Spare Packs for Lead pipe

Malleable cast iron fittings are offered in black and hot dip galvanized version. Because of their durability, high mechanical stress and temperature resistance these fittings continuously enjoy great popularity.
The thread according to EN 10226-1 is an universal, standardised jointing technology and ensures a safe use in a broad field of application.
Additionally to the threaded fittings, a compression fitting made of malleable cast iron is available. This fitting, sold under the brand PRIMOFIT, offers a full end load capability and is produced with black or hot dip galvanized surface. It is the time-saving connection of steel-pipeds, PE-piped, lead-pipes and butt-weld steel pipes.

  • Dim. Pb shows the range of the outside diameter of the lead pipe.
  • Dim. St refers to the fitting sizes, which need to be combined with the Spare Packs.
