Cosmoplast UPVC Reducer, 160mm x 110mm, Step-Down Connector for Mixed-Diameter Drain Lines - Grey

This reducer connects a 160 mm UPVC pipe to a 110 mm UPVC pipe, allowing a smooth diameter transition in plumbing systems for both residential and commercial installations.

Material: UPVC; Color: Grey; Size: 160 mm to 110 mm reducer; Use: reduces pipe size from 160 mm to 110 mm in UPVC piping; Durable and corrosion-resistant with good chemical tolerance.

General installation steps: 1) cut and deburr the pipes to ensure clean ends; 2) apply compatible UPVC primer to the pipe ends and the reducer socket; 3) apply UPVC solvent cement to both the pipe and reducer socket; 4) push the 110 mm side into the reducer first, then align the 160 mm side; 5) hold steady until the cement sets and cure per product guidelines.

The reducer transitions from a 160 mm pipe on one end to a 110 mm pipe on the other end. Install with the 160 mm end connected to the larger pipe and the 110 mm end to the smaller pipe, ensuring proper alignment for a leak-free joint.

Ideal for connecting a larger diameter main line to a smaller distribution line, bridging sections of UPVC piping in both new installations and piping upgrades in water supply or drainage systems.

Made from UPVC, it offers strong corrosion resistance, chemical resistance, and can withstand typical temperatures encountered in plumbing. It has no moving parts, so maintenance is minimal—regularly inspect joints for leaks and ensure proper installation.

Alternative reducers on Fepy include: 1) Cosmoplast 110mm x 90mm UPVC Reducer Grey (https://fepy.com/product/cosmoplast-110mm-x-90mm-upvc-reducer-grey) — smaller step-down option for tighter spaces. 2) Cosmoplast 200mm x 160mm UPVC Reducer Grey (https://fepy.com/product/cosmoplast-200mm-x-160mm-upvc-reducer-grey) — larger diameter, suitable for higher flow applications. Both use similar UPVC material and installation methods, offering comparable durability with different size transitions.

Identify the outer diameters of the pipes you’re joining (in this case, 160 mm and 110 mm). The reducer should connect those two sizes with a smooth transition. Verify that both pipes are compatible with UPVC fittings and that the solvent cement/primer you use is approved for UPVC piping.

UPVC reducers are widely used for potable water systems and offer good chemical resistance. This reducer should be compatible with typical potable-water installations, but always confirm local codes and product specifications for your exact application and any aggressive chemicals in the system.

Wear appropriate PPE (gloves and eye protection). Ensure work area is dry and well-ventilated. Use proper UPVC primer and cement, apply evenly, and avoid over-application to prevent slip hazards. Allow adequate curing time before system pressurization and inspect joints for alignment and leaks after installation.

Store in a clean, dry place away from direct sunlight and severe temperature fluctuations. Keep the reducer free from physical damage; handle with care to avoid scoring or cracking the socket faces, which could affect fit and seal integrity.
