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 40mm x 1 1/4" plain to threaded FBSP union is compatible with 40mm PVC pressure pipe and spigot fittings, and
1 1/4" BSP male threaded fittings. The solvent weld end is not compatible with inch PVC pressure pipe or spigot
fittings. The BSP female threaded end is compatible with BSP male threads on both inch and metric fittings. 1 1/4" pipe
actually has an outside diameter of 42.2mm.
40mm pipes or spigot fittings (measuring 40mm outer diameter) will slot inside the plain end of this
union to be solvent welded. 1 1/4" male BSP threaded fittings will thread into the female threaded
end of this union.
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
