Square Rubber Grommet
Square Rubber Grommet
Square rubber grommets are specialized hardware components designed to fit square or rectangular panel cutouts, providing critical insulation, sealing, and protection for cables, wires, or tubes.
Overcoming Engineering Challenges in Square & Rectangular Sealing
Unlike standard round grommets, square rubber grommets face unique mechanical stress, especially at the 90° sharp corners or tight radius edges (R-corners).
- Stress Concentration: Sharp corners are highly susceptible to tearing and material thinning during the compression molding process.
- Sealing Performance: Achieving an airtight or IP67-rated waterproof seal on sheet metal or plastic enclosures with straight edges requires precise tolerance control and optimized hardness (Durometer).
At Flexiparts, we don’t just replicate your design; our engineering team conducts a thorough DFM (Design for Manufacturability) review. We analyze the parting lines, flash thickness, and corner radius of your custom square grommet blueprints to ensure optimal elastomeric performance and defect-free production.
Common Material of Square Grommet Rubber
- EPDM
- NBR
- CR
- MVQ
- NR
- FKM
Why Use Square Rubber Grommets Instead of Round Ones?
- Better fit for square openings
- Prevents rotation
- Improves panel stability
- Better cable organization
- Larger contact surface
