SINOCMP Multi Assortment Vehicle Repair Review

Purchased to install a short switch on my truck. I had to drill some big holes in the floor and didn't want water to get in. The problem is solved!

Organized set is great. When I removed the expansion valve on my Honda Civic I found that the original o-rings are thicker so I reused them in place of this product. It may not be true for you, and this is good kit. I saved it to see if I need it for another repair.

Summer came and I needed to replace a faulty compressor and with it most of the other components in my car's air conditioning system. I replaced all of the exposed o-rings with these. After reassembly the vacuum held up great on my new system and three weeks later my AC is still blowing cold. Good product!

I changed the fuel injectors on a 2001 Toyota Sienna Van and need new O-rings. I tried using old o-rings but they didn't seal properly and had a gas leak/smell. This kit is the right size and after replacing all the old top and bottom o-rings everything is fine - no more leaks or smell of gas :). Much cheaper than buying OEM rings or buying aftermarket rings per piece.

At least at the time of purchase and review, the case description of this product stated that it was HNBR. This is not ordinary (unsaturated) nitrile rubber. A visual comparison with the real HNBR reveals this. They are much brighter than HNBR; The hydrogenation process causes HNBR to darken. I also tested the resiliency of these materials and they failed long before I tested two samples of HNBR. It's a shame I didn't find out about all this before the return deadline!
