Reducers

Step between different pipe diameters cleanly and maintain smooth water circulation with our range of high-performance solvent weld reducers and reducing bushes. Engineered specifically for aquatic plumbing systems, filter houses, and equipment manifolds, reducer fittings provide the strength and tight dimensional tolerances needed to connect mismatched pipe sizes securely across your filtration circuits.

Manufactured from tough, fish-safe PVC-U and ABS polymers, our collection features solvent weld reducing bushes, socket reducers, and stepped adaptors designed to chemically fuse directly with standard rigid pipe and fittings using solvent cement. Reducing bushes fit flush inside existing fitting sockets to downsize ports without adding bulk to compact manifolds, while reducing sockets join two different pipe sizes inline. Designed with smooth internal transitions, these fittings minimise frictional resistance and turbulence, preventing debris from catching while maintaining optimal pump delivery rates.

Available in standard plumbing step-downs ranging from 4 inch to 3 inch, 4 inch to 2 inch, 3 inch to 2 inch, 2 inch to 1.5 inch, and smaller auxiliary branch sizes, explore our complete reducers collection to find dependable, builder-approved transition fittings engineered for reliable, leak-free performance.
