Leku-Ona now offers the new range of Faster® Ultra High Pressure (UHP) quick hydraulic couplings The latest models UHP 100 and UHP 150 have applications in the world of industry and high pressure tools

For more than 30 years, Leku-Ona has been the exclusive distributor in Spain and Portugal of products by FASTER®, a company recognised worldwide for its state-of-the-art and reliable couplings and quick connectors.

One of their latest innovations, launched at the most recent Hannover Messe trade fair, is a new range of hydraulic quick couplings under the name of Ultra High Pressure UHP 100 and UHP 150, which is a result of the strategic decision by the Italian brand to invest in R&D in order to offer top quality products aimed at the industrial sector and high pressure tools.

This has led to the new UHP couplings having numerous technological features that make them extremely reliable and easy to use, ensuring exceptional safety for the operators in all aspects of their work.

Faster has replaced radial balls with a Faster patented new technology. Our sector latching system prevents damages on the male groove caused by radial balls in situations of pressure peaks. We have introduced as standard a screw-on safety sleeve with a double visual check with two colours (red and green). This system indicates the complete and correct connection of the two halves.

Moreover, given the extreme working condition of their application (industrial cylinders, rescue tools, lifting equipments..), we have them tested and certified 100%. 

The special laser marking on each single couplings guarantees an excellent legibility of the batch number.

On Faster website it is possible to dowload a certificate that testify that each batch has been tested and approved according to Faster quality standards. 

First delivery is expected in May. Meanwhile, the new part numbers for UHP 100 and UHP 150 can already be ordered at Leku-Ona.

In the download section of FASTER portal, you can download the instruction and safety guidelines, with helpful information for a safe and correct use.

Leku-Ona ran in the 10th Adegi Corporate Race The team from Leku-Ona Group competed in the men’s category and completed the 8.5 kilometres in 42:06 minutes.

On May 7th a team of employees from Leku-Ona Global Solutions took part in the 10th Corporate Race organised by Adegi in San Sebastián. 

Participants in the 8.5 kilometre race along the entire coastline of the city enjoyed running next to the sea and the great atmosphere during the event.

Some 530 teams competed this year — a new record, with 60 more teams than at the last event. The race has been getting stronger year after year, and around 2,200 people took part this time.
Employees from Caf, JMA Alejandro Altuna and Schaeffler won the men’s category, whilst the mixed category was won by Salto Systems, Fagor Arrasate and IMQ campeones. The female race was won by the Clinica La Asunción, Eroski and Kutxabank.

Congratulations to all those who took part!

Basic considerations when choosing a hydraulic or pneumatic pressure gauge Selecting the ideal pressure gauge for each installation will depend on the type of assembly, material and ranges.

Measuring the operating parameters of a circuit is essential to be able to verify whether it lies in the correct range or to detect and identify the reasons why it may not be working properly.

A pressure gauge is the instrument used for measuring fluid pressures in both hydraulic and pneumatic circuits, and generally determines the difference in pressure between the fluid and the local pressure.

Given that most pressure gauges measure the difference between the pressure of the liquid and the local atmospheric pressure, the latter must be added to the value indicated by the pressure gauge to find the absolute pressure. A negative reading on the gauge is caused by a partial vacuum.

Pressure gauges are used to measure gauge pressures that vary between 0–1 kg/cm2 and between 0–10,000 Kg/cm2, and to measure vacuum. The gauge accuracy may be between 0.1 and 2% of full scale, depending on the material, design and precision of the parts.

Pressure gauges are usually installed on pumps, portable compressors, industrial equipment, hydraulic and pneumatic systems, instrumentation and pressurised containers, and various aspects must therefore be considered when selecting a gauge:


The different types of pressure gauges available come in a series of copper alloys, stainless steels and nichrome. Copper alloys give better results in some respects, but stainless steels offer greater resistance to corrosion.

Nickel iron alloys are also used. Their coefficient of expansion is very small, meaning that the pressure reading is not affected by the temperature of the instrument.

Mechanical and pneumatic instruments have an accuracy of 0.5% of the scale.


Hydraulic pressure gauges have diameters of 63 and 100 mm, while pneumatic gauges come in diameters of 40, 50 and 63 mm.


Pressure gauges can be vertical or back mounted, and can also be designed for mounting on a panel using a frontal ring or flange. Each of these details affects the selection of the ideal gauge.


At Leku-Ona Global Solutions we can manufacture the pressure gauge casing in plastic, black painted steel or stainless steel. Hydraulic pressure gauges are usually filled with glycerine while pneumatic gauges are usually dry.

The face is manufactured from glass or polycarbonate and the tubular spring (inside) is brass.

Ranges or scales in hydraulic pressure gauges

Hydraulic pressure gauges have scales from 0–0.6 bar to 0–1000 bar (depending on the model), while the ranges for pneumatic gauges are 0-1 bar and 0-20 bar.

For vacuum gauges, the scales for vacuum, vacuum/pressure or pressure are usually -1-0 bar or -1-3 bar. Precision class (3-2-3%) 1 or 1.6. Manufactured in accordance with ASME / ANSI 40-1, B.1985.

Ranges to 30”Hg/6000 psi.


The standard threaded tube is made from brass but Leku-Ona Global Solutions also offers plastic and rustproof (on request). Standard connectors come with male fittings GAS 1/8″, 1/4″,1/2 “, depending on the model (others on request).

The gauge can be mounted to a minimex hose, tubing joint, instant fitting or valve.

Gauge protection

Pressure gauges are protected using a rubber protector or an inline mounted valve, 90º valve, with switch or panel-mounted switch.










To complete the model number, add the total value of the pressure scale to identify the initial design. .
