Festo
1373812
Vacuum suction cup VASB-55-1/4-SI-B
The Festo 1373812 is a round, 1.5-fold protective bellows suction cup with a 55 mm diameter, a nominal width of 4 mm, and a 20 mm height compensation capacity. This transparent industrial component operates within a pressure range of -0.095 MPa to 0 MPa using atmospheric air, delivering a holding force of 110 N at its nominal operating pressure of -0.07 MPa. Weighing 29 g with a G1/4 vacuum connection oriented upward, it functions across an ambient temperature range of -40 °C to 200 °C and exhibits a moderate corrosion resistance class of 2 alongside VDMA24364 Zone III LABS conformity.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
