The TUPY Brazil hexagonal cap (figure 300) closes the end of a threaded pipe. What separates it from a plain cap is the hexagonal body, which makes it simple and safe to tighten with a spanner.
| Figure number | 300 |
| 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.

To close the end of a line, the cap is screwed onto the male thread of the pipe. A round cap is awkward to grip with a pipe wrench and the body can be damaged in the process; the hexagonal body solves that and allows a controlled torque to be applied with an open-ended or ring spanner.
It is used at the end of branches left for future extension, for line testing, and at drain points.
Sizes run from 1/2 to 6in. Sample dimensions: ½in code 1241004, a = 23 mm, galvanised weight 0.059 kg; 2in code 1241010, a = 38, weight 0.436; 4in code 1241014, a = 56, weight 1.862; and 6in code 1241016, a = 63 mm, weight 3.715 kg.
The material is blackheart malleable cast iron to grade JMB 350-10, finished hot-dip galvanised or black.
The TUPY Brazil Hexagonal 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 Hexagonal Cap is manufactured to ISO/EN/NBR T1. 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.
