ACDelco’s patented Advanced Technology belt design incorporates EPDM rubber.
- Resists penetration of water, acids and ozone
- Broad temperature tolerances
- Stays soft and pliable longer than traditional belt materials like neoprene.
Rubber that turns hard can cause belt squealing and a shorter belt life
