JST Seals possesses comprehensive in-house capabilities to perform PR2 tests under stringent conditions, ensuring the reliability and performance of our sealing products. Our facility is equipped with advanced testing apparatus, including material abrasion testers, high- and low-temperature PR2/PR2F test systems, ultra-low temperature equipment using liquid nitrogen (-320.8°F / -196°C), and a range of custom simulation tools designed to replicate real-world operating environments.

We perform tests in accordance with industry standards and can also develop tailored testing programs based on specific customer requirements. Our equipment supports:

⚫ Test Pressure: Liquid: 0–50,000 psi │ Gas: 0–25,000 psi

⚫ Temperature Range: -94°F to 482°F (-70°C to 250°C)

⚫ Test Media: Water, oil, gas

⚫ Size Range: 2–9 inches

The configured system allows real-time monitoring and feedback of actuator movements, simulating actual device operation for accurate performance evaluation.

JST Seals has successfully conducted numerous validation tests for critical applications, including:

Moreover, JST is equipped with cryogenic testing capabilities down to -321°F (-196°C) using liquid nitrogen. We have successfully performed ultra-low temperature tests on spring-energized seals (e.g., TFM material with gold-plated alloy springs) under extreme conditions, demonstrating reliable performance even at -196°C.

At JST, we ensure that every seal meets the highest standards of quality and durability—validated through precise, customer-oriented testing.
