Winteb GO TO WEBSITE Founded in 1952 Winteb has grown into the world's largest producer of seawater resistant aluminium (DIN1725) Air Pipe Heads. Winteb has been producing these Air Pipe Heads since 1985, starting with the WIKO5000 series. In the year 2000 Winteb developed the WIN2000 air pipe head series which set the standard in air venting. This series is also produced out of seawater resistant aluminium. The advantages of seawater resistant aluminium over our competitors who use cast-iron, welded hot dipped iron/steel constructions or stainless steel, is that aluminium (DIN1725) will not corrode and requires no maintenance. Furthermore the WIN2000 series has a space and weight saving design that is revolutionary compared to other Air Pipe Heads.
