PVC drainage fittings are commonly used connection components in building drainage systems, primarily serving to connect, redirect, branch, and facilitate maintenance of drainage pipelines.
Main Types:
Three-way/four-way fittings: Used for pipeline branch connections, including inclined three-way (recommended) and straight three-way types. Elbows: Available in 45° and 90° angles, designed to change pipeline direction. Expansion joints: Absorb thermal expansion/contraction of pipelines and prevent deformation. Inspection ports: Used for pipeline maintenance and cleaning. Water traps: Include P-shaped and S-shaped types to prevent odor backflow. Size-specific couplings: Connect pipelines with different diameters. Cleaning ports: Facilitate pipeline clearance in case of blockages.
