DESCRIPTION: CHO-SEAL flat washers are stocked in hundreds of different sizes. I.D.s and O.D.s are available in increments of 1/64 in. (0.41 mm). CHO-SEAL 1215 material provides the highest levels of shielding effectiveness; CHO-SEAL 1285 material the best combination of shielding effectiveness, corrosion resistance, weight, cost and use temperature range; and CHO-SEAL 1298 the highest level of corrosion resistance. Precision flat washers can also be produced by cutting hollow O-shape extrusions. Tolerances on I.D. and O.D. would be tighter than those of the stocked
flat washers.
