Trusted across the industries
that demand the most
We understand the sealing challenges unique to your industry, and we know how to solve them.
Sealing expertise where it matters
Each industry has its own operating environments, regulatory requirements, and performance demands.
We match you with the right sealing solution.
Aerospace & Space
Seals for flight-critical hydraulic systems, fuel systems, actuation, and environmental control. Materials qualified to AS9100 and mil-spec requirements for extreme altitude, temperature, and pressure.
Medical Devices
Biocompatible seals for surgical instruments, drug delivery systems, diagnostic equipment, and implantable devices. USP Class VI and ISO 10993 compliant materials available.
Analytical & Clinical Lab Instruments
Precision seals for chromatography systems, spectrometers, sample handling, and fluid path components where chemical compatibility and ultra-clean performance are critical.
Semiconductor Processing Equipment
High-purity seals for etch, deposition, CMP, and wet clean tools. FFKM and specialty compounds engineered for plasma resistance, ultra-high vacuum, and aggressive chemistries.
Autonomous Defense Equipment
Rugged seals for unmanned systems, robotics, optics, and mission-critical enclosures. Designed for harsh field conditions including vibration, temperature extremes, and chemical exposure.
Energy (Oil, Gas, Wind)
Seals for downhole tools, valves, compressors, and processing equipment. High-temperature, high-pressure, and chemically resistant compounds for demanding energy environments.
Battery Technology
Seals for battery cell assemblies, electrolyte containment, thermal management systems, and manufacturing equipment. Chemical resistance to battery chemistries and tight dimensional tolerances.
Industrial Automation
Seals for robotic actuators, pneumatic cylinders, hydraulic presses, and automated assembly systems. Engineered for high-cycle durability and precision motion control.
Fluid & Gas Handling
Seals for pumps, valves, regulators, compressors, and piping systems. Chemical-resistant compounds for corrosive media, high-pressure, and cryogenic environments.
