1 Actual pressure/temperature ranges should be confirmed based upon the specific manufacturer's fittings being utilized.

2 Some manufacturers' systems are rated to below 0°F (-18°C) and may not be rated or recommended to 250°F (121°C).

3 Temperature ranges for various gasket types and clamping systems must be confirmed with the specific gasket and clamp manufacturer.
