Why Choose Vulcanized Encapsulated O-Rings: The ROW, INC. TFE-O-SIL® Advantage

In the world of industrial sealing solutions, the integrity and reliability of O-Rings are paramount. At ROW, INC., we understand the critical role that O-Rings play in a wide range of applications, which is why we emphasize the superiority of vulcanized encapsulated O-Rings, particularly our TFE-O-SIL® range.

The Problem with Cyanoacrylate in O-Ring Manufacturing

Many manufacturers opt for CYANOACRYLATE (commonly known as quick glue) to join the ends of the Viton™ cord in encapsulated O-Rings. While this might seem efficient, it introduces several problems, especially at elevated temperatures.

Problem A: Risk of Contamination

The use of cyanoacrylate introduces a foreign material that may permeate through the FEP or PFA jacket, leading to potential contamination. This is a significant concern in industries where purity and cleanliness are non-negotiable, such as in pharmaceuticals and food processing.

Problem B: Chemical Deterioration

Certain chemicals can permeate and attack the glued joint, leading to premature seal failure. This is a critical issue in chemical processing environments where O-Rings are exposed to a variety of harsh substances.

Problem C: Temperature Sensitivity

The bond created by quick glue is significantly weakened with a rise in temperature. Approaching 400°F, the elastomer shrinks, and the joint separates, leaving a gap between the ends of the Viton™ cord. This gap is a direct path to leaks and system failures.

Problem D: Durability During Installation

When heating and stretching a glued O-Ring to fit over a shaft, the bond may break. This not only complicates the installation process but also raises questions about the long-term reliability of the seal.

The ROW, INC. Solution: TFE-O-SIL® Vulcanized Encapsulated O-Rings

At ROW, INC., we address these issues head-on with our TFE-O-SIL® vulcanized encapsulated O-Rings. Unlike the quick-glue method, our vulcanization process uses a fully curable fluorocarbon-based adhesive, ensuring a robust and durable bond that withstands high temperatures and harsh chemical environments.

Test the Difference Yourself

Don’t just take our word for it. We encourage you to conduct your own test. Place an O-Ring in an oven at 350°F for 15 minutes. If it’s a glued O-Ring, you’ll notice the splice separating, creating a visible gap. This simple test highlights the superiority of the vulcanized bond in our TFE-O-SIL® O-Rings.

Choose Reliability, Choose ROW, INC.

In industries where failure is not an option, choosing the right O-Ring is crucial. With ROW, INC.’s vulcanized TFE-O-SIL® encapsulated O-Rings, you’re not just buying a product; you’re investing in peace of mind.
