TUPY figure numbers, and what the trade calls them

Figure numbers are how this range is ordered, and almost nobody has them memorised. This table lists every figure published on this site against its standard designation and the names it goes by on site, so an enquiry that says "reducing bush, 1in to 1/2in, galvanised" and an enquiry that says "figure 241" can both be priced without a phone call.

Why the same fitting has four names

A 90 degree elbow is a knee in one market, an ell in another and a bend in a third. A socket is a coupling in American practice and a sleeve to plenty of fitters. A bush is a reducer, and a reducing socket is also a reducing coupling. None of this is wrong - it is trade vocabulary that travelled with the people who taught it, and in a region staffed from a dozen countries all of it is in use on the same site.

The figure number is the fixed point. It does not change with the language of the person ordering, and it is what appears on the casting, the carton and the invoice.

How to read the designation column

Most figures carry a designation from the standards that govern threaded malleable iron fittings: EN 10242 and ISO 49 for the threads and the shapes, with ABNT NBR as the Brazilian equivalent. Where a specific type code is published for the figure - U11 for the iron conical seat union, E2 for the side outlet elbow, P4 for the threaded flange - it is shown as published.

Where the column shows the standard without a type code, the figure is covered by that standard but is ordered by figure number rather than by designation. Nothing has been inferred to fill a gap.

Using this to check a competitor's list

A takeoff written against another manufacturer usually names shapes rather than that maker's codes: elbow, tee, socket, bush, union, cross. Read down the trade names column, take the figure number, and the sizes and weights are on the linked page. Anything the list calls for that is not here is worth sending anyway - the range is wider than the figures published on this site.

Frequently asked questions

What is figure 90?

The 90 degree equal elbow - also called a bend, a knee or an ell. Figure 90R is the reducing version and figure 92 is the male/female street elbow.

What is the difference between figure 240 and figure 241?

Figure 240 is a reducing socket, female at both ends. Figure 241 is a bush - male on the outside, female inside - which screws into a larger fitting to reduce it.

Which union should I use, 330, 340 or 342?

Figure 340 is the iron conical seat union, the general purpose choice; 330 has a flat seat; 342 has a brass seat and is the one usually specified for gas. All three are in the table with their designations.

Are all of these held in Dubai?

The range is held in stock in Dubai in both galvanised and black, 1/4in to 6in. Send the figures and sizes and availability is confirmed with the quotation.

Do the figure numbers change between galvanised and black?

No. The figure identifies the shape; the finish is a separate column on the order.

Need this for a project?

Send the figures, sizes and quantities and it will be quoted from stock in Dubai or direct from Brazil, whichever lands cheaper.
