The 9700 is our heaviest production seal. We build it from solid 316L bar stock, machine to 0.0005-inch tolerances, and pressure-test every unit to 50 psig before it leaves Cherry Hill. It runs on the kind of service that eats lesser seals: chlorinated solvents, sulfuric scrubber bottoms, fly ash slurry, lithium hydroxide. If you have a sealing problem nobody else will quote, start here.
