LP Copper Elbow | 1-1/8″ x 90 Degree | Solder/ODF Connection
Product Description: The LP 1-1/8″ (28.6mm) 90-degree elbow is manufactured from premium ASTM-standard copper, ensuring a consistent wall thickness and excellent brazing characteristics. In the UAE’s large-scale refrigeration sector—such as supermarket racks and walk-in cold stores in Dubai—this 1-1/8″ size is commonly used for main suction lines. The “short radius” or “long radius” design (depending on specific piping needs) ensures a smooth refrigerant flow with minimal pressure drop. Its ODF (Solder) ends are precision-machined to provide a perfect slip-fit over 1-1/8″ copper tubing, facilitating a high-strength, leak-proof joint when brazed using silver solder or copper-phosphorus rods.
Key Features & Benefits:
- Pure Deoxidized Copper: Made from 99.9% pure copper, offering superior thermal conductivity and resistance to the corrosive humidity of the Gulf region.
- Precision Sizing: The ODF connections are sized to tight tolerances, ensuring a snug fit for efficient capillary action during the brazing process.
- High-Pressure Capability: Engineered to handle the high operating pressures of modern refrigerants like R404A and R410A.
- Smooth Internal Finish: Minimizes turbulence and oil trapping, which is essential for maintaining compressor health in large UAE systems.
- Compliance: Manufactured to meet international HVAC standards for plumbing and refrigeration fittings.

FAQs:
- Q: Is this elbow suitable for the high-side discharge line?
- A: Yes, the 1-1/8″ copper elbow is rated for both high-side and low-side applications, provided the brazing is performed to professional standards.
- Q: Do I need a specific flux for brazing this LP fitting in the UAE?
- A: When brazing copper-to-copper with phosphorus-silver rods (like Harris 0 or 5), flux is usually not required. However, for copper-to-brass, a suitable flux should be used.
- Q: Can this be used for medical gas installations in Abu Dhabi?
- A: This fitting is designed for HVAC/R. For medical gas, ensure the fitting is degreased and capped to meet specific healthcare oxygen-clean standards.
