Mechanical Cable & Pipe Duct Sealing Systems

Enhance your installations' security with Universal Kraso Retrofit Mechanical Duct Seals—the leading solution for circular mechanical duct sealing, offered in sizes 100mm, 125mm, 150mm, and 200mm. These circular cable transits provide a universal, off-the-shelf solution for effective cable and pipe duct sealing, delivering robust protection across multiple industries.

Perfect for data centres, battery storage sites, renewable energy facilities, and ducts prone to water ingress, these re-enterable mechanical duct seals defend against water, gas, and rodent intrusion. With straightforward installation—even in wet conditions—Kraso’s patented torque control nut ensures correct tightening without a torque wrench. Each seal endures pressures up to 2.5 bar (equivalent to 25m of water) and resists toxic gases and hydrocarbons.
