Equal Tee x 90^o Branch

Description

Plain tees with 90^o branch are designed to join three pieces of pipe together in a tee (branch at 90^o) configuration with the use of solvent weld cement.  No special tools are required.

Pressure Rating

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

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

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

Sizing - Solvent Weld Pipe & Fittings

Imperial (inch) PVC pipe and fittings sizing is not straightforward. They are sized by their nominal bore or approximate inside diameter.

The following table details pipe outside diameters (o.d.) for each imperial size.  The inside diameter (i.d.) of the socket end of the corresponding fitting will be the same as the outside diameter of the pipe.  

Pipe Size 1/2" 3/4" 1" 1 1/4" 1 1/2" 2" 2 1/2" 3" 4" Outside Dia mm 21.4 26.7 33.6 42.2 48.3 60.3 75.2 88.9 114.3

 

Sizing - BSP Threads

The following table details approximate thread diameters for male BSP threads.

Nom Pipe Size	1/2"	3/4"	1"	1 1/4"	1 1/2"	2"	2 1/2"	3"	4"
Thread Dia mm	21.0	26.4	33.2	41.9	47.8	59.6	75.2	87.9	113.0
