What is Dadex Nikasi upvc Wye 160mm ?

 

Dadex Nikasi UPVC Wye 160mm is a specialized fitting from Dadex Eternit Limited’s Nikasi series, designed for soil, waste, and vent (SWV) systems in building drainage applications. It is commonly referred to as a Wye (or “Y” branch fitting), which allows a branch line to join the main pipeline at a 45-degree angle for smoother flow transition, reducing turbulence compared to sharp 90-degree tees.

This fitting is part of the Nikasi u-PVC (un plasticized Polyvinyl Chloride) range, primarily used for non-pressure drainage, sewer, waste discharge, and ventilation systems in residential, commercial, and industrial buildings.

Description

• Type: Wye (single branch Y-fitting), sometimes available as reducing Wye (e.g., 160mm x 110mm main to branch).
• Material: High-quality u-PVC (un plasticized PVC), light grey in color.
• Joint Types:
  • Solvent joint (solvent cement weld): Permanent, rigid “cold weld” joint using solvent cement for a strong, leak-proof bond.
  • Push-fit (rubber ring joint): Features an integrated rubber ring (gasket) in the socket for easy insertion and a flexible, watertight mechanical seal. This allows slight movement due to temperature changes and is quicker to install without glue.
• The product name “push fit and solvent joint” indicates availability in both joint styles, depending on the specific variant or supplier stock (solvent is more commonly referenced for Nikasi fittings in many listings, while push-fit/rubber ring is also offered for larger sizes or specific applications).

It is engineered for efficient branching in drainage lines, helping direct flow from secondary pipes (e.g., from toilets, sinks, or vents) into the main stack or sewer line.

Specifications

• Size: 160mm nominal diameter (common for main soil/waste stacks or larger drainage lines).
• Standards Compliance:
  • Nikasi fittings (solvent cement joints): ISO 3633:2002(E) / EN 1329:1999.
  • Nikasi fittings (rubber ring joints): ISO 3633:2002(E) / EN 1329:1999.
  • Pipes (related): Also conform to PS 3214:1992 (Pakistan standard).
• Range Availability: Fittings and pipes in diameters including 40mm, 50mm, 75mm, 110mm, 160mm, and 200mm.
• Key Properties:
  • Lightweight for easy handling.
  • Non-corrosive and chemically resistant (to acids, alkalis, and domestic sewer contents).
  • Resistant to organic growth (no bacterial buildup).
  • Low flow resistance (smooth interior for better hydraulic performance).
  • Self-extinguishing and non-conductive to electricity.
• The Wye is designed for non-pressure applications (gravity flow), not pressurized systems.

Installation

• Solvent Joint:
  1. Clean and dry the pipe end and fitting socket.
  2. Apply Dadex-recommended u-PVC solvent cement evenly to both surfaces.
  3. Quickly insert the pipe into the fitting with a slight twist (1/4 turn) and hold for a few seconds.
  4. Allow curing time as per cement instructions (typically minutes to hours before pressure/flow).
  • Provides a permanent, rigid connection.
• Push-Fit (Rubber Ring):
  1. Clean the pipe end and fitting.
  2. Lubricate the pipe end and rubber ring (with approved lubricant, not oil/grease).
  3. Push the pipe firmly into the socket until it seats fully (past the ring for seal).
  • Quick, no tools or glue needed; allows thermal expansion/contraction.
• General Tips:
  • Use proper alignment to avoid stress.
  • Support pipes adequately to prevent sagging.
  • For 160mm size, often used in vertical stacks or horizontal branches in multi-story buildings.
  • Follow local plumbing codes and Dadex guidelines (technical support available via Dadex offices in Pakistan).

Usage

• Primary Applications:
  • Soil & waste drainage (from toilets, urinals, sinks, showers).
  • Ventilation (vent stacks to prevent siphon age and allow air flow).
  • Rainwater downpipes (in some cases).
  • Branch connections in building drainage/sewer systems.
• Ideal for gravity-fed, non-pressure systems in homes, apartments, commercial plazas, and community buildings.
• Not for underground sewer mains (Dadex Flowline series is for that) or pressurized water supply.
• Advantages make it durable, low-maintenance, and cost-effective over cast iron or other materials.
