Frequently Asked Questions

  • Are “vacuum insulated” and “vacuum jacketed” the same thing?

    Yes, the terms “vacuum insulated” and “vacuum jacketed” are used interchangeably.

  • Are bulk discounts available?

    Yes, bulk discounts are available for qualifying orders. Request a quote →

  • Are end fittings already attached?
    • CGA295 (JIC Swivel Nut) end fittings will be delivered attached to the hoses.
    • Compression fittings will be delivered unattached.
  • Are high pressure vacuum jacketed hoses available?

    Yes, high pressure Insulon vacuum jacketed hoses are available. Contact us to request a quote →

  • Are Insulon parts DFARS compliant?

    Yes, Insulon parts can be manufactured to be DFARS compliant.

  • Are Insulon Safety Guards removable?

    No, Insulon Safety Guards are not removable. The retrofit is designed to be permanent. Do not remove and reattach the safety guard to the heat gun.

  • Are other end fittings available?

    Yes, we can supply virtually any end fittings that you need for your hose assembly. Our standard end configurations include CGA-295 end fittings and compression fittings, and these are typically available with the shortest lead times.

  • Can components be welded onto Insulon parts?

    It is possible for components to be welded onto Insulon parts, depending on the application. If your application requires a flange or mounting bracket, let us know and we can supply it as a completed assembly.

  • Can I hold onto the Insulon Safety Guard while I’m working?

    Insulon Safety Guards are not designed to be tool-holding surfaces. They are designed to reduce the risk of burn injury, and in the event of a burn, to reduce the severity of the burn. Heat gun operators should always follow best practices for heat gun safety. Do not hold on to the heat gun by the Safety Guard.

  • Can vacuum insulation be used in food-grade applications?

    Yes, advanced vacuum insulation can be engineered to meet food-grade insulation requirements including food-grade pipe insulation. Some of the benefits of advanced vacuum insulation for food-grade applications include non-fibrous materials, easy-to-clean surfaces, and reduced risk of corrosion under insulation (CUI).

  • Can vacuum insulation be used in medical-grade applications?

    Yes, advanced vacuum insulation can be designed for medical and surgical applications such as thermal ablation therapies. Manufactured from stainless steel, Insulon parts are easily sterilized.

  • Can vacuum jacketed hoses be ordered in longer sections and cut to length?

    No, vacuum jacketed hoses cannot be cut to length after delivery. They must be ordered in the correct size.

  • Does Concept Group manufacture high volumes?

    Yes, Concept Group uses state of the art automation technology to manufacture millions of parts per year with high precision and rigorous quality control.

  • Does Concept Group ship internationally?

    Yes, Concept Group has many international business relationships. We look forward to working with you regardless of your location.

  • How is vacuum insulation made?

    We engineer and manufacture Insulon vacuum insulation according to Concept Group’s proven Core Process. Learn more about engineering vacuum insulation.

  • How long does vacuum insulation last?

    When designing Insulon parts, our engineers carefully consider the longevity requirements of your application including duration of use, thermal cycling, exposure to thermal shock, and performance requirements. We focus on life cycle optimization to ensure the greatest ROI for your company.

  • How long has Concept Group LLC been in business?

    Founded in 1970, Concept Group LLC (formerly Concept Group Inc.) has been in business for over 50 years.

  • Is advanced vacuum insulation available in pipes, tubes, or flexible hoses?

    Yes, Insulon vacuum insulation is available in rigid pipes, flexible hoses, and bend-to-shape tubing. Insulon is engineered in diameters ranging from millimeters to 12 inches.

  • Is Concept Group a Steinel distributor?

    Yes, Concept Group is a proud distributor of Steinel products. Contact us to request a quote.

  • Is Insulon® a thermal barrier coating (TBC)?

    No, Insulon® is not a thermal barrier coating. Insulon® is a double-walled vacuum insulation technology that is manufactured as standalone components including tubes, pipes, cans, containers, flasks, cones, and custom geometries. And while not a coating, the overall wall thickness of ­­Insulon® parts can be as thin as 0.25 mm.

  • Should I remove the nozzle from my heat gun?

    No, you should not remove the nozzle. Insulon Safety Guards are not intended to replace the heat gun nozzle; they are intended to go around the nozzle.

  • What are R-values and U-values?

    R-values are used to measure an insulation material’s thermal resistance. Insulation materials with higher R-values can reduce heat transfer more effectively. U-values are used to measure thermal transmittance. Insulation systems with lower U-values have a lower rate of thermal transmittance than those with a higher U-value.

  • What does LP stand for?

    LP stands for low pressure. Insulon Hose LP is our line of vacuum jacketed hoses for low pressure applications.

  • What insulation materials are used to make vacuum jacketed products?

    We manufacture Insulon vacuum insulation with stainless steel, Inconel, and other alloys. Materials are selected according to the requirements of each application and can be selected to fulfill applicable standards and guidelines, including:

  • What is Insulon® Technology?

    Insulon® is a patented advanced vacuum insulation technology that is used to create high-performance thermal insulators. Effective in both cryogenic and high-temperature applications, Insulon® can operate in thermal environments ranging from -270°C to 1000°C. Our most advanced parts include proprietary high-temperature multi-layer insulation (MLI) installed inside the vacuum annulus for vacuum super insulation performance.

  • What is the R-value for Insulon?

    Our engineers custom design Insulon vacuum insulation to excel in individual applications according to the parameters of each unique system. This means that the thermal resistance, or R-value, varies with each part. Many Insulon thermal barriers have an overall wall thickness in the order of millimeters and can deliver hundreds of degrees of temperature difference.

  • Where are Concept Group’s products designed and manufactured?

    Concept Group’s products, including Insulon® parts and our glass to metal seals, are designed and manufactured in the United States.

  • Will the Insulon Safety Guard fit on my heat gun?

    Insulon Safety Guards are currently available for Steinel HG 2320 E and Milwaukee 8975-6 heat guns. To request a custom Safety Guard for another hot air tool, please use this form. Custom jobs are evaluated on a case-by-case basis.
