| Size range | 1/2" – 6" |
| 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.

The cap, unlike the plug, has an internal thread and screws over the end of a pipe or a nipple. Both close off the run, but they are used in different places: the plug goes inside a female port, the cap goes over a male one.
At the top of risers, on spare pipe ends and at the end points of fire protection networks, the cap is the usual choice, because fitting it over the pipe end is simpler than adding a female fitting and then a plug.
Like the plug, the cap always carries the full line pressure. The hexagonal body allows it to be tightened with a spanner and torqued enough for a reliable seal.
The TUPY cap is supplied as figure 300: malleable cast iron, BSP thread to EN 10242 and ISO 49, galvanised and black.
The TUPY Brazil Cap is made in 10 sizes, from 1/2" to 6". 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 0.154 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 Cap 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.
