Electrofusion Reducing Tee

Electrofusion Reducing Tee

Electrofusion Reducing Tee is a type of pipe fitting used in plastic pipe systems, suitable for branch connections of pipes of different diameters. It adopts the brand-new high-density polyethylene material well-known in the industry, featuring corrosion resistance, anti-aging and a long service life.

Reducing the Branch, Not the Run
When a large main must feed a smaller service line, the simplest layout is a reducer and a tee bolted together. The reducing tee does both in one body: the run passes through at full internal bore while the branch outlet is moulded to a smaller size, so the step-down happens inside the fitting itself.

One Fitting Replaces Two
Combining the reducer and the tee into a single moulding removes an entire joint from the line. Fewer joints means fewer places for a leak to develop, less alignment to manage, and a shorter, tidier segment in an already-cramped trench.

Key features
Run retains its full bore for undisturbed through-flow.
Outline reduced to a dedicated smaller spigot for the service size.
Single-piece virgin PE100 moulding replaces tee-plus-reducer.
Barcode-controlled electrofusion sockets deliver homogeneous welds.
Compact footprint eases installation in tight trenches.
Where a reduced tap helps
Reducing tees are the practical choice whenever a big carrier feeds a smaller consumer line: a trunk main dropping to a service, a manifold feeding thinner laterals, or an irrigation header branching into field outlets of a smaller bore.

Applications
Trunk mains stepping down to service laterals.
Manifold take-offs feeding several smaller lines.
Irrigation headers branching to smaller field outlets.
Borehole risers distributing to reduced distribution pipes.
Installation note
Confirm the run and branch sizes against the pipe being joined, clean and scrape each socket, seat the pipes to the stops, weld in the required orientation and respect the cooling time before the line is pressurised.
