Size/Diameter: The most common sizes are 16 mm and 20 mm (outer diameter) for connecting to corresponding PE drip irrigation pipes.
Material: They are typically manufactured from tough engineering plastic, such as Polypropylene (PP) or High-Density Polyethylene (HDPE).
Connection Type: These are usually barbed or "push-fit" straight connectors designed to provide a secure, leak-proof connection by gripping the inner wall of the pipe.
Resistance: The fittings are designed to be non-corrosive, resistant to chemicals, and UV-stabilized to withstand prolonged sun exposure and outdoor conditions.
Operating Pressure: They are generally suitable for typical drip irrigation pressures, which often range from low pressure up to a maximum of around 4-6 bar (approximately 58-87 psi).
