No Leakage in 10 Years with Kalrez Perfluoroelastomer Seals

Kalrez Perfluoroelastomer SealsDramatic increases in instrument performance and reliability have been achieved where original PTFE gasket seals have been replaced with Kalrez® custom gaskets from the DuPont™ Performance Polymers range of products.

A Finnish manufacturer of process refractometers was utilizing process media at temperatures ranging from -20° to +220°C and pressures from 0.7 bar to 25 bar. These aggressive operating conditions resulted with the PTFE seals needing to be regularly replaced on a 6-12 months operating cycle.

However, after the seals were replaced by Kalrez® custom gaskets, there was no experience of fluid leakage over a 10 year period, even though the sealing products were subject to permanent in-line fluids immersion during this period.

VIDEO: Diagnosing Damaged O-Rings

Making sure you have the right O-ring is critical to avoiding leakage in your product or machinery.  But if an O-ring fails, do you know how to diagnose the problem?  Can you tell the difference between wear and compression set problems in a flattened o-ring? Identifying the right root cause is critical to solving the problem of damaged O-rings. Watch the video below to learn how to diagnose some of the most common o-ring failure modes.

For more information on failure modes, check out the Leak Troubleshooting Tool in the support section of the Parker O-Ring Division website.  Please contact us if you have any questions.

Avoiding Spiral Twist with the Quad-Ring Brand Seal

Quad-Ring Brand SealFounded in 1945, Minnesota Rubber and Plastics is a pioneer in the design and production of four-lobed seals with the Quad-Ring® Brand seal design.

Today these seals are used around the world for a wide variety of static and dynamic sealing applications.

Avoiding Spiral Twist

To minimize breakaway friction, an O-Ring groove must be wide enough to allow rolling or twisting of the seal. In the long stroke of a reciprocating seal application, this twisting action can strain and eventually tear the rubber, causing a failure mode known as spiral twist.

To prevent spiral twist, the Quad-Ring Brand seal four-lobed configuration is designed to withstand the distortion and extrusion often caused by high or pulsating pressure. To accommodate these forces, a Quad-Ring Brand seal uses a narrower groove than a comparable O-Ring seal.

What Causes O-Ring Cracking?

o-ring crackingHere at Gallagher Fluid Seals, we provide O-rings to almost every industry you can think of: fluid power, chemical processing, aerospace, energy oil & gas, life sciences, pulp & paper, etc.

The thing with an O-ring is as long as it’s doing its job, you never really even know it’s there. It is only when an O-ring starts to fail and a leak develops that you investigate the problem.

One of the key causes of O-ring cracking is ozonolysis (ozone cracking). Ozone cracking occurs mostly with Nitrile Rubber o-rings (nitrile, buna, buna-N).
