What is Female Socket 40×1-1/4″ RAKtherm PPRc ?

 

Female Socket 40×1-1/4″ RAKtherm PPRc PN 25 is a brass-threaded female adaptor (transition fitting) from RAKtherm (UAE), designed for PPR (Polypropylene Random Copolymer, often called PPRc) piping systems. It connects a 40mm PPR pipe (via socket fusion welding) to a 1-1/4 inch (approximately 32mm) female threaded connection, such as valves, faucets, pumps, or other threaded fixtures.

Description

• Type: Female Socket / Female Adaptor (threaded brass insert). The PPR body has a socket end for fusing to 40mm pipe; the other end features a 1-1/4″ female brass thread.
• Material: High-quality PPR (PP-R 80 or similar food-grade polypropylene random copolymer) with a brass threaded insert for durability and corrosion resistance. RAKtherm products are manufactured in Ras Al Khaimah, UAE.
• Key Features: Corrosion-resistant, scale-resistant, lightweight, and suitable for potable (drinking) water. It provides a secure, leak-proof transition between plastic PPR piping and metal-threaded components.
• Color: Typically green (standard for RAKtherm PPR).

This fitting is part of RAKtherm’s comprehensive PPR piping range for pressurized hot and cold water systems.

Specifications

• Size: 40mm (PPR socket) x 1-1/4″ (female BSP/NPT thread).
• Pressure Rating: PN 25 (suitable for nominal pressure up to 25 bar at 20°C; derates with higher temperatures).
• Temperature Range: Designed for continuous use up to 70°C (hot water), with short-term tolerance up to 95–100°C. Expected service life >50 years under normal conditions.
• Standards: Complies with relevant international standards for PPR systems (e.g., DIN, ISO). RAKtherm systems are certified for quality and food-grade safety.
• Applications: Hot & cold water supply, HVAC (chilled water, heating), plumbing in residential/commercial buildings, industrial fluid transport (non-aggressive chemicals).

Note: Exact weight/packing may vary slightly; similar 40mm fittings are lightweight (e.g., around 0.04–0.1 kg per piece depending on variant).

Installation

PPR fittings like this use socket fusion welding (heat fusion) for the pipe connection:

1. Preparation: Cut the 40mm PPR pipe squarely with a pipe cutter. Clean and dry the pipe end and fitting socket. Mark insertion depth.
2. Heating: Use a RAKtherm-approved welding machine set to ~260°C. Heat the pipe end (on male tool) and fitting socket (on female tool) simultaneously for the recommended time (typically 8–18 seconds for 40mm, depending on exact tool and ambient conditions).
3. Joining: Quickly insert the pipe fully into the socket without twisting. Hold in place for a few seconds.
4. Cooling: Allow cooling time (e.g., 2–4 minutes) before applying pressure. Do not disturb the joint.
5. Threaded End: Use appropriate PTFE tape or sealant on the 1-1/4″ male thread when connecting to other components. Avoid over-tightening.

General Guidelines (from RAKtherm):

• Perform pressure testing after at least 2 hours (preferably longer) post-welding.
• Account for thermal expansion in hot water lines (use clips, brackets, or expansion loops).
• Install in accordance with local codes and RAKtherm’s technical manual for support spacing, insulation, etc.

Tools Needed: PPR fusion welder with correct 40mm heads, pipe cutter, marker, etc.

Usage

• Primary Use: Transition from PPR distribution lines (40mm) to threaded devices in water supply, HVAC risers, manifolds, or appliance connections.
• Advantages: Creates a homogeneous, leak-free joint on the PPR side. Brass thread ensures compatibility and strength for mechanical connections. The system is durable, hygienic (no corrosion or scaling), and low-maintenance.
• Limitations: Not for extremely aggressive chemicals or very high-pressure steam. Follow temperature/pressure derating tables for long-term performance.
