Nitrile (NBR / Buna-N) O-rings have good resistance to mineral oils, greases and fuels for general oil sealing applications. SBR O-rings are cost-effective for water, dilute acids and non-oil medium sealing. Both are widely used in hydraulic, pneumatic, automotive, general machinery, pump & valve and construction equipment for static and low-speed dynamic sealing.
Our HNBR O-rings deliver reliable sealing under tough working conditions. Superior resistance to oil, fuel, heat, ozone and wear. Temperature range: -30℃ ~ 150℃. OEM & ODM supported, various sizes, colors and hardness options. Stable quality, competitive factory price, fast sample delivery.
15×2.4mm 70A EPDM O-rings are well known for good water resistance and anti-aging property. They are reliable sealing elements for automotive and sanitary system applications.
Buna-N NBR O-rings feature good oil and abrasion resistance, cost-effective for hydraulic, fuel and lubrication sealing applications.
Nitrile Rubber O-Rings (NBR / Buna-N O-Rings) are the most widely adopted standard elastomer seals for oil, fuel and hydraulic fluid sealing. Made from nitrile butadiene rubber copolymer, these circular rubber gaskets deliver balanced mechanical performance, excellent petroleum resistance and cost-effectiveness for both static and dynamic sealing.
