Expert Custom Seal and Rubber Products Manufacturing Solutions

A line seal typically refers to a standard sealing product or existing product line designed for common dimensions, materials, and applications. A custom seal is engineered around specific operating requirements such as unusual geometry, pressure, temperature, media exposure, movement, or industry specifications. DSC supports both, offering standard products and custom solutions developed through design review, material selection, CAD, FEA, and testing.

Seals are often grouped into static seals, dynamic seals, and specialty or engineered seals. Static seals prevent leakage between non-moving surfaces, such as gaskets and O-rings in fixed joints. Dynamic seals work with moving parts, including rod, piston, and rotary applications. Specialty seals include custom-molded, metal-bonded, LSR, PTFE, or application-specific designs for demanding environments.

Yes. DSC brings customer design parameters to life using computer-aided design, finite element analysis, material expertise, and bench testing where appropriate. Custom solutions can range from modified O-ring geometries and washers to complex molded rubber shapes, diaphragms, gaskets, metal-bonded components, and application-specific sealing products for demanding industrial requirements.

DSC works with hundreds of compounds across major rubber types, including FKM, NBR, HNBR, XNBR, EPDM, ACM, VMQ Silicone, FVMQ, LSR, CR, ECO, IIR, SBR, FFKM, AEM, PU, TPU, and more. Material selection depends on media exposure, temperature, pressure, flexibility, wear resistance, regulatory needs, and expected service life.

DSC serves a wide range of industries, including automotive, aerospace, oil and gas, healthcare, food and beverage, water and sanitary, agriculture and construction, renewable energy, semiconductor, automated assembly, and general industry. Products such as O-rings, gaskets, diaphragms, LSR components, hydraulic seals, and metal-bonded rubber parts can be matched to each sector’s performance requirements.

Custom designs can be evaluated with CAD, finite element analysis, and bench testing under customer conditions to confirm product viability. DSC also has an ISO 17025 accredited lab for custom material development and testing. This helps verify whether the selected material and geometry can meet the expected sealing, durability, and environmental requirements.

Yes. DSC offers standard and custom O-rings in sizes from very small diameters to large-format applications, with options aligned to standards such as AS 568, BS 4518, GB/T 3452.1, JIS B2401, SMS 1586, metric, and JASO F404. Custom O-rings can be specified by size, material, tolerance, and application environment.

Helpful details include part drawings, dimensions, cross-section, application type, pressure, temperature range, media exposure, movement type, required material or certification, expected volume, and any current failure issues. If the material is unknown, DSC can help review performance requirements and recommend an appropriate compound or develop a custom material when necessary.
