Interflow UK offers the original and the best

Interflow UK has been appointed UK distributor for FRANK puddle flanges, which are suitable for all standard pipes in steel, plastic, stoneware, concrete and cast iron from 20 mm to 3200 mm diameter, have been specifically designed for straightforward on-site installation to provide guaranteed watertight sealing of pipes through concrete walls, foundation plates and manholes.

FRANK puddle flanges are pressure-tight up to 10 bar, preventing the ingress of pressurised water, diffusing media such as gases, including radon, and hydrocarbons like oil and petrol.

The FRANK puddle flange is an extremely flexible product available in a range of versions, it is the easy-to-install, perfect solution for any application and is the cost effective alternative to conventional sealing systems.

Depending on the diameter, FRANK puddle flanges are proven to be tight up to pressures between 8 and 10 bar. They are made in EPDM, which is chemically resistant to a wide range of acids and bases. It also offers outstanding weather and ozone resistance. For applications involving oil and petrol environments, FRANK puddle flanges made in NBR are available and a special radon-resistant version is available to seal against this radioactive gas.

Interflow also distributes HKD systems, the guaranteed sealing solution for service conduits cast into concrete without sleeves. HKD seals are guaranteed watertight up to 4 bar pressure.

Options include the KE Socketless service conduit, KG Wall Ducts and Floor Ducts, together with KG Twin Sockets for installation in pump sumps and where suitability for thin-walled concrete structures is paramount. HKD service conduits are supplied ready for use, requiring no site preparation work prior to installation.

Both FRANK and HKD products offer low-cost, guaranteed sealing of below-ground service entries available ex stock for rapid delivery to site throughout the UK.
