Choosing and fitting
Parts of this type are selected by matching the tube outer diameter (here 4 mm) and the thread type and size of the mating port. Before ordering, verify the fitting against the original installation to ensure compatibility. During installation, cut the tube end square and deburr it, and always fit a new ferrule; reusing an old one risks leakage.
Signs of failure
Items of this kind typically fail by developing leaks due to worn or reused ferrules, overtightening, or improper tube preparation. Symptoms include gas odor, hissing sounds, or a drop in pressure in the pilot line. Check the fitting for visible damage, ensure the ferrule is new, and verify the tube is properly seated.
