Product Description
High-quality Wear-resistant NBR/FKM Rubber DIN 3869 ED Seal
Premium Sealing Solutions for Extreme Conditions
Our DIN 3869 ED seals are engineered for high-demand industrial sealing applications, providing exceptional durability and precision sealing performance.
Product Core Features
- Industrial-Grade Materials: Available in NBR (oil-resistant standard) and FKM (high-temperature chemical-resistant) options
- Strict Compliance: Meets DIN 3869 ED standard for dimensional and performance consistency
- Excellent Wear Resistance: Reinforced structural design extends service life in dynamic/static applications
- Broad Applicability: Suitable for hydraulic, pneumatic, fluid handling, and industrial piping systems
- Ready-to-Install: Precision mold manufacturing eliminates additional adjustments, reducing installation costs
Product Overview
Our DIN 3869 ED seals are designed for high-demand industrial sealing applications. Manufactured from high-quality NBR (nitrile rubber) or FKM (fluorocarbon rubber), they ensure reliability under pressure, temperature, and chemical media conditions. These seals are suitable for standard ED-type grooves, offering static or low-speed dynamic sealing solutions, making them an ideal choice for hydraulic fittings, flange connections, and pipe sealing.
