Yes – Some of the more common materials we use are 13 Chrome and Super 13 Chrome, but we have worked with other types in the past. Some common elastomers we use to upgrade our tools with are: HSN, Viton, EPDM, ECNER HSN, ECNER Aflas, ATR, and VTR seal arrangements. We also offer electroless nickel plating on most of our product line. This offers protection against corrosive downhole environments at a much lower cost than exotic materials.
