistent contact and sealing force across a range of pressures, temperatures, and media types. This dynamic sealing solution is tailored for use in rod, piston, face, and rotary motion systems, offering flexibility across multiple industry sectors.

How It Works:

The sealing performance of the ECup-Seal is driven by its internal energizing spring, which maintains constant pressure against the sealing surface, ensuring low-leakage or leak-free operation even at zero system pressure. As the system pressure increases, it acts on the external jacket, enhancing the contact force initially generated by the spring. This combination of mechanical preloading and hydraulic activation makes the ECup-Seal ideal for static and dynamic applications alike, ensuring a tight seal throughout operating cycles.

Applications Across Industries:

CAAST ECup-Seals are suitable for a wide range of demanding applications including:

• Valves (isolation, control, and cryogenic types)

• Actuators and pumps

• Oil production and service equipment

• Compressors and rotary equipment

• Pressure caps, vessels, and subsea systems

• Cryogenic valves and vessels

Whether in onshore, offshore, or subsea environments, these seals deliver outstanding performance even in extreme temperatures and pressures.

Material & Configuration Options:

Available in various material combinations and profiles, the ECup-Seal can be customized for specific chemical compatibility, pressure ratings, and temperature tolerances. Multiple configurations are offered for Rod Seals, Piston Seals, Face Seals, and Rotary Seals, enabling precise engineering for custom applications. Its spring-energized design also allows usage in both dynamic and static sealing environments where high-cycle durability and long service life are essential.

Certifications & Compliance:

The ECup-Seal meets several international performance and safety standards, making it suitable for use in mission-critical applications. Certifications and tests include:

• NORSOK M-710 (chemical resistance and aging)

• ISO 15848-1 (fugitive emissions)

• API 6A and API 17D (oil & gas equipment standards)

This ensures that the seal performs consistently under the strictest regulatory and operational requirements, providing peace of mind in critical operations.
