The Best Rubber Support Insert Manufacturer in Saudi Arabia
The purpose of rubber support inserts is to keep low-density pipe insulation from being crushed at hanger locations. When pipe insulation runs through a clevis hanger, roller, anchor, guide, or strut system, appropriate pipe insulation supports and shields are essential for preserving thermal performance and system integrity. Heat or moisture cannot be directly transferred from the shield to the pipe thanks to these supports. At Diode Trading EST, we provide the best rubber support insert in Saudi Arabia to help you with your project.

Rubber Support Insert for Chilled Water & HVAC Pipes – FAQs
Q1. Where are rubber support inserts commonly used?
A. Rubber support inserts are used in automotive, electronics, and general construction for cushioning and isolation. Still, they are mainly used in HVAC and piping systems to prevent insulation crushing at supports, maintain thermal performance, and dampen vibration.
Q2. Are rubber support inserts suitable for chilled water systems?
A. To ensure thermal performance, prevent insulation from being crushed at support points, and reduce vibration and noise in HVAC and piping systems, rubber support inserts are highly appropriate. They are frequently used in chilled water systems.
Q3. How long do rubber support inserts last?
A. Rubber support inserts usually have a lifespan of 3 to 12 months in over-the-counter insoles. However, custom-made orthotics can last several years. The lifespan of support inserts can vary greatly.
