The O-rings used in Chemyx stainless steel syringes are Buna-N O-ring. The Buna-N/Nitrile/NBR seals offer good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others. The Buna -N O-ring also offer superior abrasion and tear resistance, and are best for heavy-duty industrial applications. The operational temperature range of the O-ring is from -31°F to 250°F (-35°C to 121°C).
