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.

PVC pipe has a recommended operating temperature of 0 - 60° centigrade (32 - 140°F).
This 1/2" x 3/8" plain spigot to FBSP reducing bush is compatible with 1/2" PVC plain socket-ended fittings, and
3/8" BSP male threaded fittings. It is not compatible with metric PVC pressure pipes or plain fittings;
however, it is compatible with the 3/8" male threaded end of a metric plain to threaded fitting. 1/2"
pipe actually has an outside diameter of 21.4mm. 3/8" pipe actually has an outside diameter of 17.1mm.
This 1/2" plain spigot (measuring 21.4mm outer diameter) to 3/8" FBSP reducing bush will slot inside the socket end
of a 1/2" fitting to be solvent welded. 3/8" male BSP threaded fittings will thread into the female threaded
end of this reducing bush.
PVC (or PVCU) is one of the most widely used plastics in general industry. Its ease of installation,
rigidity, WRAS approval, and low price point compared to many other plastics makes it ideal for
applications such as:
- Factories and general process industries
- Swimming pools and spas
- Aquaculture, hydroponics, and aquaponics
- Agriculture and irrigation
- Water processing and treatment
In addition, PVC pipe also finds its way into many domestic applications, including:
- Salt and freshwater aquaria
- Ponds and water features
- Home pools, hot tubs, and spas
- Micro irrigation
