Leaks in coils made from aluminum are commonly repaired with ___________.

Aluminum coils, often used in refrigeration and HVAC systems, can develop leaks due to corrosion or mechanical damage. The most effective method for repairing these aluminum coils is by using epoxy. Epoxy is a versatile adhesive that creates a strong bond and fills gaps effectively, making it suitable for sealing leaks in aluminum without compromising the integrity of the coil. Epoxies are also resistant to the temperatures and pressures typically found in refrigeration systems, ensuring a durable repair.

Other methods, such as welding and soldering, are not ideal for aluminum since these processes can alter the material properties of the aluminum and may not create a watertight seal. Sealants, while useful, often do not provide the structural integrity or durability required for a long-term fix in high-pressure environments. This makes epoxy the preferred choice for reliably repairing leaks in aluminum coils.
