1-1/2 x 1/2 in Galvanised Reducing Tee | ST4015G
Available
This AAP galvanised reducing tee is a mild steel fitting with BSP threads. It is supplied in 13 sizes, 1-1/2 x 1/2 in (40 x 15 mm) to 4 x 3 in (100 x 80 mm).
A reducing tee has a run of one size and a branch of a smaller size. This one is threaded inside (female) at all three ports. Sizes are listed as the run first, then the branch, for example 1 x 1/2. A is the length of the run, C the run outside diameter, D the branch outside diameter and E the height, as lettered on the AAP drawing.
AAP states that its steel threaded pipe fittings are made to BS EN 10241:2000 (manufacturer-stated). It is galvanised. AAP does not state the galvanising process or coating thickness for this item. AAP states that all sizes of its fittings other than unions are sample tested to 5.2 MPa (manufacturer-stated). These are test pressures, not working pressures, so confirm the pressure and temperature for your application with AIMS before you order.

A is the length of the run, C the run outside diameter, D the branch outside diameter and E the height, as lettered on the AAP drawing, in millimetres. Sizes are run first, then branch. Weights are approximate, in kilograms per piece. A dash means AIMS is not showing that figure while it is checked with AAP.
Selecting the right option
Choose the size to match your pipework. These fittings are BSP threaded, so check that your pipe or fitting is BSP and not NPT before you order. Sizes are listed as the run first, then the branch.
