Oil seals are normally made from a nitrile rubber, known as NBR. This is used because it is cheap, and plentiful, not because NBR is the best material for the job.

Although the cost of XNBR is almost twice that of NBR, the sophisticated technology used to make our oil seals enables us to put them on the market at highly competitive prices. In this way, the Ariete Customer enjoys the benefits of a very high quality product, which satisfies the most demanding requirements, at a competitive price.

This compound offers unique characteristics of resistance to abrasion, to high temperatures, and to the complex lubricants with numerous additives, which are used in modern forks as fitted to motorcycles and scooters.

Ariete ARI the original fork oil seals is the best you can get. This claim is justified by the quality of the materials used, and attention to detail in their design and manufacture. The ARI range has more than 170 different seal sizes. These cover more than 35,000 different motorcycle models with both traditional and upside-down forks. We have seals for classic 1960s telescopic forks extending through to the air forks now common both on- and off-road. ARI the original fork oil seals – perfection, from Ariete.

The reciprocating action of the fork tube against the seal subjects it to a notable degree of abrasion, which is complicated by the heat generated as a result of hydraulic displacement within the fork, plus the friction of the components involved. This mechanical wear and tear leads to accelerated ageing of the rubber which is also obliged to deal with the chemical action of the various additives in the lubricant.

Our technical staff have accumulated 70 years of experience in the rubber industry, and have spent many years looking for a better material for the manufacture of oil seals.

Ariete fork oil seals are different! The quality of their execution is matched by the unique nature of the material used: the carboxylated elastomer known as XNBR.
