The TUPYPRES system changes the way pipe is joined. Instead of threading or welding, the pipe goes into the fitting with a plain cut end and the joint is pulled up tight and watertight in seconds simply by tightening the nut — hand-tight first, then with an ordinary wrench. There is no press machine and no special tool.
That removes the two main sources of error on site. A badly cut thread or an incomplete seal no longer applies, because there is no thread. No welding is needed either, so hot work is taken out of the building — a decisive advantage in occupied buildings and in areas where naked flame is not permitted.
Speed is the second difference. What takes minutes with threading is done here in seconds; on a large project that difference turns directly into programme time and installation cost.
The TUPYPRES elbow is supplied as figure 1907 and, like the rest of the TUPYPRES range, is FM Approved, UL Listed and DVGW certified. Sizes 1/2in to 2 1/2in.
The TUPYPRES Elbow is made in 2 sizes, from 2" to 2.1/2". 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 2.1/2" size, for example, weighs 3.056 kg. 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.
An ordinary wrench. No press machine and no special tool is required. Cut the pipe square, deburr it, push it into the fitting up to the marked depth, then tighten the nut by hand and finish with a wrench to the torque and number of turns given in the TUPYPRES catalogue. If a joint is taken apart, replace the ring set before making it up again.
TUPYPRES is a mechanical compression joint. The pipe goes into the fitting and the nut is tightened — no threading, no welding, no flame and no press machine. A ring set already assembled inside the fitting (rubber sealing ring, compression ring and locking ring) makes the joint tight as the nut is drawn up. Installation is far quicker than threading and calls for less skill; the main uses are fire protection, water, gas and compressed air networks.
According to the TUPYPRES catalogue, on steel pipe: water up to 16 bar at 80 °C, liquid fuel up to 16 bar at 80 °C, compressed air up to 10 bar at 80 °C and gas up to 10 bar at 70 °C. Lower figures apply on PE80 and PE100 polyethylene pipe, and the system is not recommended for compressed air on polyethylene.
The TUPYPRES system can be installed on steel pipe to NBR 5580 and NBR 5590 (equivalent to EN 10255 and DIN 2440/2441) and on PE80 and PE100 polyethylene pipe. A transition fitting is also available for joining steel pipe to polyethylene pipe.
On the body of every genuine TUPY fitting the factory mark, the figure number and the size are raised in the casting, not etched or printed. 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.
