125mm Universal Kraso Retrofit Mechanical Duct Seal – Watertight & Gastight Cable Transit Solution

Description

Secure your installations with our mechanical duct sealing system, the 125mm Universal Kraso Retrofit Mechanical Duct Seal. This mechanical circular cable transit is your optimal solution for sealing cable ducts with pipes and cables correctly, offering an efficient and reliable off-the-shelf universal solution.

Product Description

The Kraso Universal Circular Cable Transit Seal is designed to provide enduring protection against flooding, gas infiltration, humidity, and rodent intrusion. Comprising two components, this retrofit duct sealing system can be effortlessly installed—even in damp environments and areas with flowing water—making it a genuinely re-enterable mechanical duct seal.

It is engineered to excel in the most demanding conditions and withstands high water and gas pressures of up to 2.5 bar (that's 25 metres of water). Crafted from high-quality, non-corrosive stainless steel V2A, it resists toxic and hazardous substances, including Radon, Hydrogen Sulphide, Methane, Chlorine gas, and hydrocarbons.

The seal features Kraso's unique patented torque control nut, simplifying installation and ensuring all tightening nuts are neither under-tightened nor over-tightened—no torque wrench required.

Key Features
