All information on our website is without guarantee.
In the interest of technical progress, we reserve the right to make changes and improvements without notice.

When manufacturing our products, we comply with the applicable standards with regard to geometric dimensions, tolerances and quality requirements.

For pipeline systems in gas supply, for example, DIN EN 1555 is decisive. In the water supply, as well as for drainage and sewage pressure pipes, the DIN EN 12201.

If you require certain tolerances, please contact us.

We would be happy to send you a customer drawing with approval.
