AAP Black Steel Cross 1-1/2" (40mm) Female BSP - SCR40

This AAP cross is a black mild steel pipe fitting with female BSP threads at all four ports. A cross has four ports of the same size set at right angles, so a threaded pipe run can branch in two directions from one point.

It is supplied in 8 sizes, 1/4" (8mm) to 2" (50mm). AAP lists it for industrial, steam, pumping, compressed air and water lines. It is the black (uncoated) version of the galvanised AAP cross; the dimension A in the size table is the overall length across the cross.

Key specifications

Choosing the right option

Choose the size to match your pipework. These fittings are BSP threaded, so check that your pipe is BSP and not NPT before you order. For a corrosion-resistant finish see the AAP Galvanised Steel Cross.

Using it

Clean the threads, apply a suitable thread sealant or tape, and tighten with the correct size pipe wrench.

Storage and handling

Black steel has no protective coating. Store indoors and dry to limit surface rust before installation.

Limits and safety

Black steel has no corrosion protection. Check the pressure and temperature rating with AAP before use on steam or compressed air lines, and give us a call if you are unsure which finish suits the job.
