Sale price£11.51


Flange Assembly Plain x BSP


The full-face flange assembly enables PVC pipework to be readily joined and dismantled. This can provide facility for blanking-off pipework and for the installation of butterfly and swing-check valves.

Components are supplied loose for self-assembly. The assembly comprises:-

  • 1 x solvent weld full face flange
  • 1 x BSP full-face flange
  • 1 x full-face gasket
  • BZP bolt sets to fit each bolt hole.

Bolt sets are sized to suit flange to flange connection. Where a valve is to be installed between flanges it will be necessary to supply longer bolt sets and an additional gasket.


Imperial solvent weld PVC fittings are generally manufactured in accordance with EN1452-3. 

Threaded PVC fittings are generally manufactured in accordance with BS21, DIN2999, ISO7.

All fittings have WRAS approval and are suitable for use with potable drinking water applications.

Pressure Rating

PVC solvent weld fittings (sizes 1/2" to 8") have a pressure rating of 15 bar (215 psi) at 20oC.

PVC threaded fittings (1/2" to 4") have a pressure rating of 12 bar (170 psi) at 20oC

As temperature increases the pressure rating is reduced.  PVC systems should not be used where temperatures exceed 60oC.

Flange Sizing

The number and diameter of holes together with the PCD determines the flange size and pattern.  The PCD (Pitch Circle Diameter) is the measurement from the centre of one bolt hole, across the centre of the flange, to the centre of the opposite hole.

The table below details the specification for PN10/16.  We can also supply Table D/E if required.
