CSD RISE Duct Sealing System

The CSD RISE duct sealing system is an industry-leading multi-cable penetration solution engineered to protect cable ducts, building entries, and vessel bulkheads against high-pressure water, hazardous gas, and intense fire. Proven across utility, industrial, and marine sectors for over 25 years, the CSD RISE duct sealing system delivers reliable, long-term infrastructure protection where standard duct foams or inflatable bags fail.

Utilizing high-grade elastomeric RISE® filler sleeves and FIWA® silicone sealant, this system accommodates complex cable configurations, including heavy armored power cables, control wiring, and telecom lines within circular or rectangular duct profiles.

Why Choose the CSD RISE Duct Sealing System?

Unlike rigid block-type transit systems or traditional mineral wool packings, the CSD RISE duct sealing system features a lightweight, self-governing layout. This design prevents over-packing during installation, ensuring the finished seal matches tested safety standards without guesswork. For projects requiring alternate duct profiles or brand specifications, explore our complete range of cable duct sealing systems and complementary hazardous area cable glands.

Key Features & Technical Capabilities:

• Certified 4-Bar Watertight & Gas-Tight: Tested to withstand up to 4 bar water pressure, safeguarding substations and vaults against severe flooding and hazardous gas migration (such as Methane and H₂S).
• Fire Rated Protection: Delivers certified fire resistance (up to 4 hours / A60 ratings in accordance with EN standards) when installed with fire-rated RISE® sleeves.
• 50+ Year Tested Service Life: Age-tested components resist UV exposure, ozone, hydrocarbon immersion, and chemical exposure without degradation.
• Corrosion-Free Construction: 100% non-metallic design eliminates corrosion risk and prevents “Corrosion Under Insulation” (CUI) caused by moisture-trapping materials.
• Effortless Cable Re-Entry: Allows contractors to add, remove, or replace cables quickly using a simple coring tool, eliminating the need for destructive teardown.
• Vibration & Acoustic Absorption: Flexible rubber sleeve structure absorbs mechanical movement and dampens structural vibration.

Installation Applications

The CSD RISE duct sealing system is suitable for horizontal and vertical penetrations in electrical substations, DNO power networks, trackside communications, and marine bulkheads. View technical data sheets and approval certifications on the official CSD Sealing Systems website.
