Aluminum Versus Stainless Steel
The Parker Hannifin Corporation (Columbus, OH) has introduced a new line of SAE aluminum tube fittings that are approximately 65 percent lighter than equivalent steel and stainless steel fittings, according to the company. The aluminum fittings can reduce the costs of converting a system from steel or stainless steel because no component redesign is necessary. More features include:
- Temperature rating ranges from -40° to 400°F, depending on the seal material.
- The Trap-Seal technology which uses a trapezoidal-shaped seal to prevent “pop out” associated with round-shape O-rings.
- No exposed threads between the locknut and backup washer.
