Review on 🔧 Maximize Performance with the Neiko Tools 407-Piece Rubber O-Ring Assortment Kit - 32 SAE Sizes by Tom Oberhue

THESE O-RINGS WILL NOT PREVENT LEAKING. I bought these to replace a few different o-rings in camper hydraulic jacks, but they leak just as badly as the old ones I'm trying to replace (even with no stress on the jacks!). The material quality of the O-rings is poor as they break easily and are too soft. My micrometer couldn't give a reliable dimensional measurement with an acceptable tolerance because the pressure resistance is small, but all of the cross-sectional measurements were on the low end of the tolerance scale (i.e. probably too thin). After many frustrating hours, I went to the local hardware store, bought o-rings that were exactly the same size, and the leaks stopped completely. I'm returning these o-ring kits to Neiko as I can't afford to waste time on this low quality junk. NEVER AGAIN. The manufacturer's product description reflects false advertising.
