Biggest Advantages of Choosing Our Chimney Joint Seals

When you repair manholes and sewers, moisture intrusion through the manhole cover presents a problem. At PrimeLine Products, we stock FlexRib frame chimney seals that create a watertight seal between the cover and frame. Let’s take a look at the biggest advantages of choosing these chimney joint seals and coordinating chemical grouting accessories and equipment.

Resists Corrosion

Along with our other chemical grouting supplies, the chimney seals resist corrosion. The corrosive sewer pipe environment degrades all types of metal, but our rubber seals remain strong and free of damage after decades. They withstand thermal expansion and contraction, heavy traffic loads, freeze and thaw cycles, and more. The 50-year lifespan of these seals ensures an excellent return on investment.

Prevents Moisture Intrusion

Automotive fluids, melting rain or snow, rainfall, and leaks all make their way through unsealed manhole covers. Our chimney seals stop this infiltration. The combination of stainless steel wavebands and durable engineered rubber offers easy installation and stays in place for as long as you need it to. The seal achieves water tightness for manhole and joint sealing by moving vertically or horizontally with pressure or changes in temperature or humidity.

Wide Range of Sizes

Our FlexRib chimney seals fit all types of manhole covers. We stock them in six-inch, 8.5-inch, 10.5-inch, and 12-inch sizes with a standard configuration as well as a 9.25-inch extension pipe style. These widths work on all types of sewer rehabilitation projects. The seals pair well with our Avanti chemical grouting and grouting tools.

Protect infrastructure and extend the lifespan of the repairs you do on sewers with our FlexRib seals. They only require minutes to install and they deliver decades of service.
