Viton (FKM) offers superior resistance to a wider range of chemicals and can withstand much higher temperatures, typically up to 200 deg C, but is more expensive.</p> <strong>The label says ‘WAS’ but the seal is marked ‘TC’. Are they compatible?</strong><br><p>Yes, WAS (DIN 3760 Form A) and TC are designations for very similar types of seals: a rubber-covered metal case with a spring-loaded sealing lip. They are generally considered interchangeable for most applications.</p> <strong>What is the purpose of the garter spring?</strong><br><p>The garter spring is a coiled steel spring that fits into a groove in the sealing lip. It applies a constant, uniform radial force, pressing the lip against the shaft to maintain a tight seal, even with minor shaft imperfections, thermal expansion, or wear over time.</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
