Custom-made gaskets - versatile, precise, durable

Our custom-made gaskets offer reliable sealing solutions for a wide range of sectors and applications - from industry and trade to the private sector. At diconfa, we manufacture your gaskets precisely to size as yard goods, flange gaskets or sealing paper - individually cut to the exact shape and thickness required.

Below we present our sub-categories - each with its specific advantages and areas of application:

Rubber gasket

Rubber gaskets are universally applicable for sealing machines, doors, windows or technical systems. We manufacture them to size – with rubber materials such as EPDM, NBR or SBR – depending on temperature or chemical requirements.

Sealing tape

Sealing tapes can be flexibly cut and easily applied – ideal for gaps, joints or transitions. Our sealing tapes adhere firmly and provide long-lasting sealing against air, water or dust.

Gasket paper

With gasket paper you can create thin, formable gaskets for oil, water or steam applications. Perfect for use in pumps, filters, units or as a base layer in technical areas.

Gasket sheets

Gasket sheets custom-made to size allow precise lining of plates or surfaces – suitable e.g. for machine covers or filter housings. You receive the sheets flexibly cut and available by the meter.

Flat gasket

Our flat gaskets custom-made provide reliable sealing between flat surfaces – e.g. on containers, lids, pipe connections and technical housings. We process flat gasket materials precisely according to your requirements.

Flange gasket

Flange gaskets are cut to the millimeter for standard and special flanges. They seal effectively against media such as water, oil or gas – ideal for mechanical engineering, heating and plumbing.

Foam gasket

Foam gaskets custom-made offer flexible, pressure-elastic sealing solutions – e.g. for housings, transport or insulation purposes. They are lightweight, sealing and provide both vibration and noise damping.

Roof window gasket

Specially for window replacement: roof window gaskets custom-made ensure optimum sealing against rain, snow and drafts. Precisely fitting to the millimeter for common systems such as Velux and Roto.

At diconfa, you can easily configure any gasket online - cut to size and directly ex works, with precisely fitting yard goods and maximum manufacturing precision.
