KRASO SD 30 Customisable Split Mechanical Duct Sealing Inserts (SD 30 – T) provide a robust sealing solution for any circular duct size and cable layout. Like all KRASO duct seals, the SD 30 offers exceptional protection, safeguarding against flooding, gas infiltration, moisture and rodent intrusion. This two-component seal installs effortlessly, even in damp or water-flow conditions, making it ideal for demanding environments.
Alternative KRASO SD 30 Part Numbers include: SD 30 – E (eccentric), SD 30 – GF (large flange). Please note, KRASO SD 60 is available too.
Engineered to excel under extreme conditions, the KRASO SD 30 sealing system withstands high water and gas pressures, and resists exposure to hazardous substances. Crafted from premium, non-corrosive stainless steel V2A, it delivers durability and reliability that lasts. With KRASO’s patented Torque Control Nut, installation is straightforward – achieving perfect tension without over- or under-tightening.
This versatile system accommodates duct sizes from 50mm to 500mm and can be fully customised to fit any configuration, with custom-cut holes for the exact cable specifications in each penetration.
