Stein Seal Industrial

When industrial seals fail in the field, the consequences can easily become high-cost and high-consequence.

What’s at stake: Unplanned equipment downtime, fluid system contamination, pressure loss across critical interfaces, potential safety incidents for workers…these are all within the realm of possibility. A lot of operations today literally can’t afford those risks if they become reality.

That’s precisely why every seal leaving our facility is not just manufactured to specification, but tested and validated under a multitude of high-performance conditions that replicate real-world service loads and edge cases. We perform full dynamic validation, including upset condition testing such as loss of gas supply, temperature excursions, and over- / under-pressure events.

The result is comprehensive data you can trust, which translates to superior seals that you can count on to perform flawlessly up to the expected service life.

Innovating the Future of Turbine Sealing Technology
For decades, brush and labyrinth seals were the go-to for gas turbines—but innovation doesn’t stand still.

In our latest blog, we dive into the development of two game-changing sealing technologies:

🔹 The Aspirating Seal – A zero-contact, dry-running solution designed for extreme high-speed, high-temperature environments.
🔹 The Carbon Hydrostatic Face Seal – Engineered for high-pressure and shutdown conditions, delivering low leakage, long service life, and no need for oil lubrication.

From aviation and energy to oil & gas, these advanced seals are reshaping reliability and performance across industries.

Low-pressure turbine seals—such as piston rings—don’t always get the credit they deserve. But in land-based turbines, these components contribute mightily to keeping the lights on in our homes and cities.
In our latest blog, we take a closer look at why these seals, often derived from aircraft engine designs, are so well-suited for power generation applications.
Discover:
Why jet engine turbine seals last so long on land
How the longevity of just one seal can impact the entire system
How piston rings can outlast multiple engine rebuilds
Don’t miss this one. Find it here.

Discover how low-pressure turbine seals derived from jet engines deliver long-term performance and efficiency for land-based turbines in power generation and industrial systems.
