Material: Most are made from UV-resistant Polypropylene (PP). Premium variants use "Virgin PP" or Polycetal for enhanced resistance to physical impact and chemical cleaning agents.
Pressure Ratings: Standard drip joiners typically support operating pressures up to 2 kg/cm² (approx. 30 PSI). Heavy-duty versions may have pressure ratings as high as PN10 (10 Bar) or 100 PSI.
Standard Sizes: Common nominal diameters include 12mm, 16mm, and 20mm. Reducing joiners, such as 12x16mm, are also available for transitioning between different pipe sizes.
