Dichtungsscheiben (Seal Washers) A seal washer that sits between a bolt head or nut and a mating surface to create a reliable, leak resistant seal. Designed to suit a range of fastener assemblies, these washers help maintain seal integrity and protect threaded joints. Key benefits - Reliable sealing: Compresses to fill small gaps and imperfections, helping prevent leaks at the fastener joint. - Enhanced joint integrity: Shields threads and sealing surface from contact wear and corrosion, supporting longer service life. - Easy installation: Simple, drop-in component that pairs with standard bolts and flanges without special tools. - Versatile material options: Available in different materials to match chemical exposure, temperature range, and fluid compatibility. Function and performance - Purpose: Act as a seal between a fastener and a mating surface, providing a pressure resistant seal under normal operating conditions. - Sealing reliability: Maintains closure as the joint is tightened, helping to reduce maintenance related to leaks. - Durability: Selected materials offer resistance to standard sealing challenges in typical mechanical and plumbing applications. - Reusability: Intended for single use with the same joint; inspect and replace if damaged or worn. Compatibility and sizing - Fit: Suitable for standard bolt and flange interfaces common in mechanical, automotive, and plumbing assemblies. - Sizing guidance: Choose by inner diameter to match the bolt shank, outer diameter to cover the sealing surface, and thickness to achieve the required seal compression. - Sizing variants: Available in multiple outer/inner diameter combinations and thicknesses to match common fastener sizes and fixture designs. - Compatibility note: Material choice and dimensions vary by model; refer to the product label or data sheet for exact specifications. Material and specifications - Material availability: Offered in a range of materials to suit different conditions. Specific material for each model is listed on the product documentation. - Selection considerations: Select material based on chemical compatibility, temperature exposure, and the type of fluid or gas being sealed. How to choose - Determine bolt size: Confirm the bolt diameter and thread standard (metric or imperial) to select the correct inner diameter. - Assess the sealing surface: Ensure the outer diameter fully covers the sealing area without overhang. - Consider operating conditions: Temperature, pressure, and chemical exposure guide material choice and thickness. Installation tips - Prepare surfaces: Ensure mating surfaces are clean, flat, and free from debris prior to installation. - Correct orientation: Place the seal washer between the fastener and the sealing surface so that the sealing area is properly engaged. - Do not reuse damaged seals: Replace any washer that shows signs of deformation, tearing, or wear. - Follow torque recommendations: Tighten to the recommended torque for the joint to achieve proper compression without damaging the washer or surface. Applications and use scenarios - Automotive and machinery assemblies: Seals around engine brackets, sensor mounts, or fluid line connections where a reliable joint seal is required. - Plumbing and fluid systems: Seals on pipe or hose connections where a tight seal against leakage is essential. - Equipment housings and enclosures: Seals between fasteners and enclosures to protect against ingress and maintain enclosure integrity. Note - Material and dimension specifics depend on the exact model. For precise fit, verify inner diameter, outer diameter, thickness, and material listed on the product label or datasheet before ordering. This description focuses on function, compatibility, size, material, and performance, with practical use scenarios to assist selection and application without unnecessary embellishment.
