** The Pressure ratings shown are for water, non-shock, @ 73°F with plain end pipe. Threaded pipe requires a 50% reduction in the pressure ratings stated. Appropriate temperature de-rating factors must be applied to determine the maximum allowable pressure when working at elevated temperatures greater than 73°F.
