Technical Structure

The connector consists of only three components and therefore enables quick and easy assembly assembly without special tools. The support tube, which is firmly connected to the base body, brings the plastic pipe into an exactly round shape. plastic tube into an exactly round shape and supports it inwardly, i.e. it maintains the internal pressure against the brass clamping ring of the connector. Even under negative pressure, no pipe deformation occurs. Due to its special contour, the fixed support tube additionally ensures the sealing function.


All components in contact with drinking water are made of high-quality UBA-compliant material. The material is suitable for drinking water hygiene and complies with the legal requirements (Drinking Water Ordinance, UBA list). The reliable brass material ensures a particularly long service life.


No long-term damage due to leaky or porous seals, as the sealing function is performed via the support tube, so no additional seals are required. The clamping mechanism, which has been tested and further developed over decades, in conjunction with the fixed support tube ensures a permanently tight connection. The sealing function is independent of the condition of the outer pipe surface. Thus, pipe grooves on the outer surface have no influence on the tightness.
