Push-fit plumbing systems have become the gold standard for building drainage because they end recurring leaks, complex joints, and noisy wastewater flow. Newflax—from the Giti Pasand Group—is a locally engineered, third-generation PP-C solution. With precision-molded sockets and EPDM O-rings, it delivers true push-fit installation and high mechanical strength that simplify work for contractors and MEP engineers.
Why Newflax excels in mission-critical projects
- Adhesive- and heat-free jointing
Each socket includes an EPDM O-ring. Push the spigot end in to achieve instant, durable sealing—no flame, welding machine, or insulated gloves. - Outstanding impact & chemical resistance
Impact strength: 25 J/m²; chemical compatibility across pH 2–12 for strong detergents, mild acids, and on-site shocks. - Low internal roughness: 0.007
The smooth bore slows scaling and maintains high flow, minimizing sudden narrowing and chronic blockages common in PVC lines. - Integrated fire performance
Halogen-free additives limit flame spread; classification DIN 4102, Class B1.
Explore the Newflax product family
| Product series | Diameter range (mm) | Signature application | Key differentiator |
|---|---|---|---|
| Pushfit | 50–160 | Concealed or exposed runs in residential & office buildings | Balanced performance and strength |
| TrueSilent | 50–110 | Hotels, hospitals, premium residences | Flow-noise reduced to 6–17 dB |
| B / BD | 50–160 | Exposed runs (B) and buried lines (BD, yellow cap) | Thicker wall; enhanced impact resistance |
Noise reduction in the TrueSilent series
A three-layer core with mineral filler and silicone rubber absorbs hydraulic shock. Result: even late-night discharge remains quiet for occupants.
Applications beyond building drainage
- Wastewater and rainwater discharge in high-rise complexes
- Condensate routing for chillers and air-handling units
- Branch connections to municipal or rural sewers
- Collection of lab effluent with moderate chemical load

| Thermal conductivity | 0.23 W/m·K | DIN 52612 |
| Elongation at break | 800 % | ISO 527-2 |
Design tip for engineers
Thanks to the low expansion coefficient, one sliding clamp every 3 m is sufficient on vertical risers. This reduces supporting hardware by about 20–30 %.
Installation best practices
- Square cuts with a fine-tooth saw and a set square; then deburr with a conical tool.
- Lubricate the O-ring with a standard silicone lubricant to lower insertion force.
- Mark the insertion depth with a waterproof marker—useful for quality checks during pressure testing.
- Thermal movement: on long horizontal runs, include an expansion joint every 12 m.
