FAQ

NBR (Nitrile Butadiene Rubber), as used in this seal, is excellent for applications involving oils and fuels at moderate temperatures (typically -30 deg C to 100 deg C). FKM (Viton) offers superior resistance to higher temperatures and a broader range of chemicals but is generally more expensive.

Standard Simmerring designs like this are typically suitable for low-pressure applications, up to approximately 0.5 bar. The 'U' in the type designation (BAFUD4SLX7) often indicates suitability for some pressure, but for high-pressure systems, a specially designed seal would be required. Always consult the manufacturer's datasheet for your specific pressure requirements.

The cure date is the date of vulcanization (manufacturing). For NBR seals, the shelf life is typically 7-10 years when stored correctly (away from light, heat, and ozone). While this seal is past the typical shelf life, its performance is often unaffected if it has been stored in its original, sealed packaging, which protects it from environmental factors.
