The KACO Oil Seal 25x38x7/8 DGS NBR is engineered for rotary shaft applications where dependable sealing performance, lubricant retention, and protection against contaminants are essential. It is commonly installed in electric motors, industrial gearboxes, hydraulic pumps, compressors, conveyor systems, machine tools, agricultural equipment, and OEM rotating machinery.

The DGS Profile features a precision metal case, a spring-loaded primary sealing lip, and an auxiliary dust lip. This double-lip construction effectively retains lubricants while preventing dust, dirt, moisture, and airborne contaminants from entering the sealing system. The precision metal case ensures dimensional stability, secure housing fit, and long-term reliability.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this oil seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants

NBR offers outstanding flexibility, abrasion resistance, and durability, making it one of the industry's preferred sealing materials for general-purpose rotary shaft sealing.

With dimensions of 25 × 38 × 7/8 mm, this oil seal is widely used in electric motors, industrial gearboxes, hydraulic pumps, compressors, conveyors, agricultural machinery, machine tools, and OEM equipment requiring reliable metric rotary shaft sealing.
