Optimus Hardline Compression Fitting Satin Silver / 12mm / 6 Pack with Wrench

The best hardline fitting ever made, period. The patent-pending Optimus gasket design is exponentially stronger than any o-ring design ever made. Our 1/8 (3.2mm) thick gasket provides huge surface area to clamp the hard tubing.

With ultra-precision machining, extreme corrosion resistant Pro-XE nickel, plasticizer-free o-rings and super clean looks, Optimus fittings are so good we back them with a 10 year warranty.
