The BULB-VAC tool comes with one 3/4" diameter static dissipative Buna-N vacuum cup. Operates similarly to a tweezer; squeeze the vacuum bulb; place the soft suction cup to the part to be handled; then squeeze and the part is firmly gripped. A second squeeze releases the part. These tools lift 0.25 lb. Applications include SMT parts, metal parts, plastic parts or any item with a smooth nonporous-surface. Can be used with any of the company’s rubber vacuum cups, ranging in size from 3/8" to 3/4" in diameter.
