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.

The plug is a piece with an external thread that screws into a female port to close the run. It is used on branches that are not in service yet but have to be left for future extension, and at drain and pressure-test points.
The important point about a plug is that it is permanently under the full line pressure and, unlike other fittings, has no path behind it for the pressure to escape. If the thread or the body is weak, it is the first place to show itself on a pressure test.
The body is made hexagonal or slotted so that it can be tightened firmly with a spanner. The TUPY plug is supplied as figure 290, in malleable cast iron with a BSP thread to EN 10242.
It is available galvanised and black.
The TUPY Brazil Plug is made in 10 sizes, from 1/4" to 3". 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 0.152 kg galvanised and 0.140 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.
The figure 290 plug is male threaded and screws into the female end of a pipe or fitting. The figure 300 cap is female threaded and fits over the male end of a pipe. Both blank off the end of a line, and the choice between them depends only on which thread has to be closed.
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 Plug is manufactured to EN 10242 / ISO 49. 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.
