At Exactseal, we specialize in the manufacturing of high-quality, custom rubber parts, including our top-of-the-line Fabric Reinforced Diaphragms.

Fabric Reinforced Diaphragms are flexible seals (membrane) with fabric (Nylon, Nomex/Aramid, Dacron, Kevlar & other fabrics) sandwiched between two layers or applied on either side of the membrane so that they transmit force and pressure between two sides in high-pressure applications. They are engineered to prevent leakage and control pressure or measure pressure in combination with pressure gauges within chambers while preventing damage to instruments. These diaphragms are reinforced with fabric to enhance their durability and longevity, ensuring they can withstand demanding applications and environments.

The fabric reinforcement in our diaphragms provides superior strength and flexibility, making them resistant to wear and tear, even under extreme pressure or temperature conditions. This reinforcement also enhances the diaphragm’s stability, ensuring it maintains its shape and functionality over time.

Our Diaphragms are manufactured using a variety of high-quality materials, including Silicone, EPDM, Nitrile (Buna N), FKM (Viton), and Neoprene. These materials are chosen for their excellent resistance to a wide range of chemicals and temperatures, ensuring our diaphragms can perform reliably in various applications.

Quality is at the heart of everything we do at Exactseal. Our Fabric Reinforced Diaphragms undergo rigorous testing to ensure they meet the highest standards of quality and performance. We are committed to delivering products that not only meet but exceed our customers’ expectations.

At Exactseal, we understand that every application is unique. That’s why we offer custom-made Diaphragms tailored to meet your specific requirements. Our team of experts works closely with you to understand your needs and design a product that delivers optimal performance.
