Product Description

Product Details and Specifications

When your application demands uncompromising strength and resilience, our 21x25mm heavy-duty silicone tubing is the definitive solution. Fortified with a substantial 2mm wall, this tube is engineered to withstand mechanical stress, resist kinking and collapse under vacuum, and handle moderate pressures with confidence. It is the premier choice for critical industrial, automotive, and machinery applications where operational integrity is non-negotiable.

Core Advantages:

  • Superior Structural Integrity: The thick 2mm wall provides exceptional rigidity and shape retention, virtually eliminating the risk of kinking in tight bends or collapsing under light vacuum conditions.

  • Enhanced Pressure Capability: Designed to reliably handle higher working pressures than standard tubing, making it suitable for pressurized fluid transfer and pneumatic systems.

  • Exceptional Durability & Longevity: Offers superior resistance to abrasion, tearing, and physical impact, ensuring a longer service life in demanding or high-traffic environments.

  • Robust Yet Flexible: While built for strength, it retains the inherent flexibility of silicone, allowing for manageable installation while providing maximum protection and performance.

  • Certified for Purity & Safety: Crafted from 100% platinum-cured silicone and compliant with FDA and LFGB standards, it is perfectly safe for food, beverage, and pharmaceutical transfer where purity is essential.

CRITICAL Application Note:

  • This product is sold by the meter and is supplied in a continuous length.

  • Performance Advisory: This heavy-duty tube is optimized for durability, moderate pressure, and light vacuum applications. While flexible, it is less pliable than thinner-walled alternatives.

  • Selection Guide: This 2mm wall tube offers maximum durability and kink resistance. For a balance of flexibility and strength, consider our 1.5mm wall tubing. For applications requiring maximum flexibility in complex routing, our 1mm wall tubing is the ideal choice.
