45° Lateral Tee — TUPY Brazil fittings

The TUPY Brazil 45° lateral tee (figure 165) takes the branch off at 45°, in the direction of flow. That angle makes the pressure loss and the turbulence at the branch far lower than with a 90° tee.

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.

About the 45° Lateral Tee

In a plain tee the branch flow enters the main line at a right angle; the two streams collide, which creates turbulence and pressure loss. In a 45° lateral tee the branch runs much closer to the line of the main flow, and that has three practical effects: less pressure loss, less settlement and blockage on lines carrying suspended solids, and more even mixing.

For that reason the TUPY technical catalogue recommends an angled branch rather than a 90° tee where hot and cold water are mixed; mixing in a plain tee can push flow back into the opposite line.

The material is blackheart malleable cast iron to grade JMB 350-10, produced hot-dip galvanised and black. Sizes run from 1/2 to 4in.

Frequently asked questions about the 45° Lateral Tee

In which sizes is the TUPY Brazil 45° Lateral Tee made?

The TUPY Brazil 45° Lateral Tee is made in 9 sizes, from 1/2" to 4". 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.

How much does one TUPY 45° Lateral Tee weigh?

The weight depends on the size: the 1" size, for example, weighs 0.330 kg galvanised and 0.325 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.

Is the thread on the TUPY 45° Lateral Tee BSP or NPT?

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.

What is the maximum working pressure and temperature of TUPY fittings?

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.

To which standards is the TUPY 45° Lateral Tee manufactured?

The TUPY 45° Lateral Tee is manufactured to ISO/EN/NBR B1/45°. 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.

How can you tell a genuine TUPY Brazil 45° Lateral Tee?

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.

How do I get a quotation for the 45° Lateral Tee?
