Product description
Brief Introduction
This PVC-U H-type drainage connector features an integrated expansion-compensation structure and built-in rubber sealing rings. Designed to interconnect two DN110 drainage stacks, it helps balance air pressure and accommodate thermal expansion and contraction in PVC-U drainage systems.
Key Advantages
- One-piece injection molded from virgin PVC-U material for excellent strength and structural stability.
- Integrated expansion joint compensates for thermal movement and helps prevent pipe cracking.
- Built-in black rubber sealing rings provide reliable sealing and leakage protection.
- H-type interconnection design balances air pressure between drainage stacks, reduces drainage noise, and helps prevent water-seal failure.
- Smooth inner walls ensure efficient flow while reducing dirt buildup and blockage.
- Manufactured to standard dimensions for residential and commercial building drainage projects.
Applications
Dual-stack bathroom drainage systems in residential buildings, high-rise sewage stacks, residential drainage renovations, combined rainwater and sewage pipe networks, and pressure-balancing upgrades for indoor PVC-U drainage systems.
