The Ranco 1290132-B48 is a professional-grade 48-inch refrigeration hose engineered specifically for critical pressure management in commercial HVACR systems. Designed with straight x straight (STR x STR) 1/4" female flare (7/16-20) connections, this heavy-duty component serves as a robust alternative to standard copper capillary tubing. Experienced technicians utilize this hose to prevent common system failures caused by work hardening and compressor vibration, which frequently lead to fatigue in traditional hard-line setups. Constructed with high-integrity Teflon (PTFE) tubing and reinforced with a 304 braided stainless steel outer jacket, the 1290132-B48 handles extreme field conditions. It maintains structural integrity under a maximum operating pressure of 3,000 PSI and features a significant 12,000 PSI minimum burst pressure. This vibration-resistant hose is compatible with a wide range of refrigerants, including R-410A, R-404A, and R-134a, making it an essential part for high-pressure cut-out controls and commercial refrigeration pressure monitoring. Its flexibility, with a 2-inch minimum bend radius, simplifies installation in tight equipment housings where rigid tubing is prone to snapping. Key Benefits: Eliminates Capillary Failure: Replaces fragile copper lines to stop leaks caused by extreme vibration and mechanical fatigue. High Pressure Rating: Safely operates in high-side applications with a 3,000 PSI working limit and 12,000 PSI burst ceiling. Superior Chemical Resistance: Teflon core ensures compatibility with all standard synthetic and mineral oils and modern refrigerants. Stainless Steel Protection: Braided 304 stainless steel prevents kinking and provides a durable barrier against environmental corrosion. Vacuum Rated: Suitable for deep system evacuation down to 28 in/Hg. Common Questions: Can this hose be used for water distribution? No, this stainless steel braided hose is specifically engineered for refrigerant and oil transfer; do not use it for water service. What connection size does this use? It features standard 1/4" SAE female flare (7/16-20 thread) fittings on both ends for direct installation to controls and service ports. Is this hose flexible enough for tight radius bends? Yes, the hose is designed with a 2-inch minimum bend radius, making it ideal for compact compressor compartments.
