357-2 - Miller 357-2 8.7mm Ear Clamp (Pack of 5)

Reliable Hose Connections with Miller 357-2 Ear Clamps

maintaining the integrity of your welding equipment's internal systems is crucial for performance and safety. The Miller 357-2 Clamp Ear 8.7mm is a genuine replacement part designed specifically for Miller Electric welding power sources and cooling systems. Sold in a convenient package of 5, these clamps are essential for technicians and welders performing maintenance on gas or water lines within their machines.

Unlike traditional worm-gear clamps that can loosen over time or damage small-diameter hoses, ear clamps (often referred to as Oetiker-style clamps) provide a permanent, tamper-proof seal. Once crimped, the clamp exerts a constant force around the hose, ensuring a leak-free connection that stands up to the vibrations and thermal cycles common in industrial welding environments. This is particularly important for shielding gas lines, where even a small leak can lead to porosity in welds, or water cooling lines, where leaks can damage sensitive electronics.

The 8.7mm size is precision-engineered to fit specific hose diameters used in Miller equipment. Using the correct size clamp is vital for preventing damage to the hose barb or fitting while ensuring the hose remains securely attached under pressure. Whether you are repairing a MIG gun coolant line, replacing internal gas tubing, or refurbishing an older power source, using genuine Miller parts like the 357-2 ensures compatibility and reliability.

At Josef Gas, we recommend keeping a pack of these ear clamps in your maintenance kit. They are a small but critical component in keeping your welding operations running smoothly. Proper installation requires a pair of jaw pincers or ear clamp pliers to crimp the "ear" of the clamp, tightening the band permanently around the hose.
