Tee Female 20×1/2″ Brass RAKtherm PPRc

Tee Female 20×1/2″ Brass RAKtherm PPRc (PN 25) is a transition fitting used in Polypropylene Random Copolymer (PPR/PPRc) piping systems. It features two socket ends for heat-fusion welding to PPR pipes (typically 20mm diameter) and one female threaded brass end (1/2″ BSP or similar) for connecting to metal valves, faucets, or other threaded components.

RAKtherm is a leading UAE manufacturer (based in Ras Al Khaimah) known for high-quality PPR piping systems designed for hot and cold water applications, including HVAC, plumbing, and water supply in residential, commercial, and industrial settings.

Description

• Type: Female Threaded Transition Tee (or Brass Tee Female).
• Design: PPR body with integrated brass insert/thread for the female end. The brass provides durability and compatibility with threaded metal parts while the PPR body ensures corrosion resistance and easy fusion welding.
• Key Features:
  • Corrosion-resistant (no rust or scaling).
  • Hygienic and food-grade (non-toxic, suitable for potable water).
  • High temperature and pressure resistance.
  • Leak-proof when properly installed via heat fusion.
  • Imported from UAE, often noted for premium quality and compliance with standards like DIN 8077/8078.

These fittings are part of RAKtherm’s comprehensive PPRc range, which includes sockets, elbows, tees, reducers, unions, and various brass transitions.

Specifications (Typical for RAKtherm PPRc PN 25)

• Size: 20mm (PPR sockets) x 1/2″ (female brass thread).
• Pressure Rating: PN 25 (suitable for up to 25 bar at 20°C; derates at higher temperatures, e.g., suitable for hot water up to 90°C continuous or short peaks to 100°C).
• Material:
  • PPR (Polypropylene Random Copolymer) body — high-quality resin for thermal and mechanical strength.
  • Brass insert/thread — corrosion-resistant, often with ribs or hexagonal features for secure integration.
• Temperature Range: 0°C to 90°C continuous, with short-term peaks up to 100°C. Expected service life: ~50 years under standard conditions.
• Standards: Conforms to DIN 8077/8078 and other international plumbing norms. RAKtherm systems emphasize quality assurance and certifications.
• Color: Typically green (common for PPRc) or white/grey variants.
• Dimensions & Weight: Specific values vary slightly by batch; refer to RAKtherm catalogue for exact measurements (e.g., similar fittings weigh around 0.07–0.1 kg per piece). Packing often in small quantities (e.g., 10 pcs).

Note: Always verify exact specs with the supplier or official RAKtherm catalogue, as minor variations exist across production runs.

Usage

• Primary Applications:
  • Hot and cold potable water supply.
  • HVAC systems (chilled/heating water networks).
  • Underfloor heating, central heating, and air-conditioning.
  • Transition points between PPR pipes and metal fixtures (e.g., faucets, valves, boilers, or meters).
• Ideal for branched connections in distribution lines where a 20mm PPR main/branch needs a 1/2″ threaded outlet.
• Suitable for residential, commercial, and light industrial projects due to its reliability, low maintenance, and hygiene.

Installation

PPR systems use socket fusion welding (heat fusion) for plastic-to-plastic joints, which creates a homogeneous, leak-free bond stronger than the pipe itself.

General Steps (Professional installation recommended; follow RAKtherm guidelines):

1. Preparation: Cut pipes squarely, deburr, and clean surfaces. Use proper tools (e.g., PPR pipe cutter, fusion welding machine).
2. Heating: Use a socket fusion tool to heat the PPR pipe end and the fitting socket simultaneously to the recommended temperature/time (depends on size; typically for 20mm: ~5–8 seconds heating).
3. Joining: Quickly insert the pipe into the socket and hold firmly for cooling (a few seconds). Do not twist or adjust after joining.
4. Brass Threaded End: Connect to compatible 1/2″ male threaded components using PTFE tape or approved sealant. Avoid over-tightening to prevent damage to the brass insert.
5. Testing: Pressure test the system after installation.
6. Tools & Accessories: RAKtherm provides welding machines, clamps, and other supports. Follow heating times from their manual for best results.

Important:

• Use only genuine RAKtherm components for compatibility.
• Protect from UV if exposed (or use anti-UV variants).
• For detailed procedures, dimensions, and welding parameters, consult the official RAKtherm PPR catalogue or installation guide (available on raktherm.com or from distributors).
