Spacer tubes

Spacer tubes are manufactured from steel, stainless steel or brass. They are used predominantly in the electrical industry. As for all Seeberger products you will be able to purchase the spacer tubes in all dimensions and with all special tolerances. The principal dimensions, however, you will be able to learn from the table below:

Diameter Spacer tubes

0.197 in (5 mm)
0.197 in (5 mm)
0.236 in (6 mm)
0.236 in (6 mm)
0.315 in (8 mm)
0.394 in (10 mm)

0.098 in (2.5 mm)
0.118 in (3 mm)
0.138 in (3.5 mm)
0.157 in (4 mm)
0.197 in (5 mm)
0.236 in (6 mm) (See SN 60310 as well)

To SN 60310 the linear tolerance for spacer tubes of up to 1.969 Inch length is -0.008. Up to 2.953 Inch it is -0.012. These tolerances we have set as a standard. Spacer tubes of greater lengths will be manufactured with special tolerances, when so requested. Over and above the dimensions the SN 60310 provides for we are able to manufacture many more variants within short periods of delivery.


For Seeberger there are no special lengths. All lengths from 0.079-19.685 Inch (2-500 mm) are standard. The linear tolerance of the standard-spacer tubes corresponds to the DIN-mean – this keeps costs down more than tight tolerances do. Naturally the tolerances of the spacer tubes may be cut to size to comply with the requirements.

Outer diameter

The outer diameter may be specified, upon request even with minimum and maximum tolerances. However, standard tolerances are the most cost-effective solution.

Inner diameter

The inner diameter may be specified with minimum and maximum tolerances.

Wall thickness

We are able to realise almost any wall thickness.


We are able to supply almost any surface.
