Electrofusion Reducing Tee fittings
Precise Diameter Reduction & Flexible Adaptation: Main pipe and branch pipe calibers can be customized however you need-like DN100×DN50, DN150×DN100, stuff like that. The diameter reduction transition's smooth, no steps at all. Perfect for unequal-diameter pipe network splitting or combining-no need for extra diameter-changing parts. Saves a lot of hassle, honestly.
Targeted Electrofusion Design: We adjust the heating wire distribution density for main and branch pipes based on their calibers. Makes sure heating's even, and different caliber connections fuse really firm. Sealing performance? Doesn't get affected by the diameter difference-total peace of mind.
Light Weight & Easy Construction: The product's light, super easy to carry and transport. Electrofusion installation's simple too-ordinary construction workers can handle it after a little training. Cuts down construction time big time, boosts efficiency.
Long-Term Stability: Works steady even in extreme temps-from -40℃ to 60℃. Stands up to UV radiation, aging, and soil settlement too. Service life's over 50 years, so later maintenance costs are really low. No frequent replacements needed.

Product Advantages
The reducing tee electrofusion fitting's a special accessory for unequal-diameter HDPE pipe networks. It solves that tricky problem of connecting unequal-diameter pipeline branches-something that used to be a hassle. You'll find it used a lot in industrial park variable-diameter pipelines, agricultural irrigation zonal transport, municipal water supply and drainage graded transport, and other similar fields.
We make it with virgin PE100 raw material-hygienic, non-toxic, no heavy metal leaching. Safe to use for drinking water, industrial fluids, and other multi-medium transport. CNC precision processing keeps the diameter reduction angle accurate, and the inner wall's arc transition cuts down fluid resistance. No medium buildup, no pipeline clogs-super reliable.
It supports electrofusion welding, fits all DN20-DN2000 full-series caliber combinations, and adapts to PN6-PN25 pressure grades. For overseas customers, we offer one-on-one technical guidance and FOB/CIF port delivery services. Helps you get your project built efficiently, no delays.
