Inflatable Seals

High-Lift Inflatable Rubber Seals Technology

When precision seals are a must

Nufox are a specialist inflatable seals manufacturer, with extensive experience in specification and production of seals for a wide range of applications.

When do you need inflatable seals?

We have developed a range of high lift inflatable seals for use when good sealing is required, for example:

  • noise ingress
  • dust or dirt ingress
  • moisture ingress, or
  • fume ingress are an issue, and cannot be tolerated.

This may also be where a high closing force is not available.

The high lift type is appropriate where sealing of a large gap is of prime importance. Our inflatable seals are manufactured to the deflated shape. Upon the application of air pressure, typically 0.3 to 0.6 bars they can expand and force the rubber bead against a mating surface to provide a secure seal.

How does it work?

Upon release of the pressure the diaphragm and bead return to the deflated condition relatively quickly and without the need to resort to vacuum application. The seal may be secured mechanically in a channel or bonded with a suitable bonding agent. Inflatable seals are typically produced as loops, which can be formed around various shapes allowing for radiused corners with minimum bends determined by profile size.

The seal will not function against an angled joint. Fixing lugs may be designed in conjunction with customers’ requirements.

What are inflatable seals used for?

Some examples of seals in action include:

• Door seals on underground trains to keep noise levels to an acceptable level.
• Platform seals on vessels at sea to prevent water and weather ingress.
• Seals on filters inspection panels for the dust extraction industry.

Inlet ports can be designed to suit customer requirements and connections are either standard Schrader valves or specifically designed ports are available.

Industries that use inflatable seals include:

  • Transport
  • Shipping
  • Manufacturing
  • Nuclear
  • Commercial
  • Processing
  • Marine, and more.

Frequently Asked Questions

How does the process work?

We can take your concept through design, sampling, to finished product in-house, with complete control throughout. We have a number of processing options, and our total in-house control of design, manufacturing and tooling ensures that we can maintain timelines and achieve your delivery expectations.

Are your products bespoke?

Yes, at Nufox we provide you with a product that is totally compatible to your design and functional requirements.

Are there minimum order quantities?

No, but many of our products require tooling development, processing machine set up and compound selection. So the costs involved in this process have to be allocated to the project. But if a small quantity is required for fit and function, this can be accommodated.

What are the lead times for a product.

If the product is a new development requiring tooling, this can often be less than four weeks. However if the project is complex and requires a specially formulated compound, this can be longer. Once we have your enquiry, we are able to give you an indicative production time.
