All Aqua Environment components are rated for 6,000 PSI (414 BAR) and are made from gold anodized 6061 T-6 aluminum.  Since they're designed for use in rated breathing air and commercial diving applications they meet the highest standards of manufacture, quality control, and durability.  What this means to you in the field is this stuff is tested and it's tough.  As long as you supply clean, dry air to these components they'll work as long and hard as you do.
