Fel-Pro公司生产的标有条型商标的发动机气阀室密封垫(右图)和气缸盖密封垫,通过印在上面的兰色条纹很快就能把它同其它一些看似相象但质量并不相同的密封垫区分开来。Fel-Pro公司声称那些冒牌的或以橡胶作内衬的密封垫常常使用的是低等材料。因其材料颗粒之间留有空隙,故而漏气。该公司还声称“兰条”牌密封垫材质的颗粒大小,颜色和分布都很均匀,因而密封效果极好,绝不会泄漏。 Bar-engine engine valve chamber seals (pictured right) and cylinder head gaskets made by Fel-Pro can be quickly and similarly identified with other The quality is not the same seal to distinguish. Fel-Pro claims low-grade materials are often used for fake or rubber-lined gaskets. Due to the gap between the material particles left, so the leak. The company also claims that the “Lantern” brand gasket material is uniform in particle size, color and distribution, and therefore seals well and will not leak.
