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