310 Irish Compression Reducing Coupler (Offset)

The 310 Reducing Coupler is a brass compression fitting used to connect two different diameters of Irish Imperial pipe. These fittings allow for a clean transition when stepping down pipe sizes in water or heating systems. Manufactured for the Irish market to IS EN 1254-2 standards, they ensure a secure fit for Irish copper and PEX pipe that standard metric fittings cannot provide. The mechanical compression joint creates a permanent, leak-proof seal using only basic tools, making it an efficient solution for both residential and commercial plumbing.

Key Features

• Manufactured to IS EN 1254-2 standards

• Corrosion-resistant brass construction

• Designed for transitioning between different pipe diameters

• Compatible with Irish Imperial copper and PEX barrier pipe

• Mechanical nut and olive joint requires no heat or soldering

• Suitable for hot and cold water and central heating applications

Technical Note

These are Irish Imperial reducing fittings. The most common domestic transition is from 3/4 inch to 1/2 inch. Please note these sizes are specific to the Irish market and are not compatible with 22mm to 15mm metric pipework. When installing with PEX or Qualpex pipe, the appropriate pipe inserts or liners must be used to ensure a secure joint.
