- Working pressure: 0.6~1.6MPa
- Temperature resistance range: -40°C~60°C
We have been manufacturing and selling pipe fittings for more than 20 years, selling low prices and producing high quality pipe fittings are our obvious advantages, welcome to inquire.
The flat-end HDPE connector is a connector specially designed for HDPE (high-density polyethylene) pipe systems. It adopts a flat-end design, which is more stable and can achieve quick pipe connection through hot-melt or electric-melt technology. It is suitable for water supply, drainage, gas and industrial fluid transportation systems. Its core advantages lie in its high sealing, corrosion resistance and easy installation.

Advantages
- Strong corrosion resistance: HDPE material has a long service life of more than 50 years and is resistant to acid, alkali, salt spray and organic corrosion.
- Efficient installation:Compared with traditional flange connection, the efficiency is increased by 60%, and the construction time of each joint only takes 10 to 30 minutes.
- Environmental protection and energy saving: no welding fume pollution, and HDPE material can be recycled up to 100%.
- Low flow resistance design:The inner wall is very smooth, with a roughness coefficient of ≤0.008, and the flow rate is 20%~30% higher than that of metal pipes of the same specifications.
