Union taper seat, ISO/EN U12
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.
- Torque and notes for installation please find in "Technical Product Notes".
- 374 G ... refers to the thread size G according to ISO 228 of the union nut 374.
