Description: Suction Cup with 2½ Bellows - VGSTM3010 BX52P are suitable for level adjustment and for uneven and porous surfaces, such as corrugated boxes/ containers. The bellows and sealing surface are available in different durometers. This gives the cup strength and stability as well as the flexibility to conform to uneven surfaces. The Duraflex material is non-marking, with a separate G3/8' male suction cup fitting. A filter support ring in the cup keeps dust out of the system. The filter materials are polyester (PES41/14) and thermo-plastic-urethane (TPE).
