The T-shaped silicone seal is designed with:

  • Stem (leg): securely fitted into the groove
  • Head (top): creates the sealing contact surface

This structure provides:

  • Stable installation
  • Even pressure distribution
  • Reduced displacement during operation

At REP Vietnam, we manufacture blue T-shaped silicone seals on demand, suitable for:

  • Brand identity (custom color matching)
  • Food industry standards (easy contamination detection)
  • Hygienic and controlled environments

Silicone Material Properties – The Foundation of Performance

 Heat Resistance

Silicone operates effectively within a wide temperature range:

  • From -60°C to 250°C
  • Maintains elasticity under extreme conditions
  • Resistant to thermal aging

Typical applications:

  • Oven doors, drying chambers
  • Industrial heating systems
  • Sterilization and autoclave equipment

Chemical Resistance & Biocompatibility

  • Non-reactive with food-grade substances
  • Odorless, non-toxic
  • Can meet FDA standards (depending on grade)

Ideal for:

  • Food & beverage processing
  • Pharmaceutical and medical equipment
  • Cleanroom environments

Shore A Hardness – The “Core” of Sealing Performance

Shore A hardness (30–80) directly affects:

  • Elasticity
  • Compression sealing ability
  • Mechanical durability

30 – 40 Shore A (Soft)

  • High flexibility, conforms to uneven surfaces
  • Excellent sealing under low pressure

Suitable for:

  • Medical devices
  • Food processing equipment requiring tight sealing

Limitation: lower tear resistance under high mechanical stress

50 – 60 Shore A (Most Common)

  • Balanced flexibility and strength
  • Stable sealing performance

Applications:

  • Industrial machinery
  • Thermal chamber doors
  • Air and fluid sealing systems

70 – 80 Shore A (Hard)

  • High strength, low deformation
  • Suitable for high-pressure environments

Applications:

  • Pressurized chambers
  • Heavy-duty machinery

Warning: excessive hardness reduces sealing efficiency due to poor surface conformity

Commonly Requested Dimensions for T-Shaped Silicone Seals

Based on market demand, the following are typical specifications:

1. Stem Width (Groove Fit)

  • 3mm – 5mm (small equipment, food machinery)
  • 6mm – 8mm (medium industrial systems)
  • 10mm – 15mm (large ovens, chambers)

2. Head Width

  • 8mm – 12mm (light-duty sealing)
  • 15mm – 20mm (standard industrial use)
  • 25mm – 40mm (large thermal doors)

3. Sealing Thickness

  • 2mm – 4mm (low pressure)
  • 5mm – 8mm (general applications)
  • 10mm – 15mm (high-pressure sealing)

4. Length Options

  • Cut-to-length
  • Continuous rolls
  • Vulcanized endless joints

Important note:
A deviation of just 0.5–1mm can reduce sealing efficiency by up to 30–50% in high-temperature or high-pressure systems.

Why Custom Manufacturing Is Essential

Standard off-the-shelf seals often result in:

  • Improper groove fit
  • Incorrect hardness
  • Reduced lifespan

Custom production ensures:

  • Optimal sealing performance
  • Lower operating costs
  • Extended equipment lifespan
