7000 Series Ermeto Steel Flareless Tube Fitting, 0.75 Inch Tube OD Union 90 deg Elbow

Stainless steel tubing is one of the compatible options for this fitting. It also works with aluminum, hard or half copper, regular steel, and extra heavy wall tubing that can't be flared. The flareless design is actually a big part of why it covers so many tubing types, including wall thicknesses that would be tough or impossible to flare in the field.
