318 Irish Compression Tee (Offset)

The 318 Tee Offset is a high-quality brass compression fitting used to create a three-way junction where at least one branch of the pipework is a different size. These reducing tees allow for a seamless transition when branching a smaller feed off a larger main line. Manufactured for the Irish market to IS EN 1254-2 standards, they provide a precision fit for Irish copper and PEX pipe systems. These fittings are essential for efficient plumbing and heating layouts, providing a secure and leak-proof mechanical joint without the need for heat or soldering.

Technical Note

These are Irish Imperial fittings. Common domestic offset sizes include reductions from 3/4 inch to 1/2 inch. These sizes are specific to the Irish market and are not interchangeable with UK or European metric fittings. When installing with PEX or Qualpex pipe, the correct size pipe insert or liner must be used in all ends of the fitting to maintain the integrity of the joint.
