Frequently Asked Questions

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

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

• CGA295 (JIC Swivel Nut) end fittings will be delivered attached to the hoses.
• Compression fittings will be delivered unattached.

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

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.

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.

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).

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.

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

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

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

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

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.

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

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.

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.

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.

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.

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:

• food grade or food safe requirements
• medical grade or surgical grade requirements
• cleanroom requirements

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.

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.

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

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.
