DIN 2353-WD Captive Seal (ED Seal)
Most popular Metric Hydraulic Fittings
Description
Reviews
Integrated Structure: The ED Seal is an elastomeric ring (commonly made from materials like Nitrile Butadiene Rubber - NBR) that is securely housed within the fitting body. This captive design prevents displacement during installation, ensuring consistent sealing performance.
Sealing Mechanism: When the fitting is tightened, the ED Seal compresses against the tube's outer surface, creating a tight, leak-resistant seal. This mechanism is particularly effective in high-pressure applications where maintaining system integrity is essential.
Compatibility: The dimensions and design of the ED Seal are standardized according to DIN 2353 and ISO 8434-1, ensuring compatibility with various fittings and tubes that adhere to these standards.
