# Malleable Cast Iron Compression Fitting for Steel Pipes - Type EKF - with NBR-Sealing – GEBO 01.220.07.07

The original since 1936 - gebooriginal malleable cast iron compression fittings for permanent use! GEBO's original product is the malleable cast iron compression fittings from the gebooriginal range. Then as now, they are not only flexible and available in various designs, but are also suitable for permanent use. The different compression fitting series are suitable for various pipe types and media. They are force-fitting, i.e. resistant to tension and shear. This means that compression fittings are suitable for most applications across the board and can be used optimally in various sizes. The compression fitting technology eliminates the need for time-consuming thread cutting and welding, which is why working with gebooriginal is particularly time- and cost-saving.
