Airfit K13322 DN 110 HT Screw-on Sleeve, Grey Plastic

A DN 110 HT screw-on sleeve makes it possible to connect a pipe through a container, plate or machine cladding. Its internal mount is designed for a 110 mm HT pipe, giving the connection a defined size to work with. The grey plastic fitting is resistant to household wastewater and hot water up to 90 °C. It suits projects where a connection through a surface is needed, rather than a fitting intended simply to join pipe lengths.

How to use it

Use the sleeve as a pipe connection through a suitable panel, container or machine cladding. Plan the opening around the required 121 mm bore diameter, then match the fitting to a 110 mm HT pipe and the surface thickness. It is designed for wall thicknesses from 1 mm to 17 mm, so these measurements help establish whether the installation matches the fitting before work begins.

For example, when a 110 mm HT pipe needs to pass through a plate or container wall, this sleeve provides the specified connection format for that task. A conventional inline pipe fitting serves a different purpose: it is intended for connecting pipe runs, while this screw-on sleeve is aimed at a connection through a surface. The choice depends on where the pipe needs to meet the surrounding structure.

Pros

The DN 110 size and 110 mm internal pipe mount make the intended pipe connection clear. This helps when selecting a fitting for a project with a specified HT pipe diameter, rather than relying on a general-purpose connector. The required bore diameter and suitable wall-thickness range also give practical dimensions to use when planning the opening and fitting location.

Material resistance is useful in everyday drainage settings. The sleeve is resistant to household wastewater, and its stated hot-water resistance is up to 90 °C. That makes it relevant to applications where the connected pipe may carry household wastewater at elevated temperatures, within the stated temperature range. Its grey finish provides a neutral appearance alongside the installation.

Final verdict

For a project that needs a 110 mm HT pipe connection through a container, plate or machine cladding, the Airfit K13322 brings the relevant fit and installation dimensions together in one sleeve. Its stated wastewater resistance and hot-water limit make it particularly suited to household drainage applications, while the 121 mm bore requirement and 1 mm to 17 mm wall range help guide the choice of fitting for the surface involved.
