    Custom AFLAS O-ring to Skyrocket Your Business

    AFLAS Transmission Seals for Automotive

    AFLAS has a high-chemical resistance against transmission oils, additives in engine oils, and heat-resistant greases. When you use FKM in this fluid, it will be hardened but when you use AFLAS, it can maintain its elasticity longer.

    AFLAS for Cable Application

    AFLAS polymers have excellent heat resistance and electrical properties. It is widely used for rubber cable in electric appliances, bullet trains, and automobiles.

    AFLAS Turbo Hose

    AFLAS can be excreted into hoses and provide great chemical resistance which is impossible with FKM. Aside from automotive applications, it can be also used in the chemical processing industry.

    • It’s always nice to have o rings on hand because you never know when you might need one, used them on a tractor hydraulic pump went on easy, and did what it was meant to do. YOSON’s AFLAS products have good quality and high-standard.

    • This is a very nice O-Ring from YOSON and works well. I’ve installed 4 of these on my different garden sprayers, which all used the same size O-Ring and they seal perfectly. Highly recommended.

    • AFLAS of Yoson is just as good as the Ford gaskets and quality built, my mechanic guy was pleased I chose these AFLAS rather than some of the crap ones that some people bring to his shop. My mechanic said next time he will try to make some orders from YOSON.
