Technical Specification
Our high-performance Rubber Support Inserts are precision-engineered for chilled water and HVAC piping systems. Made from high-density EPDM or Neoprene rubber, these inserts provide superior thermal insulation, vibration control, and load-bearing support. They maintain insulation continuity, eliminate condensation, and ensure energy-efficient operation.
- Material: EPDM / Neoprene Rubber
- Density: 200 – 600 kg/m³
- Temperature Range: -35°C to +120°C
- Compressive Strength: 0.5 – 1.5 N/mm²
- Pipe Size Range: DN15 to DN600 (½” to 24”)
- Fire Rating: BS 476 Part 7 Class 1 (optional)
- Finish Options: Galvanized / Stainless Steel Clamp or Saddle
Key Features and Benefits
- Acts as a thermal break to prevent condensation and thermal bridging at pipe supports.
- Reduces vibration and structure-borne noise in HVAC systems.
- Supports heavy pipes with minimal deformation for long-term performance.
- Manufactured from durable EPDM or Neoprene rubber resistant to UV and temperature extremes.
- Prevents corrosion under insulation (CUI) by eliminating moisture buildup.
- Ensures seamless insulation continuity and vapor barrier integrity.
- Quick and easy installation with minimal maintenance required.
Industries and Applications
- HVAC and Building Services – chilled and condenser water systems.
- Commercial Buildings – offices, hospitals, malls, and hotels.
- Industrial Facilities – process cooling and utility piping.
- Data Centers – high-efficiency chilled water systems.
- Pharmaceutical & Clean Rooms – moisture-controlled environments.
- Infrastructure Projects – airports, metros, and campuses.

Installation Guidelines
- Ensure the rubber insert thickness matches the insulation thickness.
- Place the insert between the pipe and support clamp before tightening.
- Seal insulation joints and vapor barrier properly to prevent condensation.
- Use bonded metal saddles for heavy-duty or large-diameter pipes.
Quality Assurance and Compliance
- Manufactured under ISO 9001 certified quality systems.
- Complies with ASHRAE and SMACNA guidelines for insulated supports.
- Fire-rated and RoHS compliant materials available.
- Tested to international ASTM standards for mechanical performance.
Key Features & Benefits
- Thermal Break – Prevents condensation and thermal bridging at support points.
- Durable Material – Made from high-density EPDM or Neoprene rubber for long life.
- Load Bearing Strength – Withstands heavy pipe loads without deformation.
- Vibration & Noise Control – Minimizes structure-borne noise and vibration.
- Condensation Protection – Prevents “sweating” and corrosion under insulation (CUI).
- Easy Installation – Fits standard pipe clamp and hanger systems.
- Insulation Continuity – Matches thickness of pipe insulation for complete vapor barrier integrity.
