| Nominal Diameter (PPR Side) | 25 mm (socket fusion compatible) |
| Thread Size (Brass Female Insert) | 3/4″ (BSP or NPT, depending on regional standards) |
| Material | PPRc (Polypropylene Random Copolymer) body with brass insert |
| Pressure Rating (PN) | 25 bar (at 20°C; derates to ~5 bar at 95°C) |
| Temperature Range | -20°C to +95°C (suitable for hot and cold applications) |
| Color | Green (standard for PPR hot/cold water systems) |
| Standards Compliance | DIN 16962, TS EN ISO 15874 (PPR Type 3), NSF-certified for potable water |
| Weight (Approximate) | 0.1–0.15 kg per unit |
| Dimensions (Approximate) | Outer diameter: ~34 mm; Length: ~50–60 mm |
| Certifications | Corrosion-resistant, lead-free brass, UV-stabilized for short-term exposure |
| Origin | Manufactured in UAE by Hepworth (Q-Therm series) |
These specs ensure compatibility with standard PPR fusion tools and threaded metal fittings, with low thermal conductivity for energy efficiency.
Usage
This fitting is ideal for hot and cold water distribution systems in residential, commercial, and industrial settings. It is primarily used to:
- Change Flow Direction: Provides a 90-degree bend while transitioning from a welded PPR pipe (butt-fusion or socket-fusion on the 25 mm side) to a brass-threaded female connection (e.g., to a metal valve, pump, or faucet on the 3/4″ side).
- Applications:
- Indoor plumbing for potable drinking water supply (cold water up to 25 bar).
- Hot water recirculation systems, underfloor heating, and central heating (up to 95°C).
- Air conditioning and radiant floor heating in buildings.
- Installation Notes:
- Use socket fusion welding for the PPR side (requires a fusion machine heated to ~260°C).
- Thread the 3/4″ male counterpart (e.g., pipe or fitting) into the brass insert with PTFE tape for sealing.
- Avoid over-tightening to prevent damage to the plastic body.
- Suitable for pressurized systems; pressure derates with temperature (e.g., 10 bar at 60°C).
- Advantages in Usage:
- Durability: Resistant to chemicals, rust, calcification, and stress cracking; service life >50 years.
- Efficiency: Low thermal expansion (up to 73% reduced with fiberglass-reinforced variants in the series), sound insulation, and energy savings due to minimal heat loss.
- Hygiene: Non-toxic, smooth bore prevents bacterial growth, making it safe for potable water.
- Ease: Lightweight for simple transport and installation; no special tools beyond standard PPR fusion equipment.
