Vesrah fork oil seals have been developed using a high performance rubber which provides resistance to wear, minerals, oils and heat. Each seal lip is individually machined to give ideal contact between seal and stanchion resulting in an excellent sealing performance. Vesrah seals are made of material specifically defined for reciprocal motion oil seals by JIS B 2402-4 Standard. This material possesses much higher wear-resistance against reciprocal motion than materials used for oil seals for rotation, such as NBR or polyurethane rubber materials. Our material is a little more expensive than that used for other oil seals (rotation), but it does not LEAK. Vesrah seals are designed and manufactured with strict adherence to OE specifications.
