Factors in the selection of the tip attachment

Smooth suction and release of an object depends greatly on the hole aperture, material and shape of the tip attachment selected. Ultra-light and very small parts and components, that have almost no weight, are very difficult to release smoothly.
In such cases, a syringe-type attachment with a very small aperture should be selected, and the air volume adjustment screw fully loosened or removed altogether for the best effect.
On the other hand, when handling heavier objects, a rubber pad or spatula type attachment will allow sure suction and transport. Note that the suction strength shown in the catalogue is based on DAP-12S. Actual conditions will differ, depending upon the suction strength of the actual vacuum source, and the contours of the object being handled and its surface roughness.
Our standard attachment lineup has been enriched by the addition of PEEK made conductive tips that counter electrostatic charge and can be used safely with electronic parts and components.
From our wide ranging product offerings, select the attachment that best meets your needs to guarantee highly reliable handling.

Standard tip attachments

Metallic tip attachments

Tip attachments are plated with low cadmium brass, offering excellent heat resistance at the lowest cost.

The lineup covers tip attachments comprised of 3 different materials with 17 different hole diameters for suction of all micro parts such as spheres, rods, plane boards and washers.
Attachments made from different materials have different features, and you can choose the attachment best suited to your needs and application.


The front section is a soft resin, and an object will not be scratched when manipulated. Also, the attachments have improved chemical resistance.

PEEK conductive tip attachments

The Polypenco PEEK resin is compounded with carbon for electrostatistic protection, and its conductivity has been improved. These attachments are best suited for manipulation of very small electronic parts and devices that are very sensitive to static electricity. [Volume resistivity value: 105-6Ω.cm]

SUS syringe-type attachments

  • PDF Data
  • DXF Data
Our syringe-type attachments use a polished and chamfered stainless steel pipe as the suction surface.
A minimum hole diameter of φ0.1 is available for handling ultra-light micro-components. With the use of the Air Pit air volume control screw, suction and release can be made very smooth indeed. Straight type, 45° angle type and elliptical suction hole types are available.

The syringe-type attachments with elliptical holes are appropriate for the suction and manipulation of long and thin cylindrical objects such as dowel pins.

Conductive rubber pad attachments

  • PDF Data
  • DXF Data
Attachments with rubber pads are useful for suction and manipulation of relatively large and heavy objects. The hard rubbers do not deform easily and the suction hole diameters are large. For electrostatic protection, the silicone rubber is compounded with the carbon to improve its conductivity. [Volume resistivity value: 5 Ω cm]
Because of its high adhesion capacity, the rubber can be used to maintain the suction force of an object. You can safely use rubber pad attachments to manipulate lenses and prism glasses. (If you cannot release the object smoothly, loosen the airflow adjustment screw of the air pit.)

Spatula-type attachments have been designed for suction, and carrying large dimension circular or square plates. Both stainless steel spatulas and Teflon coated spatulas are provided.
The spatula-type attachments are appropriate for the handling of silicon wafers, CDs and glass plates.
