What is Dadex Nikasi upvc Red Bush 75mmx50mm ?

 

A reducing bush (also called a reducer bushing) is a pipe fitting used to connect two different pipe diameters — in this case 75 mm down to 50 mm. It forms part of the Dadex Nikasi UPVC piping system, which is commonly used for soil, waste and vent (SWV) systems in buildings.

• Brand: Dadex Nikasi (manufactured or licensed in Pakistan with collaboration from Wavin Overseas b.v.)

• Material: UPVC (Un plasticized Polyvinyl Chloride) — rigid, corrosion-resistant plastic.

• Colour: Usually light grey (typical for SWV systems).

• Type: Reducing Bush / Reducer fitting — reduces pipe size from 75 mm to 50 mm.

📊 Description & Purpose

🔹 What It Does

A 75×50 mm reducing bush lets you transition from a 75 mm pipe to a 50 mm pipe within the same drainage or venting system. It fits inside a larger fitting or branch and provides a connection point for the smaller diameter pipe.

This is useful when:
✔ You need to branch into a smaller pipe.
✔ You’re connecting a vent, trap, or branch line of different size.
✔ You’re adapting between pipe runs within drainage, sewer, or waste systems.

🔹 System Type

The Dadex Nikasi system is designed for soil, waste, and vent drainage in building plumbing — including toilets, sinks, floor drains, roof drainage, stormwater, and vent stacks.

📏 Specifications Dadex Nikasi upvc Red Bush 75mmx50mm

While specific dimensions depend on exact product drawings from Dadex, these are standard expectations:

Note: Unlike pressurized water systems, SWV drain installations rely on gravity rather than internal pressure — so pressure ratings (like PN numbers) are not typically specified.

🛠️ Installation Guide

Dadex Nikasi UPVC fittings such as reducing bushes are installed using standard UPVC plumbing practices:

🧰 Tools & Materials

✔ Measuring tape
✔ Marking pencil
✔ UPVC pipe saw / cutter
✔ Deburring tool / file
✔ UPVC solvent cement (if solvent joint type)
✔ Clean cloth (to remove dirt/debris)

🔧 Step-by-Step Installation

1. Measure & Cut Pipe

   • Cut the 75 mm and 50 mm pipes squarely to the required length.

   • Ensure ends are free of burrs and debris.

2. Dry Fit Check

   • Fit the reducing bush into the 75 mm pipe or fitting first.

   • Check alignment of the 50 mm pipe into the smaller socket.

3. Apply Solvent Cement (for solvent joints)

   • Apply an even coat of UPVC solvent cement to both the pipe and inside the reducing bush socket openings.

   • Immediately insert both pipes into the fitting with a full, smooth push.

4. Hold and Set

   • Hold the pipes in position for 10–30 seconds until the solvent starts to set.

   • Avoid movement during curing.

5. Cure Time

   • Follow the recommended cure time on the cement container (typically 30 min before handling, ~24 h before full load or water flow).

6. Test the System

   • Perform normal drain tests (water or smoke tests) to check for leaks.

Tip: Keep the joint area clean and avoid twisting while solvent cement is setting. Proper marking before joining helps ensure straight alignment.

🔹 For rubber ring type connections, simply push the pipe end into the rubber ring socket until fully seated — no solvent cement needed. Ensure the rubber gasket is clean and lubricated with approved lubricant for smooth assembly.

⚙️ Installation Placement & Usage

📍 Where This Fitting Is Used

✔ Drainage Lines: Connect larger discharge drains (75 mm) to smaller branch drains (50 mm).
✔ Ventilation Stacks: Reduce vertical vent pipe size in roof or sanitary stacks.
✔ Trap Connections: Connect traps (e.g., from floor drains) into larger main stacks.
✔ Waste Systems: Parliament of pipework where waste flow transitions sizes.

🧠 Benefits & Features

✔ Lightweight & Easy to Work With — no heavy tools required.
✔ Corrosion Resistant — unlike metal, UPVC won’t rust or degrade easily.
✔ Smooth Internal Surface — reduces blockages and promotes efficient flow.
✔ Chemical Resistant — suitable for sewer/vent lines with mild chemical presence.
✔ Economical — long service life with minimal maintenance.
