The UNI White Compression Waste Swept Tee – 40 mm is a plumbing fitting designed to create a smooth three-way junction in 40 mm waste pipework. It is used in domestic drainage systems to combine waste flows from two outlets into a single drain line with minimal resistance.

Function & Purpose

This swept tee connects three lengths of 40 mm pipe: two inlets (for example from a bath, shower, or sink) and one outlet toward the main waste. Its swept (curved) branch provides a gentler flow path compared with sharp-angled fittings, improving drainage performance and reducing the risk of blockages. The compression design uses a nut and olive to secure the pipes and form a reliable, watertight seal.

Compatibility

The fitting is designed for 40 mm waste pipework, a common size for larger domestic waste connections such as shower, bath, or combined drainage runs. It connects with other 40 mm compression components in household drainage systems.

Design & Build Quality

Finished in white for a neat appearance where pipework is visible, this compression swept tee is made from durable materials suited to typical waste system pressures and conditions. The compression joints allow secure installation without solvent, heat, or specialist tools, and also make it easier to disassemble if changes or maintenance are needed.

Ideal Applications

This 40 mm swept tee is ideal for bathroom and kitchen waste systems where two waste outlets need to join into a larger drain line. It’s particularly useful in situations where smoother flow and reduced blockage risk are desired, such as combining bath and shower wastes or integrating multiple waste branches into a single drain.
