ROC

Carbon/Graphite Seal Faces

ROC Carbon manufactures carbon/graphite seal faces from your drawings or samples, using the same high-quality materials and tolerances that original equipment manufacturers use. Styles include both segmented and one-piece seals. ROC is experienced in machining intricate details such as flow channels and ports. Our lapping capabilities encompass both carbon and hard faces up to 20 inches in diameter and to a flatness as tight as 1 helium light band. We can insert the carbon seals in metal housings (machined by us or furnished by you) by heat shrink fitting or by using specialty adhesives.

We also provide a comprehensive mechanical seal repair service for worn seals.

Technical services

ROC Carbon’s engineering staff is available to help you evaluate seal problems and to recommend solutions involving seal geometry and material.
