Factory supplied NBR O-Ring to Nigeria Factories

Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging – often a key advantage over natural rubber.

Technical Data Sheet

Application Area

Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.

Good day,I am linda from SBT Rubber Products CO.,LTD,the company was established in 2001,we are specialized in production of oil seals and O-rings.
We are factory,and we have professional engineers to ensure the quality of the products.Below is the introduction of our oil seals:
Seals Types:
TA TB TC
SA SB SC
KA KB KC
VA VB VC
The material of our oil seals:natural rubber(NR),nitrile rubber(NBR),hydrogenated nitrile rubber(HNBR),fluororubber rubber(Viton rubber)(FPM),silicone rubber(ACM),styrene butadiene rubber(SBR)，polyurethane(PU),Teflon(PTFE),EPM/EPDM.
Rubber O-rings: nitrile rubber, natural rubber, Viton and silicone rubber; With resistance to oil, high temperature, high pressure, corrosion,acid and alkali, wear resistance and good elacticity characteristics; O-rings are applied for machinery sealing, automotive sealing, especially in the pressure transmission system. O-rings have a circular section, an annular rubber rings, and are mainly used for the static conditions of the machinery to prevent the leakage of liquid and the gaseous medium. The initial compression of the aspects of the radial or axial direction at the time of installation, increase the initial sealing capacity of the O-rings themselves.
Silicone rubber O-rings,which without smell and colour,can used in the process of food.
