Puddle Flanges (VPF)

Watertight up to 10 bar and easy to install, FRANK puddle flanges have been designed specifically for the pressure-tight installation of pipelines in concrete walls, tanks, shafts, foundation plates, manholes and basements.

Installed on the external pipe surface to act as a barrier, they diffuse gases and hydrocarbons and are suitable for all standard steel, plastic, clay, concrete and cast iron pipes from DN20 to DN3200 mm making them a perfect solution for any application.

Puddle flanges applications:

  • To prevent water or gas getting into buildings via pipe penetrations
  • Domestic and commercial developments
  • Suitable for use with all smooth walled pipes provided that the pipe surface, at the point of
    installation, is clean, smooth and free of pores or surface imperfections
  • Most pipe sizes can be accommodated from 20mm through to 3200mm diameter
  • Installed on pipes during construction where water penetration has to be prevented

Materials

FRANK puddle flanges are manufactured in EPDM and NBR. EPDM is chemically resistant to a wide range of substances and offers outstanding weather and ozone resistance. For applications in connection with oil and petrol, FRANK puddle flanges made in NBR are the preferred option

Installation

Thanks to the easy-lock tension bands, installing a FRANK puddle flange takes only a few minutes. The puddle flange is mounted by hand on the pipe and secured with the supplied tension bands. A screwdriver or 6mm nut driver can be used to install the tension band on pipes of up to 315 mm in diameter.

For larger pipes, use a clamping tool. Our puddle flange installation kits (DN20 to DN315 mm) now come with an easy-Lock function that allows for even faster installation on the pipe.

  • Tested up to 10 bar water pressure
  • Easy to install, cost effective solution
  • Can be installed in walls, floors and ceilings
  • Good chemical resistance
