Advanced Aircraft Seal Services for Aerospace Industry

Aerospace applications commonly use elastomeric seals such as O-rings, gaskets, packings, diaphragms, backup rings, and metal-bonded rubber seals. Material choices may include FKM, FVMQ, VMQ silicone, NBR, HNBR, EPDM, PTFE-bonded constructions, and other compounds depending on temperature, fluids, pressure, motion, and sealing geometry.

DSC supplies a wide range of molded rubber sealing components suitable for aerospace use, including standard and custom O-rings, gaskets and packings, precision diaphragms, metal-bonded rubber seals, backup rings, X-rings, washers, and custom-molded shapes. The team can also support material selection and custom design parameters for specialized assemblies.

Yes. DSC supports custom sealing solutions by working from customer design parameters and using tools such as computer-aided design and finite element analysis. When needed, designs can be bench-tested under customer conditions to help confirm product viability, and custom material development may be supported through the ISO 17025 accredited lab.

DSC offers access to hundreds of compounds across rubber types, including FKM, NBR, HNBR, XNBR, EPDM, ACM, VMQ silicone, FVMQ, LSR, CR, ECO, IIR, SBR, FFKM, AEM, polyurethane, and TPU. Material selection depends on chemical exposure, temperature range, pressure, flexibility, wear resistance, and certification requirements.

O-rings are often used for compact circular sealing grooves, gaskets and packings are commonly selected for static surfaces or custom profiles, and diaphragms are designed for flexible movement in pumps, actuators, valves, regulators, and compressors. DSC can help evaluate geometry, motion, pressure, media, and material requirements before recommending a sealing approach.

DSC offers components that can support higher-pressure sealing challenges, including backup rings that complement O-rings by filling extrusion gaps and increasing pressure capability. Washers, gaskets, metal-bonded seals, and custom designs may also be engineered for specific pressure and leakage requirements, depending on the application environment.

Both options are available. DSC supplies standard components, including O-rings sized to major international standards, and also supports custom geometries, material selection, and tooling for application-specific sealing needs. With more than 8,000 tooled gasket and packing articles, DSC can often combine catalog availability with custom engineering flexibility.

Start by sharing drawings, dimensions, operating conditions, media exposure, temperature range, pressure, motion type, quantity needs, and any required material specifications. DSC’s technical team can review the application, discuss standard or custom options, recommend suitable compounds, and help determine whether testing or custom development is appropriate.
