Product Description
OR3 to OR4 Straight Tube Fitting | Refrigeration Hose & Component Connector
Product Overview
This OR3 to OR4 straight tube is a professional transition fitting for refrigeration and cold chain systems. It acts as a critical bridge between OR3 and OR4 size hoses/pipelines and core rigid components (compressors, oil separators, receivers), ensuring stable refrigerant flow and leak-proof performance in commercial and transport refrigeration units.
Key Features
  • Size Transition Design: Converts between OR3 and OR4 hose/pipeline sizes, enabling flexible system layout and component compatibility
  • Straight Structure: Ideal for linear pipeline routing, minimizing flow resistance and pressure loss
  • High-Strength Zinc-Plated Steel: Resists corrosion, vibration, and wear, suitable for long-term operation in harsh refrigeration environments
  • Dual O-Ring Sealing: Prevents refrigerant leakage under high-pressure and variable-temperature conditions
  • Precision Machining: Smooth inner bore ensures efficient refrigerant flow and system performance
  • Compact Design: Saves installation space, suitable for narrow engine compartments and refrigeration units
