A HDPE compression reducing tee fitting is used to tee off a metric HDPE pipe, to add in a smaller size outlet to a PE Pipe. PP Compression tee reducers are often used to supply water or other fluids to an area from a main pipeline, as they have a smaller off-take (and therefore less flow) than the original pipeline.
With a size range from 25*20*25 mm to 110*90*110 mm, compression reducing tee fittings match common pipe sizes. HDPE Compression reducing tees are suitable for water and other similar fluids, with pressures up to 16 bar, however this varies with the ambient temperature and temperature of the pipe contents. Reducing tee compression fittings are made from high quality PP-B material that is resistant to etching by numerous chemical substances, and to UV rays, and are suitable for outdoor use.
Compatible with PELD, PEHD, PE40, PE80 and PE100 pipes, HDPE compression reducing tee fittings may also be known as compression reducing tees, compression tee reducer fittings or poly pipe outlet tee joiners.

PP compression reducing tee fittings are consisted of 5 palstic accessories:

Benefits Of HDPE Compression Fittings
There are multiple benefits to using HDPE compression fittings in your piping systems. Some of the main advantages include:
Easy to assemble and disassemble without the need for special tools
Low maintenance over time, which makes the piping system last longer
No soldering required, which is especially beneficial for areas where no soldering is allowed
Light-weight in comparison to other materials, which assists in making the assembly quick and more effective
Leak-free jointing is ensured via heat-infused joints to ensure strong connections
Leak-free connections, provided they are installed correctly
Corrosion resistant due to being HDPE. They won’t rust or disintegrate, even after continuous exposure to water or liquids
Can handle water surges due to excellent water hammer capabilities
