What is Seal Strip?

Seal strips are usually created of elastomers and polymers via extrusion molding. They are available in hundreds of shapes to fulfill the needs of various industries and applications. There are multiple seal strip shapes available on the market. Let’s discuss them one by one.

Different Shapes of Seal Strip

• J-Shape Seal Strips

J shape seal strips are a specific form of rubber seal with a J-shaped cross-section. The seal is created by a J-shaped profile that compresses. When the door or window is closed, forming a tight seal that prevents air, water, and grime from entering the enclosed space. Various materials can be utilized to meet the specific requirements of multiple applications. Silicone rubber, for instance, can be used for applications requiring high-temperature resistance. While EPDM rubber can be used for applications requiring UV and ozone resistance. Additionally, J-shaped closure strips are available in various colors. It can enhance the application area’s aesthetics or improve visibility. This permits greater flexibility and customization when selecting the appropriate J-shaped seal strip for a sealing application.

• Oval-Shape Seal Strips

Oval shape seal strips are a special form of rubber closure with an oval shape. The oval cross-section of the seal compresses when the door or window is closed, producing a compact seal. It will prevent air, water, and dust from entering the enclosed space. The oval rubber seal consists of an oval-shaped rubber seal and gasket, an oval-shaped rubber section, and a profile. EPDM, silicone rubber, and other elastomers are the standard materials for this form of seal strip. 

• U- Shaped Seal Strips

U-shaped seal strips are a form of seal strip that resembles the letter “U” in cross-section. There are a variety of U-shaped seal strip materials, including;

• Silicone rubber
• U Channel Trim Gasket
• Rubber Seal
• U Shaped Seal 
• U Section
• U Shaped Silicone
• U Channel Weather Stripping
• U Gaskets 

• Bulb- Shaped Seal Strips

Bulb-shaped seal strips are a unique rubber seal that resembles a bulb. The seal is comprised of a hollow, bulb-shaped section that compresses when the door or window is closed, forming a compact seal that prevents air, water, and grime from entering the enclosed space. Bulb-Shaped Seal Strips, such as bulb windows rubber seals, door bulb seals, bulb weather stripping, shower bulb seals, etc. Doors and entrances are prevalent applications in the automotive and construction industries. Bulb-shaped seal strips are available in materials such as:

• Butyl rubber
• EPDM
• Neoprene
• Nitrile rubber
• Silicone

• T- Shaped Seal Strips

The purpose of T-shaped seal strips is to seal between two surfaces intersecting at a right angle. Commonly used to prevent air and water leakage in construction applications like windows and doors. Numerous materials are available for T-shaped seal strips. Including EPDM, Neoprene, Nitrile rubber, silicone, etc. T Seal, T Channel, T Section Rubber Strip, T Shaped Seal & Gaskets, T Shaped Rubber Gaskets, T Rubber Trim, and T Shaped Weather Stripping are examples of T shape seal strips.

• V-Shaped Seal Strips

This form of seal sheet has a cross-section in the shape of a V, making it ideal for sealing gaps in V-shaped structures. V shape weatherstripping is available as channel seals, section segments, rubber v-channel, v-seal, v-section, and v-shaped gaskets. When extruding v-shaped seal strips and gaskets, we use the highest quality rubber material, which offers superior sealing, performance, and value. V-shaped seal strip materials include silicone, EPDM, and neoprene.

• H Shaped Seal Strips

This form of seal strip has an H-shaped cross-section, which makes it ideal for sealing spaces between two parallel surfaces. H shape seal strips are available as H shape seals, channel seals, H Section Rubber Seal, H Rubber Channel Seal, and section strips. Silicone, neoprene, and EPDM are used to create H-shaped seal strips.

• P- Shaped Seal Strips

Similar to D-shaped seal strips but having a rounded upper edge. They are frequently employed in the automotive and construction industries to provide an airtight seal between two surfaces. Various materials are available for P-shaped seal strips. Including EPDM, natural rubber, neoprene, and silicone. P shape seal strips are also known as P-shaped seals and gaskets, P Strip channels, P Sections, P Shape Extrusion Gasket, and P Shape Extrusion Gasket.

• Seal Strip Shapes: E- Shaped Seal Strips

Rubber strips with an E-shaped profile are a specific form of extruded rubber seal. They are typically comprised of high-quality rubber materials. They are utilized in various applications requiring a strong and enduring seal. The rubber strip’s E-shaped profile allows it to fit securely into an aperture or channel, creating an effective seal. They can prevent air, water, dust, and other elements from entering or exiting a sealed area. In addition to providing a high level of compression, the E-shaped design enables the rubber strip to conform to rough surfaces and maintain a secure seal. 

Conclusion

When selecting a sealing strip shape, make sure to consider your needs and application environment. Whether in home decoration or industrial production, choosing the right sealing strip shape can bring better results and long-term reliability.
