The gasket is a transition and sealing element with a diameter of 15 mm, mainly made of rubber material. These types of seals are used to create a tight fit in pipe, hose or equipment passages. The 15mm size is the preferred size for systems with moving or fixed transitions (e.g. water, air, gas lines). The rubber structure of the product increases flexibility and sealing properties, it is easy to adapt to the pipe during assembly. Its black color helps hide corrosion and pollution for aesthetic and practical purposes. In the systems used, proper seal selection is critical for passage, sealing, and longevity. This product requires determination of the pipe diameter, static and dynamic load conditions of the link, and system operating conditions (temperature, pressure) prior to installation.
