Nuclear Energy Sealing Solutions for Power Plants

Power plant applications may use O-rings, gaskets, packings, PTFE products, diaphragms, back-up rings, bonded seals, and custom-molded rubber components. The right choice depends on pressure, temperature, media exposure, gland geometry, motion, and maintenance requirements. DSC supports both standard and custom solutions, including material selection and engineering review for demanding industrial sealing environments.

Yes. DSC can take customer design parameters and develop custom sealing solutions using computer-aided design, finite element analysis, compound selection, and bench testing under customer conditions when needed. If a suitable compound is not already available, DSC can help custom develop and test materials through its ISO 17025 accredited lab capabilities.

DSC provides access to hundreds of compounds across major rubber types, including FKM, NBR, HNBR, XNBR, EPDM, ACM, VMQ, FVMQ, LSR, CR, ECO, IIR, SBR, FFKM, AEM, polyurethane, and TPU. Material selection can be guided by chemical compatibility, temperature range, compression set, hardness, wear resistance, and performance requirements.

DSC offers standard and custom O-rings, including sizes aligned with international standards such as AS 568, BS 4518, GB/T 3452.1, JIS B2401, SMS 1586, metric, and JASO F404. Available sizes range from very small profiles to large diameters, with precise tolerances used to help prevent leakage in the final assembly.

DSC supports validation through its fully equipped, ISO 17025 accredited lab for custom material development and testing. Designs can also be bench-tested under customer conditions to evaluate product viability. This helps customers assess whether the selected geometry and compound are appropriate before committing to broader production or installation programs.

Yes. DSC offers PTFE products and rubber-to-PTFE bonded components for applications requiring chemical resistance, low friction, or specialized surface performance. The company also supplies metal-bonded rubber seals using metals such as stainless steel, carbon steel, copper alloys, and aluminum alloys combined with rubber materials including NBR, FKM, EPDM, HNBR, and silicone.

DSC offers multiple products that support high-pressure sealing, including custom washers, O-rings, back-up rings, gaskets, and specialized molded components. Back-up rings can fill extrusion gaps in O-ring glands, increasing pressure capability in compact designs. Proper material hardness, gland design, tolerances, and compound selection are all considered when addressing leakage risk.

Start by gathering the application details: operating pressure, temperature range, media exposure, dimensions, motion type, expected service life, and any applicable material or industry specifications. DSC can then review whether a standard product fits or whether a custom-molded solution, compound recommendation, CAD review, or testing pathway is more appropriate.
