Hauff-Technik HRD 100 -SG -1 Annular Space Seal for Cable Diameter 25-29 mm, EPDM/Stainless Steel

The Hauff-Technik HRD 100 -SG -1 is a high-quality annular space seal designed for sealing one cable in core drillings or wall sleeves with a diameter of 100 mm. This mechanical compression seal provides reliable water and gas tightness up to 2.5 bar, making it ideal for demanding infrastructure applications. The split design (Segment Gasket) allows for easy retrofitting around existing cables without disconnection.

Advantages

• Dry installation – no curing time, immediate sealing
• Split design enables retrofitting without cable disconnection
• Pressure tight up to 2.5 bar (water and gas)
• UV and chemical resistant EPDM seal
• Stainless steel clamping plates and bolts for corrosion resistance
• Wide temperature range from -30°C to +100°C

Suitable for

• Sealing single cables in core drillings and wall sleeves
• Water and gas tight sealing in building services, utility tunnels, and industrial plants
• Retrofitting seals around existing cables
