The TUPY Brazil return bend, 180° (figure 60) turns the flow back on itself in a single piece. It replaces two 90° elbows and a nipple: shorter, lighter, and with two threaded joints fewer.

| Size range | 1/2" – 2" |
| Finish | Galvanised and black |
| Thread | BSP (ISO 7-1) |

The size range summarises this figure's table and does not guarantee stock in every size. TUPYBSP working pressure is 25 bar from −20 to +120 °C; consult the catalogue pressure–temperature table outside that range. Hydrostatic test values are not working pressures; the catalogue specifies a separate 37.5 bar test value for joints. Check the product-family catalogue and the required figure and size approvals before selection.
These marks relate to TUPY product-line standards and approvals. Scope varies by figure, size and application; confirm the current catalogue and figure-specific listing before specification.

In plant rooms and tight networks the flow often has to turn through 180° in a short distance — on a radiator flow and return, or between parallel runs. The usual answer is two 90° elbows screwed onto a nipple. That is three components and four threads; it takes up space and it raises the chance of a leak.
The figure 60 return bend does the same job in one piece. The TUPY technical catalogue explicitly recommends a 180° return bend in place of the elbow-and-nipple combination.
It is cast in blackheart malleable cast iron to grade JMB 350-10 and supplied in two finishes, hot-dip galvanised and black. Sizes run from 1/2 to 2in.
Dimensions and weights by size: ½in code 1229004, a = 38, z = 30 mm; ¾in code 1229006, a = 50, z = 36; 1in code 1229007, a = 64, z = 45; 1¼in code 1229008, a = 76, z = 53; 1½in code 1229009, a = 89, z = 60; and 2in code 1229010, a = 102, z = 70 mm. Galvanised weight runs from 0.155 to 1.499 kg.
The TUPY Brazil Return Bend (180°) is made in 6 sizes, from 1/2" to 2". The full list of sizes, with the dimensions in millimetres and the weight of each piece, is in the dimensions and weights table on this page.
The weight depends on the size: the 1" size, for example, weighs 0.465 kg galvanised and 0.455 kg black. The weights of every size are taken from the official TUPY catalogue and are listed in the table on this page, so they can be used to work out shipping weight and freight cost.
TUPYBSP fittings are threaded to BSP in accordance with ISO 7-1; the male thread is tapered and the seal is made on the thread itself. BSP is not interchangeable with NPT, and screwing the two together will leak. TUPY also produces a separate NPT line, which is covered in the downloads section.
According to TUPY's technical catalogue, the working pressure of TUPYBSP fittings is 25 bar between −20 °C and +120 °C. For temperatures outside that interval, use the catalogue pressure-temperature table and confirm suitability for the application. The catalogue lists hydrostatic design-test pressures of 100 bar for other fittings from 1/4 in to 4 in, 64 bar for 5 in and 6 in, and 37.5 bar for joints. These are test values, not working-pressure ratings. Confirm the applicable fitting, temperature range and project requirements before selection.
The TUPY Return Bend (180°) is manufactured to ABNT NBR BK1. TUPY malleable cast iron fittings are built to ISO 49, EN 10242 and ABNT NBR 6943, and their threads follow ISO 7-1. Check the current figure- and size-specific listing before relying on an approval.
Where dimensions permit, genuine TUPY fittings carry cast markings such as the factory mark and nominal size. Check the figure-specific catalogue and packaging as well. The threads are clean and free of burrs, and the galvanised coating is even. The surest check is to weigh the piece and compare it with the weight table on this page; counterfeit pieces usually come out lighter than the official catalogue weight.
