The pressure rating of PVC pipe and fittings reduces with increasing temperature. To calculate the actual pressure rating of the product at each temperature, the noted pressure rating must be multiplied by the 'de-rating multiple', as explained on our PVC category page.

The temperature derating table of this fitting is as follows:

Temperature (°C)	Pressure Rating (bar)
20	15
30	12
40	8.7
50	5.9
60	3.3

PVC pipe has a recommended operating temperature of 0 - 60° centigrade (32 - 140°F).

This 4" x 3" plain reducing socket is compatible with 4" PVC pressure pipe and spigot fittings, and 3" PVC pressure pipe and spigot fittings. It is not compatible with metric PVC pressure pipes or fittings. 4" pipe actually has an outside diameter of 114.3mm and 3" pipe actually has an outside diameter of 88.9mm.

4" pipe or spigot fittings (measuring 114.3mm outer diameter) will slot inside the 4" end of this reducing socket. 3" pipe or spigot fittings (measuring 88.9mm outer diameter) will slot inside the 3" end of this reducing socket.
