Square Silicone rubber cord is a Silicone sealing profile with a square cross-section, designed for gap sealing, dimensional compensation, vibration reduction, and elastic cushioning between two mating surfaces.

It is suitable for machinery, industrial equipment, cabinet doors, machine covers, flanges, and applications requiring a flexible material with good heat resistance.

The product can be manufactured in various cross-sectional sizes, from small profiles for narrow gaps to larger profiles for applications requiring greater gap compensation.

Common Square Silicone Cord Sizes

Commonly searched and used sizes include:

REP Vietnam can also manufacture square Silicone rubber cord according to custom dimensions, physical samples, or technical drawings.

Note: The gasket size should always be checked against the actual groove and installation gap. Do not select a profile based only on its nominal size without checking compression requirements.

Advantages of Square Silicone Rubber Cord

The square cross-section provides a relatively stable contact area when installed inside a groove or compressed between two surfaces.

Key characteristics include:

• Good elasticity.
• Good recovery after compression.
• Good heat resistance depending on Silicone grade.
• Aging resistance.
• Ozone and UV resistance.
• Stable deformation characteristics under suitable operating conditions.
• Effective gap compensation when correctly compressed.
• Available in various cross-sectional sizes.
• Continuous production or custom cutting.

For high-temperature applications, the continuous operating temperature and maximum temperature should be specified to select the appropriate Silicone compound.

Gap Compensation and Sealing Performance

In practical assemblies, mating surfaces often have dimensional variations. Silicone rubber can deform under compression and create contact between the two surfaces.

With the correct profile and compression level, the gasket can help:

• Seal gaps.
• Reduce dust ingress.
• Limit water and moisture penetration.
• Compensate for minor dimensional variations.
• Reduce vibration.
• Reduce impact.
• Protect contacting surfaces.

A thicker gasket does not automatically provide better sealing. An oversized profile can increase compression force and make doors or covers difficult to close. An undersized profile may not generate sufficient contact pressure.

How to Select the Correct Square Silicone Size

The best approach is to measure the actual installation location.

1. Measure the Groove

Use a caliper to measure groove width and depth. For uneven grooves, measure multiple locations to determine the minimum and maximum dimensions.

2. Measure the Closing Gap

For doors, covers, and cabinets, measure the distance between the two mating surfaces when fully closed.

3. Determine Compression

The gasket should be compressed enough to generate sealing pressure without excessive deformation.

Oversized gasket: difficult closing, excessive compression and deformation.

Undersized gasket: insufficient contact pressure and possible leakage gaps.

4. Confirm the Cross-Section

For example, a 5x5 mm square Silicone cord has different compression characteristics from 10x10 mm or 15x15 mm profiles. Substitution should be based on actual groove and installation dimensions.

Applications of Square Silicone Rubber Cord

Typical applications include:

• Machine cabinet doors.
• Electrical cabinets.
• Machine covers.
• Equipment housings.
• Flanges.
• Industrial machinery.
• Heating equipment.
• Technical enclosures.
• Doors and frames.
• General sealing and cushioning applications.

For applications involving oils, fuels, or specific chemicals, Silicone compatibility should be evaluated before material selection.

Custom Square Silicone Cord Manufacturing

REP Vietnam can manufacture square Silicone rubber cord according to:

• Custom dimensions.
• Physical samples.
• Technical drawings.
• Required hardness.
• Custom colors.
• Required lengths.
• Dimensional tolerances.
• Small quantities.
• Large production volumes.

Typical process:

Sample/Drawing → Dimension confirmation → Silicone selection → Production → Profile inspection → Cutting → Packaging.

For OEM orders, it is recommended to confirm the cross-sectional dimensions, hardness, tolerances, and operating conditions before production to maintain consistency between batches.

Square Silicone Cord Pricing

Pricing depends on:

• Cross-sectional dimensions.
• Silicone grade.
• Hardness.
• Color.
• Length.
• Order quantity.
• Dimensional tolerances.
• Processing requirements.

For an accurate quotation, please provide the profile size, required length, quantity, and operating environment.

If the correct size is unknown, customers can provide an existing gasket sample or installation photo together with groove dimensions. This is often more reliable than selecting a size by product name alone.
