Material: Generally manufactured from high-quality engineering plastic, specifically Polypropylene (PP) or Polypropylene Co-Polymer (PPCP). This material ensures the joiner is non-corrosive, and resistant to heat, chemicals (like agrochemicals), and wear.
Size/Diameter: The standard sizes are 16 mm and 20 mm to fit corresponding drip lateral pipes or mainlines. They are also reportedly available in 12 mm and other customized sizes.
Connection Type: They feature a barbed or "push-fit" design with sharp-edged barbs that create a tight, secure, and leak-proof seal without requiring special tools.
Durability: They are UV-stabilized to protect against deterioration from sunlight exposure, making them suitable for long-term outdoor agricultural and gardening applications.
Usage: The primary use is to connect two ends of a drip irrigation pipe to extend the system or repair a damaged section of the pipe.
Pressure Rating: Typically designed for low-pressure poly tubing, with some mentioned operating pressures up to 2 kg/cm² or 4 bar, and a maximum working pressure of around 300 kpa or 8 kg for certain robust variants.
