What is a Rubber Strip？
Rubber strips play a crucial role in sealing applications across the commercial and industrial sectors. Rubber strips, often called rubber seal strips, rubber seals, weather striping, or rubber gaskets, are fundamental components in countless industrial applications. Rubber sealing strips come in various materials and shapes to suit many purposes. EPDM rubber remains a popular choice due to its well-rounded properties of flexibility, durability, and weather resistance. Their function is vital, preventing leaks, drafts, dust, and other unwanted elements from compromising a system's integrity or performance. Zhongxiang Rubber is a professional custom rubber seal strip manufacturer that offers various types of rubber seal strips, including waterproof rubber seal strips, automotive rubber seal strips, Round Rubber Seal Strips, flat rubber seal strips, adhesive rubber seal strips, rubber seal strips for doors, and rubber seal strips for windows. We can provide custom rubber strips, rubber seals, and rubber gasket solutions based on customer-specific requirements(drawings or samples).
Type of rubber seal strips
They are mainly classified according to their material and cross-sectional shape. Below is an overview of some of the most common types:
| Materials | Key Properties & Resistance | Common Applications |
| EPDM (Ethylene Propylene Diene Monomer) | Excellent resistance to weathering, UV rays, ozone, and water. Wide temperature range. Not oil-resistant. | Outdoor use, automotive weatherstripping (doors, windows, trunks), HVAC systems, water-system gaskets. |
| Silicone (VMQ) | Excellent high and low-temperature resistance, flexibility, and good resistance to UV/ozone. Can be food-grade. | Aerospace, electronics, ovens, medical equipment, food-grade pumps, and extreme weather conditions. |
| Neoprene (CR) (Polychloroprene) | Good all-around balance: moderate resistance to oils, chemicals, and weathering. Durable and versatile. | General-purpose industrial seals, marine applications, cable jackets, refrigeration seals. |
| Natural Rubber (NR) | High elasticity, flexibility, excellent tear resistance, and high tensile strength. Poor UV resistance. | General sealing, cushioning, and shock absorbers where weather/chemical resistance is not critical. |
| Nitrile (NBR) (Nitrile Butadiene Rubber) | Excellent resistance to oils, fuels, and hydraulic fluids. Good abrasion resistance. | Automotive engines, oil and gas applications, industrial seals, and environments exposed to oils/greases. |
| Viton (FKM) (Fluoroelastomer) | Exceptional high-temperature and chemical resistance, very good resistance to oils and fuels. | Aerospace, chemical processing, high-performance automotive, and demanding industrial environments. |
Types by Seal Strips Shape (Cross-Sectional Profile)
The rubber seal shape is designed to fit specific grooves or gaps to create a tight seal.
| Shape | Description | Common Use |
| D-Shape | Resembles the letter 'D'. Flat side adheres to the surface, and the curved side compresses to form a seal. | Doors, hatches, and enclosures to seal against air, water, and dust. |
| P-Shape | Resembles the letter 'P'. Used to seal a gap while the "tail" or flat part is attached to the surface. | Weatherstripping, especially for doors and windows. |
| U-Channel | U-shaped cross-section that fits over and grips an edge. | Edge protection, covering sharp metal or glass edges, and simple channel sealing. |
| O-Ring | A round, torus-shaped cross-section. Simple yet highly effective when compressed in a groove. | Static and dynamic applications like hydraulic systems, engines, pumps, and valves. |
| Square/Rectangle (Flat Gaskets/Strips) | Solid or sponge material cut into a simple flat profile. | Sealing flat surfaces, cushioning, and simple gasket applications in machinery. |
We can also provide rubber seals with two internal structures: solid rubber and sponge rubber.
Solid Rubber: A dense, non-porous material offering high durability and better resistance to abrasion, impact, and wear.
Solid rubber: A dense, non-porous material with high durability and better resistance to wear, impact, and aging.
Adhesive Rubber Strips
There are also adhesive-backed options. The biggest advantage of adhesive-backed sealing strips is their quick and easy installation. They usually have a layer of 3M adhesive or other high-adhesion adhesive on the back; simply peel off the release paper and stick them on without any additional glue or fasteners. They are widely used for sound insulation, windproofing, dustproofing, and waterproofing in both residential and industrial environments.

How to install a sealing strip and gaskets?
Clean the surface to ensure the area will be applying the seal strip is clean, dry, and free of dust.
Measure the length of the area you need to seal.
Cut the seal strip (if necessary)
Peel back the backing (partially) and position the seal strip
Press the strip firmly onto the surface for a secure bond.
Regularly check the strip rubber and replace it if needed.
