What is Dadex Nikasi upvc Elbow 45 degree 75mm ?
The Dadex Nikasi UPVC 45-degree Elbow (75mm) is a versatile drainage fitting available in two primary joining methods: Solvent Weld (chemical bonding) and Rubber Ring/Push-Fit (mechanical seal).
1. Product Description
The 45-degree elbow allows for a gradual change in the direction of a pipeline.
-
The Solvent Joint version features a smooth internal socket for permanent bonding.
-
The Push-Fit version includes a groove with a factory-fitted rubber EPDM ring, allowing for thermal expansion and contraction.
2. Technical Specifications
Dadex Nikasi is manufactured to resist the harsh environmental conditions of Pakistan, including high UV exposure and varying soil chemistry.

| Wall Thickness | Designed to withstand underground soil pressure and impact |
3. Usage: Drain, Sewer, and Ventilation
The 75mm 45-degree elbow is the “workhorse” of residential plumbing:
-
Drain & Sewer: Used to transition horizontal waste lines into vertical stacks. The 45-degree angle prevents “sludge buildup” that common 90-degree bends often cause.
-
Ventilation: Essential for Vent Stacks. It routes air through the plumbing system to prevent vacuum siphoning (which sucks water out of traps/p-traps) and allows sewer gases to exit safely at the roofline.
-
Rainwater: Used in downspouts to navigate around building cornices or architectural features.
4. Installation: Solvent Joint vs. Push-Fit
A. Solvent Joint Installation (Permanent)
-
Prep: Clean the pipe end and the inside of the elbow with a dry cloth.
-
Apply: Use Dadex UPVC Solvent Cement. Apply a thin layer to the fitting and a thicker layer to the pipe.
-
Insert: Push the pipe into the 45° elbow and give it a 1/4 turn to distribute the cement.
-
Hold: Hold for 30 seconds. Do not move for 5 minutes.
B. Push-Fit/Rubber Ring Installation (Flexible)
-
Chamfer: The pipe end must be beveled (chamfered at 15°) to avoid tearing the rubber ring.
-
Lubricate: Apply a thin layer of Dadex Rubber Lubricant (do not use oil or grease) to the pipe end and the ring.
-
Insert: Push the pipe into the socket until it hits the stop, then pull it back about 10mm. This “gap” allows the pipe to expand and contract during hot/cold weather without cracking.
5. Key Advantages
-
Mirror Smooth Interior: Prevents scaling and internal blockages.
-
Corrosion Proof: Unlike cast iron or GI pipes, UPVC will not rust or react with acidic waste.
-
Lead-Free: Environmentally friendly and safer for handlers.
-
High Flow Rate: The 45-degree geometry maintains high velocity for solids in the sewer line.
Comparison Summary
| Feature | Solvent Joint | Push-Fit (Z-Joint) |
| Installation Speed | Moderate (Wait for glue) | Fast (Immediate) |
| Expansion Handling | Poor (Requires expansion joints) | Excellent (Built-in) |
| Ease of Repair | Hard (Must cut pipe) | Easy (Can be disassembled) |
| Best For | Internal high-vibration areas | Underground or long vertical stacks |
