110mm and 50mm PVC fittings are essential components in plumbing and drainage systems, designed for different pipe sizes and applications. The larger 110mm fittings, such as elbows (90° and 45°), couplers, tees, reducers, end caps, and access caps, are commonly used in soil, waste, and vent (SWV) systems for residential, commercial, and industrial drainage. These fittings allow for directional changes, pipe extensions, branch connections, size reductions, and system maintenance. On the other hand, 50mm PVC fittings, including elbows, couplers, tees, reducers, end caps, and saddle clamps, are used in smaller-scale systems like residential waste drainage, irrigation, and vent piping. They serve similar functions but on a smaller scale, providing flexibility for pipe routing, connections, and system termination. Both sizes of PVC fittings are valued for their durability, corrosion resistance, and ease of installation, making them integral to a wide range of piping systems.
