A critical component in cryogenic containment vessels, dewars, are the corks and plugs utilized in these insulated containers. Dewar corks and plugs are commonly constructed of foam materials and are used for the temporary storage of cryogens. Customized foam corks and foam plugs are necessary to efficiently and safely contain these ultracold materials.
At PFI, we manufacture over 50% of all cryogenic plugs and corks used in the United States. We are industry-leading cryogenics manufacturers for dewar plug and cork fabrication. For a custom foam cork fabrication, contact us to speak with our machined foam experts.
Cryogenic Plugs and Corks Fabrication
Cryogenic, bioscience, pharmaceutical and medical parts industries are just some that rely on specialized foams to be fabricated to precise specifications to endure and insulate temperature-sensitive materials. For substances such as vaccines and biopsies, shipping and storing the cryo material in containers filled with liquid nitrogen refrigerant significantly preserves the specimen and prevents its degradation.
For companies who utilize these cryogenic services, a vital component in these containers is the neck plug. These cryogenic neck plugs, also known as corks, are critical to the function of dewars. Cryo neck plugs must be fabricated from a high quality foam that can maintain its high insulation qualities at -320 degrees Fahrenheit. Cryogenic plugs must also be machined to the exact specifications and dimensions of the container to protect both the contents within the Dewar and those handling the container.
Fabrication of cryogenic plugs and corks is a highly specified process that requires extreme precision in manufacturing. PFI offers that precision in their machining and fabrication of a cryogenic plug or cork to endure the increase in demand for cryogenic technologies.

Through our decades of experience and our team of cryogenic foam experts, we can reverse engineer and create the best custom cut replacement parts on the market today.
What Does Reverse Engineered Cork Mean?
Reverse engineering is the ability to dissemble and analyze an object to understand how it was manufactured in order to reproduce or replicate it. The reverse engineering process, regardless of the field of application, consists of three critical components:
- Information extraction, examination, and analysis from the object.
- Abstracting information into a conceptual model to guide design of a new object.
- Review, test, and evaluate the model to assess whether it is an effective reproduction of the original.
PFI’s reverse-engineering capabilities are utilized in manufacturing many other products aside from just cryogenic foam. PFI can reverse-engineer your replacement components to create precise, machined reproductions, such as custom aerospace machining, precision medical machining, and more. We focus on quality control to outperform competitors and give you a solution to your industrial equipment questions.
The Advantages of Cryogenic Corks
Using cryogenic foam corks and plugs present several key advantages to the user. PFI can fabricate and machine rigid foam with a precision to meet even the most critical tolerances. Our cryogenic foam that we utilize has a temperature tolerance that can range from -320 to 350 degrees Fahrenheit.
These particular foams offer impeccable thermal insulating qualities and can be utilized in a wide variety of applications including Dewars fabrication. In the instance of Dewars, our cryogenic neck tube corks are an essential component in preventing any accidental interaction with the contents of the Dewars.
What Material Is Used For Making Dewar Cork?
Several different types of foam are suitable for cryogenic applications. At PFI, we used the highest quality materials to fabricate our dewar cork. We use the following materials in our industry-leading custom cut corks and plugs:
- Expanded polystyrene (EPS)
- Duna (Corafoam®)
- Diab-H45 and Diab-HGX F600
PFI prides itself on its ability to machine some of the most highly advanced foam materials in the industry. We are one of a small elite group of cryogenic fabricators in the United States with the capability to machine all DUNA foam products and Corafoam® materials. Contact our foam cutting specialists to machine and fabricate a variety of cryogenic products out of these superior materials to form corks and plugs to your Dewar tanks and containers.
