Flanges, gaskets, sealing and fastening materials

Flanges and gaskets for pipework

For connections that are long-lasting and provide a reliable seal, Zantingh supplies a wide range of flanges, gaskets, and fastening materials. These components are used in heating installations, boiler houses, technical rooms, and pipework for greenhouse horticulture, industry, and utilities.

The range includes welding neck flanges, threaded flanges, blind flanges, and slip-on welding flanges. These allow you to securely connect pipes, valves, and installation components while ensuring they remain easily accessible. For sealing, we supply gasket sets and gasket rings in various versions, including Klinger, rubber, and graphite.

Complete assembly of flange connections

You can also rely on Zantingh for the fastening materials themselves. We supply bolts, nuts, washers, spring washers, and threaded rods in various sizes and specifications. This ensures you have all the materials at hand to assemble flange connections completely and correctly.

In pipework, fit, sealing, and ease of assembly are what matter most. A flange or gasket must be suitable for the specific application, temperature, pressure, and medium within the installation. That is why our advisors are happy to assist you in determining exactly what you need for new construction, maintenance, or replacement.

Quickly available from stock

We deliver many common flanges, gaskets, and fastening materials quickly from stock. This allows you to continue your work with components that fit the installation and are ready for immediate use on-site.
