The fittings have a general conformance with dimensional standard MIL-DTL-52618-E; the flanges and flanged fittings with dimensional standard ANSI B16.1. Fittings are randomly tested at 120 pounds of air pressure under water, for a normal surface condition rating of 150 pounds of pressure. Extra-heavy couplings cannot be tested or certified for pressure rating. Individual fittings are not marked with alloy or pressure data. Fittings are not anodized.
