WHAT YOU NEED TO KNOW
Material determines chemical compatibility Standard durometer is 70 Shore A
Wrong material = catastrophic seal failure
PRODUCT OVERVIEW

Candy 20 Blue Ring is a fan with a 120mm blue LED ring.<br>Thanks to this system the blue led light is more uniform than traditional Led systems, thus achieving a better visual effect by offering a bright and uniform illumination.<br>These fans have 7 blades in black that favor a better flow of air inside the chassis and optimize the static pressure, giving a great performance.<br>Its design with hydraulic bearing guarantees silent operation of the fans. This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5330-00-399-0230, indicating validated use in U.S. government and defense logistics supply chains.

O-RING / SEAL — MATERIAL DETERMINES APPLICATION ID: — CROSS-SECTION CS: — SPECIFICATION Material: — Durometer: — Temp: — PN: 51798 MFR: UNYKAch ⚠ VERIFY BEFORE ORDERING Wrong material = failure. Viton for oil/fuel, EPDM for water/steam, Buna-N for general purpose, Silicone for food-grade. Chemical incompatibility causes swelling, brittleness, or rapid degradation ✓ BROKER TIP Durometer (hardness) affects sealing pressure tolerance. Higher Shore A = harder = higher pressure. Standard durometer is 70A — verify if application requires different hardness PARTSTABLE TECHNICAL DRAWING — NOT TO SCALE
