The pressure rating is printed on plumbing pvc pipe.
Pvc fittings pressure rating.
The chart below will illustrate the pressure derating of pvc as temperatures increase.
Pressure 73 f pressure 73 f pressure rating for pvc schedule 80 unions one of the more complex questions in the plastic pipe and fittings industry is associated with the pressure rating of fit tings used in pvc schedule 40 and pvc schedule 80 systems.
Be aware that schedule 40 pvc pipe does have a lower pressure rating therefore using schedule 40 parts on a primarily schedule 80 pipe system is not recommended.

The specifi ed derating factors for pvc or for cpvc are suit able for pipe conveying water at elevated temperatures.
Pvc conduit isn t approved to use in plumbing applications because it isn t pressure tested making the chances of leaking higher.
Schedule 40 and schedule 80 pvc pipe and fittings have identical od outer diameters and can be used interchangeably if needed.
Australian standards for pvc pressure pipes cover composition dimensions performance and marking requirements for pipes fittings and joints.
Pvc is one of the thermoplastic materials most frequently specified for a variety of products used in the pipe and fittings industry.
1 psi lb in2 6 894 8 pa n m2 1 inch 25 4 mm.
Pipes are designated by their nominal size dn and their nominal pressure rating or class at 20 c pn.
The pressure ratings given are for water non shock 73 f.
As the temperature of the pvc increases the pressure that the pvc can withstand will decrease.
Polyvinyl chloride pvc schedule 40 pressure fittings are used for potable water chilled water irrigation golf course construction and pool spa applications.
The maximum operating pressures derates with temperature.
For pvc fitting schedule 40 and pvc fittings schedule 80 the optimal temperature at which pvc can operate at the highest psi would be 73 degrees fahrenheit.
