The D shape seal strip, renowned as one of the most favored weather stripping options across various applications, boasts a distinctive structure. Typically, it features a half-moon bulb along with a flat bottom. The resilience of the half-moon bulb enables it to withstand high pressure, while the adhesive-infused flat bottom ensures secure and adhesive attachment. D shaped seal strips commonly utilize sponge rubber materials, providing superior sealing capabilities, especially under pressure.
Advantages:
Applications:
Commonly employed in mobile equipment cabins, machine enclosures, door edges, window seals, automotive seals, and hydraulic equipment.
E shaped seal strips usually resemble the small English letter ‘e’ at the cross-sectional area. Like D shape seal strips, the half-moon part of the E shape seal supports high compression. The flat bottom helps in attachment with the projected application surface. E shape seal strips usually come as extruded silicone rubber for a channel, section strips, and weatherstripping.
Advantages:
Applications:
Popular in food processing, automotive, high-voltage insulation, and cabinet door seals.
This seal shape usually includes H shape silicone rubber seals, H rubber channel seals, and H shape section rubber seals. This seal strip type is traditionally used for high-temperature resistance ranging from -65°F to +400 °F.
Advantages:
Applications:
H shape seal strips are prevalent in various applications such as rail, aerospace, and civil engineering. Besides, it is also widely used in food, dairy, and HVAC applications. Moreover, H shape seal strips are also used in sound and heat insulation.
This seal shape comes in different forms, such as a J-shaped strip with thin and thick walls, flat and curved. Like other shapes, J shape seal strips also have diversity in selecting and matching varied materials and colors.
Advantages:
Applications:
J shape seal strips are popular in industries where temperature, ozone, electricity, and fungus are concerned. Moreover, these seal strips provide great flexibility and are perfect for electric insulation. Other applications include automobile weather protection, ship container sealing, marine, and aerospace.
This type of seal shape has a solid oval shape at the cross-section. The typical materials for this type of seal strip are EPDM, silicone rubber, and other elastomers. These materials are highly versatile and provide excellent sealing capabilities. Because of its tangible properties, it can withstand high compression pressure. The typical hardness of this type of seal strip is from 20 shore A to 80 shore A. Shore is a unit of the hardness of a material.
Advantages:
Applications:
This type of seal strip is widely popular in chemical industries. Besides, oval shape seal strips are also prevalent in hydraulic systems, electrical cabinets, etc.
These seal shapes typically have a single and double half-moon structure at the top and a flat surface at the bottom. As the name implies, these seal strips look like single or double bulbs at the cross-section. Most industries aim to use these seal strip shapes for water and chemical resistance.
Advantages:
Applications:
The typical use of bulb seal strips is between the door and the wall, either on the hinge or strike side. These seal strips are also popular in chemical industries, water treatment, food processing, etc.
