Square Rubber Gasket
Square rubber gaskets are flat sealing components designed with a square or rectangular profile, commonly used where straight-edge sealing and uniform surface contact are required. Compared with round gaskets, square rubber gaskets provide better coverage for rectangular flanges, frames, and housings.
Manufactured from high-quality elastomer materials, square rubber gaskets deliver reliable sealing performance against liquids, air, dust, and chemicals while maintaining dimensional stability under compression.
Key Features
- Square or rectangular profile for straight-edge sealing surfaces
- Uniform compression and stable sealing performance
- Excellent resistance to aging, temperature, and chemicals
- Available in various thicknesses and hardness options
- Easy installation and replacement
Design Advantage: Square rubber gaskets are ideal for applications where round gaskets cannot provide full surface coverage, ensuring improved sealing integrity on rectangular interfaces.
Material Options
Square rubber gaskets can be produced using a wide range of elastomer materials to match different operating conditions:
- EPDM: Excellent resistance to water, steam, and weathering
- NBR: Good oil and fuel resistance
- Silicone (VMQ): Wide temperature range and food-grade availability
- FKM (Viton®): Superior chemical and high-temperature resistance
- Neoprene (CR): Balanced mechanical strength and aging resistance
Material Selection Tip: Selecting the correct rubber compound is critical to ensure long-term sealing performance and compatibility with the working media.
Manufacturing Methods
- Die Cutting: Cost-effective solution for high-volume flat gaskets
- Compression Molding: Suitable for thicker or complex profiles
- CNC / Lathe Cutting: High precision for custom and low-volume orders
Applications
- Rectangular flanges and covers
- Electrical enclosures and cabinets
- HVAC systems and air handling units
- Industrial machinery and equipment housings
- Water treatment and filtration systems
