O Rings
Our precision-engineered O-rings are designed for leakproof sealing across critical systems. Manufactured to strict tolerances, they offer dependable performance across industries where failure isn’t an option.
Available in NBR, Viton, EPDM, and Silicone, these O-rings can be tailored for aerospace systems, food-grade equipment, hydraulics, and medical devices. They combine high-pressure resistance, chemical compatibility, and temperature stability for long-lasting service.
Materials – NBR, Viton, EPDM, Silicone
Applications – Aerospace, food-grade systems, hydraulic equipment
Features – High-pressure, chemical, and temperature resistance


Rubber Gaskets
Designed for reliable sealing under compression, vibration, and thermal stress, our rubber gaskets provide secure sealing where it matters most. We manufacture both die-cut and molded gaskets in a variety of thicknesses and elastomers to match your application.
Ideal for automotive assemblies, HVAC systems, electronics, and water treatment facilities, these gaskets resist aging, ozone, and fluid exposure. Our customization options allow you to specify material grade, thickness, and cut style for optimal performance.
Applications: Automotive, HVAC, electronics, water treatment
Customization: Thickness, material-grade, die-cut or molded
Butterfly Seals
Our Butterfly Seals ensure tight shut-off and long-lasting sealing performance that stands the test of time – especially in demanding valve systems. Designed for reliability, they resist chemical corrosion, high temperatures, and mechanical wear to maintain effective flow control.
Each seal is tested to deliver consistent performance and extended service life. They are widely used in power generation, chemical processing, and water treatment systems where durability under aggressive media and high-cycle conditions is essential.
Applications: Power generation, chemical processing, water treatment
Resilience: Resistant to chemical corrosion, heat, and mechanical wear


Wire Seals
Engineered for air tight and water tight protection in sensitive systems. They maintain performance under pressure, vibration, and extreme conditions to safeguard electrical connections and enclosures.
Commonly used in automotive electronics, aerospace, telecommunications, and electrical enclosures, our wire seals combine high-durability materials with precision manufacturing.
They resist moisture, dust, and environmental stress for dependable long-term protection.
Applications: Automotive electronics, aerospace, electrical enclosures
Performance: Sealing under pressure, vibration, and extreme conditions
