5978 ShorTec Dual Durometer 1-1/2 Bellow 30mm Vacuum Cup

Dual durometer-style vacuum cups are considered to be the best performing polyurethane cup and are now available at a lower price. These blue dual durometer cups are comparable to the brand-name OEM green and yellow cups in that they use mark-free and long-lasting polyurethane, have the same dual-shore rating, and fit the same size nipples.
