The KACO 15x23x4.5/7.5 DFD FKM (Viton®) Oil Seal is engineered for rotary shaft applications operating under elevated temperatures, high rotational speeds, and aggressive lubricants where conventional NBR seals may not provide sufficient service life.

The DFD Profile incorporates a precision metal case, spring-loaded primary sealing lip, and auxiliary dust lip to provide outstanding lubricant retention while protecting the system against dust, moisture, and abrasive contaminants. The specially designed profile offers stable sealing performance with minimal friction, making it ideal for compact, high-speed rotating equipment.

Manufactured from premium FKM (Fluoroelastomer, commonly known as Viton®), this seal offers excellent resistance to:

• Synthetic oils
• Mineral oils
• Automatic transmission fluid (ATF)
• Hydraulic oils
• Gear oils
• Engine oils
• Fuels and diesel
• High-temperature lubricants
• Many industrial chemicals

FKM provides superior resistance to heat, oxidation, ozone, weathering, and chemical attack compared to conventional NBR, making it the preferred sealing material for demanding automotive and industrial environments.

With dimensions of 15 × 23 × 4.5 / 7.5 mm, this oil seal is commonly used in automotive engines, transmissions, electric motors, hydraulic pumps, industrial gearboxes, machine tools, and OEM equipment requiring compact high-performance sealing solutions.
