Gaskets are usually the first thing to fail on a plate exchanger, and for good reason — they’re the wear component, expected to seal repeatedly against pressure, temperature cycling, and chemical exposure over years of service.
Getting the gasket material wrong is a common and costly mistake. The wrong elastomer for your process fluid can degrade quickly, cause leaks, or contaminate the process stream — and gasket profiles vary enough between manufacturers that a close visual match doesn’t guarantee a proper seal.
Elastomer choice depends entirely on what the gasket actually has to withstand. NBR (nitrile) handles general oil and water duties at moderate temperatures; EPDM suits steam, hot water, and many chemical services but degrades quickly in contact with mineral oils; Viton (FKM) holds up in high-temperature and aggressive chemical environments where NBR and EPDM won’t survive; and PTFE-coated EPDM combines EPDM’s base elasticity with PTFE’s near-universal chemical resistance, for duties where the process fluid would otherwise attack the elastomer directly. Choosing based on price alone, without checking actual chemical compatibility, is one of the most common causes of premature gasket failure.
We help confirm the correct gasket material and profile for your fluid and operating conditions, then connect you with a supplier who can deliver the right part — rather than leaving you to source a lookalike gasket and find out only after it’s installed whether it actually holds.
