Rubber sleeve

A rubber sleeve is a durable, flexible connection between machine parts or installation parts. It is used, amongst others, in air treatment installations and air ducts. A sleeve protects against dust, dirt and moisture. Ridderflex produces custom-made sleeves for you.

Properties of a rubber sleeve

The rubber sleeve is used between machine parts or installation parts. Use of a sleeve:

  • reduces the risk of damage to pipes and possible material fatigue;
  • reduces the transmission of noise and vibrations and
  • protects against dust, dirt and moisture.

Different types

We supply the rubber sleeve amongst others in the following types:

Straight sleeveUsed as a dust cover for protection of machine parts and as a connection sleeve in air ducts.
Conical sleeveUsed, amongst others, for connecting pipes or for the transition of a round to a rectangular cross-section.
