Dayco Poly-V Belt 7PK1640
Dayco® developed the first Poly-V BELT® or Multirib belt for the Ford Mustang in the USA in 1979. This 7-rib serpentine belt with 1640mm length sets the industry standard for automotive drive belt performance.
Key Features
Advanced Design
- Multiple rib and flat design provides better belt to pulley contact for less slippage than conventional V-belts
- Multiple ribs eliminate the need for matching and allow for controlled slippage in overload situations, such as when an A/C compressor engages
- Grooved design provides flexural stress relief for increased flexibility in both normal and backside bending
Superior Construction
- Engineered with high-grade EPDM (ethylene propylene diene Monomer) compounds for enhanced durability
- Rubber impregnated fabric backing maximizes load carrying capability and minimizes noise
- Specially treated cord is saturated with formulated treatment that ensures length and belt stability for the life of the belt
- Heavy duty construction provides additional integrity without sacrificing flexibility or belt-to-pulley compatibility
Environmental Resistance
- Built to resist heat and harsh under hood environments
- Grooves render the belt less susceptible to environmental factors such as dust and splash induced slip
- Designed for both over-the-road and off-road conditions
