Eutsler Custom Elastomer Seal & Gasket Products
Introduction
At Eutsler Technical Products, we engineer and manufacture custom elastomer seals and gaskets designed to perform in the most demanding operating environments.
From high-pressure oilfield tools and chemical processing equipment to aerospace systems and industrial power units, our sealing products are precision-engineered, custom-compounded, and fully validated to ensure long-term reliability and leak-free operation.
Eutsler’s Enhanced Seal & Gasket Technology integrates custom elastomer formulation, advanced molding, bonding, machining, and inspection—all performed in-house under ISO 9001:2015-certified controls.
The result: high-integrity sealing products that meet your exact pressure, temperature, and chemical compatibility requirements.
Core Design Features
Application-Specific Compounds
- Elastomers custom-formulated for oil, fuel, steam, and chemical resistance
- Tailored hardness, compression set, tear strength, and rebound elasticity
- Optional dual-hardness or reinforced gasket structuresfor long-term sealing force retention
Precision Molding & Fabrication
- Compression, transfer, and injection molding for both flat and profile seals
- Bonded metal/fabric gasketsfor composite and dynamic environments
- Large-format molding for seals exceeding 36" OD (custom tooling available)
Dimensional & Surface Accuracy
- Tight dimensional tolerances per ARPM gasket standards
- Surface finishes optimized for compression, sealing, and adhesion applications
- Flatness and thickness controlled to ±0.005–0.010 in typical applications
Material & Compound Options
Eutsler compounds are designed from the molecular level for optimal sealing behavior under stress, temperature, and chemical exposure.
| Material Family | Examples | Key Attributes |
|---|---|---|
| Hydrocarbon-Resistant | NBR, HNBR, FKM, TFEP | Excellent oil, fuel, and gas resistance |
| Chemical & High-Temp | FKM, FFKM | Broad chemical resistance, 400–600 °F stability |
| Steam & Water Service | TFEP, EPDM, CSM | Excellent polar media resistance |
| General Purpose | NR, SBR, CR | High resilience and fatigue resistance |
| Low-Temp / Flexible | VMQ, FVMQ | Elasticity to –75 °F |
| Low Permeability | IIR, BIIR | Exceptional gas retention for vacuum seals |
Each elastomer system is verified through rheometry (ASTM D5289), tensile/elongation (ASTM D412), and compression set (ASTM D395) testing for predictable sealing performance.
Seal & Gasket Types
Eutsler designs and manufactures virtually every elastomer seal and gasket geometry, including:
- Flat & Sheet Gaskets – Precision die-cut or molded profiles for flange and cover sealing
- Profiled Compression Seals – Round, square, D-rings, X-rings, quad-rings
- Bonded Seals – Elastomer-to-metal or elastomer-to-fabric structures for load control
- Custom Molded Gaskets – Complex geometries, flanged seals, and composite interfaces
- Dynamic Seals – Shaft, piston, and rotary seals designed for low friction and wear
- Lip & Flange Seals – Multi-lip configurations for differential pressure sealing
- Encapsulated Gaskets – FEP or PTFE-lined elastomer cores for chemical barrier performance
Manufacturing & Processing Capabilities
- Molding: Compression, transfer, and injection molding with optimized vent and flow control
- Cutting: Waterjet, laser, and die-cutting for precision gasket outlines
- Bonding: Chemical and mechanical adhesion to metals, composites, or fabrics (ASTM D429 qualified)
- Machining: Grinding, and surface shaping for tight-tolerance applications
- Post-Cure: Controlled thermal cycles for dimensional stability and outgassing reduction

- Custom geometry to reduce over-compression and improve stress distribution
Gasket Groove Design
- Groove fill typically 70–85 %for static seals
- Chamfers or fillets used to reduce corner stress and extrusion
- Optional anti-extrusion backup ringsfor high-pressure sealing
Bonded Seal Assemblies
- Elastomer-metal bonding for static high-load flanges
- Controlled tie-layer chemistry for thermal expansion compatibility
- Fabric reinforcement for dimensional stability
