SAE aluminum tube fittings are approximately 65% lighter than equivalent steel and stainless steel fittings. The lifhter fittings help save fuel, freight and shipping costs. The cost of converting a system from steel or stainless steel is also minimal, since no component redesign is necessay. The fittings are manufactured to SAE TFD Aluminum Fittingstured J514 dimensions for 37° flare fittings and SAE J1453 dimensions for O-ring face seal fittings.
The connectors are appropriate when weight reduction and/or corrosion resistance are essential. The maximum working pressure rating for the fittings is approximately 50% of steel fittings, while the temperature rating ranges from -40°F to 400°F depending on the seal material.
The fittings also feature a trapezoidal-shape seal, which prevents “pop out” associated with round-shape O-rings and further reduces the risk of seal damage and leakage. The manufacturer also offers robust port studs that keep threads unexposed between the locknut and backup washer, and so the potential for washer damage and leaks is eliminated.
