|For use with Aeroquip 491 fittings. These tools are recommended to avoid damage to the sealing surface and to properly support the inner tube. Note: These are Aeroquip Factory Mandrels, which are highly recommended for best results.|
Good tool, well built and works as it should, just very overpriced. Lost a star for high price.
This fitting is made to be used specifically with the 303 series hose. The 666 series hose will take either the F66000 or AE21502 series fittings.
