Inflatable Seals

Inflatable Seals

Non-Reinforced Inflatable Seals in the USA

Inflatable seals can be used for a variety of applications where sealing two surfaces that move in relationship to each other is required. A rubber seal will begin to expand at a specified rate until a determined size of expansion is achieved simply by using air or fluid as a medium. The size and rate of expansion for an inflatable seal are predetermined by its shape and available sizes. For unique or custom applications, we can engineer custom inflatable seal solutions for your application.

Nearly all our inflatable seals in the USA are custom fabricated for a specified application, and we can use many of our standard profiles to develop an inflatable seal to a custom required working parameter. Both money and time can be considerably saved when you use our standard profile.

Note: Additional tooling may be required to create a square or rounded corner in some cases. It may also be required to run a certain type of compound. Extrusion runs may require extra time for development.

Fabric Reinforced vs. Homogenous Inflatable Seals

In addition to homogenous (all rubber) seals, as one of the best inflatable seals manufacturer in the USA, we offer fabric reinforced seals. These seals have a layer of fabric embedded into the walls of the seal. The fabric layer allows a seal to handle much greater pressure.

  • Homogenous Seal Pressure – up to 25psi
  • Fabric Reinforced Seal Pressure – up to 90psi

Fabric reinforcement has several benefits with an understandable trade-off – cost. Fabric-reinforced seals are much more difficult to produce and must be molded during a handmade process. However, the benefits of reinforced seals are quite specific:

Homogeneous Seals Fabric Reinforced Seals
Greater flexibility Longer life
More economical Greater seal resilience
Faster to produce Higher operating pressures
Improved tear resistance

There is one notable exception about Homogenous seals and high operating pressures – a well-designed homogenous or fabric-reinforced seal with a fully contained retainer will allow for extremely high operating pressures beyond 65psi.

FAQs

  1. What are the key factors in choosing inflatable rubber seals?Some of the key factors for selecting inflatable rubber seals are operating environment, pressure requirements, and temperature range. Moreover, the material compatibility and application specifics.
  2. Can inflatable seals create an air-tight seal?Yes, absolutely. Our custom inflatable seals are designed to provide a proper air-tight seal. These exert uniform pressure on the surface, which helps create a complete barrier in the air passage.
  3. How long does an inflatable seal last once it is used in something?It is dependent on the application. Some parts are replaced every few months while others can last for years. Main factors are environment, cycles, pressures and wear on the rubber.
  4. Can I use inflatable seals for large gaps?Inflatable seals in the USA can be used for large gaps, but the size and design of the seal need to be carefully selected to ensure effective sealing.
  5. How do I get a quote for the seals?Well, getting a quote from us is pretty easy. You will just have to fill out our form with all your information. After that, someone from our team will just reach out to you.
  6. Do you have any certification for your inflatable seals in the USA?We are ISO9001 -2015 certified. We also offer FDA certs, certificates of conformance, materials and testing.
