Vesrah Oil Seals, many say in the field, do not leak. The secrets are selection of material and precision Japanese design and engineering. Material:Vesrah seals are made of the material specifically defined for Reciprocal motion oil seal by JIS B 2402-4 Standard. This material possesses much higher wear-resistance against reciprocal motions than materials used for oil seal for rotation, such as NBR or polyurethane rubber materials. Our material is a little more expensive than other materials used for oil seal (rotation)."But it does not LEAK !" Design:Vesrah seals are designed and manufactured through strict adherence to O.E. specifications; for example each seal lip is individually machined to give ideal contact.
