Inflatable Seals: customised solutions for every industrial application

We make industrial inflatable seals in silicone, EPDM and other polymers for every industrial application. They solve sealing issues where static seals are inefficient, becoming active components within systems.

Why choose inflatable seals?

When dealing with sealing issues between moving parts, or with varying clearances, New Rubber inflatable seals are the most effective solution for this type of condition, as they:

  • ✓ expand only when necessary (axially or radially)
  • ✓ seal any opening with even pressure
  • ✓ offer advantages such as easy assembly/disassembly
  • ✓ conform to complex surfaces

Further solutions: they can be used to clamp, move or brake components, such as in packaging lines, or as a dynamic component to effect movement, replacing actuators or air pistons.

FAQ

Unlike static seals, New Rubber inflatable seals allow the sealing of surfaces with large tolerances or between moving parts. They ensure zero friction during opening/closing or movement and an even seal around the entire perimeter, reducing mechanical wear and maintenance time.

We make seals from Silicone, widely used in the food and pharmaceutical sectors, as well as EPDM, NBR and Neoprene. Our compounds are FDA, FCMA (Reg. 1935:2004) and USP Class VI certified, in compliance with the specific standards required for the food and pharmaceutical industries. We always guarantee full compliance with the strictest industry standards.

Inflatable profiles can be used to make actual dynamic components for holding and handling products, or they can replace actuators, clamps or braking systems for moving, slowing down or locking products.

The inflation pressure varies depending on the material, profile geometry and clearance to be filled. By testing on our dedicated test bench, we can help set the optimum parameters for each specific industrial application.

Three modes of expansion:

  • radially out (RGE)
  • radially in (RGI)
  • axially (RGA)

To guarantee effective expansion and retraction of the seal, it is essential to comply with specific minimum bending radius measurements, which vary according to the type of profile and mode of expansion.

Each inflatable seal is individually tested at our laboratory in order to pass our quality controls. We test pressure expansion and hermetic seal, ensuring that every part shipped meets the stringent reliability standards required by the various sectors of application.
