What is Reducer Socket 90x50mm DADEX PPRc ?

 

Dadex’s Polydex is their premium PPRC (Polypropylene Random Copolymer) piping system, featuring antimicrobial properties.

Description:

• A straight reducing fitting with socket ends on both sides.
• One end accepts a 90mm outer diameter (OD) PPR pipe, the other a 50mm OD pipe.
• Color: Typically green (antimicrobial Polydex series).
• Material: High-quality PPRC Type-3, corrosion-resistant, non-toxic, with smooth inner surface for low friction loss.

Specifications:

• Sizes: 90mm x 50mm (larger end 90mm OD, smaller end 50mm OD).
• Standards: Conforms to DIN 8077/8078 (pipes) and DIN 16962 (fittings); similar to international PPR standards.
• Temperature Resistance: Up to 95°C continuous (short-term higher).
• Compatible with Dadex Polydex PN25 pipes and fittings (fittings often imported from premium partners like Wavin Ekoplastik).

Usage:

• Primarily for hot and cold potable water supply in residential, commercial buildings, hospitals, hotels, schools, and offices.
• Other applications: Compressed air systems, chemical transport (resistant to many chemicals), rainwater harvesting.
• Commonly used in main lines reducing to branch lines for efficient distribution.

Installation:

• Steps:
  1. Cut the pipe ends squarely using a pipe cutter.
  2. Chamfer/deburr the edges and clean with isopropyl alcohol.
  3. Mark the insertion depth on the pipe (per manufacturer table; typically ~40-50mm for 90mm, ~30mm for 50mm).
  4. Heat the pipe ends and fitting sockets simultaneously using a PPR welding machine (set to ~260°C).
  5. Heating time: Approx. 30-40 seconds for 90mm, 15-20 seconds for 50mm (follow exact times from welder manual).
  6. Quickly remove from heater and insert pipes into respective sockets straight (no twisting).
• Tools needed: PPR welding kit, pipe cutter, chamfer tool.
• Always perform pressure testing after installation. Joints are leak-proof and maintenance-free.
