🔩 Overview — Dadex Nikasi UPVC Tee 110 mm

A Dadex Nikasi UPVC Tee (110 mm) is a three-way plumbing fitting used to connect three sections of 110 mm uPVC pipe in a drainage, sewer, and ventilation (SWV) system. It forms part of the Dadex Nikasi range, a brand line commonly used in Pakistan for building drainage installations including soil, waste, and vent stacks.

• Material: Unplasticized Polyvinyl Chloride (uPVC) — rigid, corrosion-resistant plastic.

• System Type: SWV — Soil (toilets), Waste (grey water), Vent (air escape).

• Nominal Diameter: 110 mm (approx. 4″). Typical for main building drainage stacks.

It’s available in two common jointing types:

1. Push-fit / Rubber Ring Joint

   • A flexible sealing ring inside the socket.

   • Pipes are simply pushed into the fitting to achieve a watertight joint.

   • Useful for easier installation and future dismantling.

2. Solvent Cement Joint (Solvent Weld)

   • A chemical adhesive that welds pipe and fitting together permanently.

   • Creates a stronger, leak-proof connection that isn’t easily reversible.

📐 Description Dadex Nikasi upvc Tee 110mm

A Tee fitting has one inlet and two outlets at 90°, forming a “T” shape. For 110 mm, it connects:

• One straight-through pipe run (vertical or horizontal main drain),

• Two branch pipe connections (often leading to fixtures like basins, floor traps, or vent stacks).

This means it splits or joins the flow in a drainage network.

📊 Typical Specifications

While specific dimensions and tolerances depend on manufacturer drawings, Dadex Nikasi fittings typically conform to:

❗ Important: In drainage systems like this, “pressure rating” is not the same as for potable water pipes. It’s designed for gravity flow and internal vent pressures only, not for high-pressure water supply.

🚰 Primary Uses & Applications

Dadex Nikasi 110 mm Tee fittings are mainly used in:

✨ Soil & Waste Drainage

• Connecting waste lines from toilets, sinks, floor drains, toilets, and baths to the main waste stack.

🌬 Ventilation (Vent) Piping

• Allowing vent pipes to be tied into the drainage stack so sewer gases can escape and the system remains balanced.

🛠 Branch Connections in Drain Work

• Creating branch lines from a main horizontal drain or vertical stack toward fixtures.

🧱 Rainwater / Storm Contributions

• In some buildings, drainage tee fittings will incorporate rainwater overflow into the overall sewer network.

🧱 Installation Notes

✔ Push-fit Joint

• Clean pipe ends and internal rubber seal.

• Apply lubricant (soap solution or approved silicone) on the pipe end.

• Push the pipe into the fitting until fully seated.

• Slight pull-back (a few mm) may be needed to allow thermal movement (common practice).

✔ Solvent Cement Joint

• Clean and degrease pipe end and fitting socket.

• Apply uPVC solvent cement on both surfaces.

• Insert and rotate slightly to spread adhesive.

• Hold for 20–30 s until initial set; full cure ~24 h for pressure testing.
