Material: Brass Key benefits Good mechanical properties: Brass joints withstand pressure and tensile forces, offer strong toughness, are not easy to break, and remain stable during refrigerator operation. Stable temperature performance: Brass joints maintain good performance in temperature environments and do not degrade significantly due to heat, adapting to elevated temperatures that can occur during operation. Good sealing: With reasonable design and proper installation, brass joints seal effectively, prevent refrigerant leakage, support normal refrigeration system operation, and help reduce energy consumption. Good compatibility: Brass joints work with common refrigeration materials (such as copper pipes, steel, and other typical system components) to ensure stable operation. Use scenarios Domestic refrigerator or upgrade: worn joints to restore seal integrity and efficiency. Commercial refrigeration and cold storage: reliable joints for heavyuse environments, supporting longterm performance. System retrofits and material transitions: connect different pipe materials (eg, copper to steel) to facilitate upgrades and maintenance.
