Unparalleled Durability, Precision, and Long Service Life

A wide variety of pressure gauges are used for measurement purposes across industries today. Liquid-filled brass gauges are popular for their durability and precision. Brass gauge applications have significantly expanded with the rise in the use of portable equipment such as compressors, pumps, and hydraulic tools.

One hundred and seventy years ago, French engineer Eugene Bourdon invented the C-shaped hollow tube that is sealed at one end. The sealed end shifts with a rise in pressure inside the tube, and this displacement is used to measure pressure. Despite a wide range of pressure instruments that exists today, the mechanical Bourdon tube gauge remains the most common method to measure pressure.

WIKA’s model 213.40 Bourdon tube brass gauge utilizes this age-old technology in combination with a solid piece of forged brass that constitutes the socket and a liquid-filled case. The use of solid brass increases durability and minimizes leakage and damages due to misapplications.

The 213.40 was the first liquid gauge introduced to the U.S. market, in the 1960s, and WIKA continues to be the sole U.S. manufacturer of this type of solid brass gauge. Over the years, overseas importers have copied numerous models of brass gauges and introduced them to the market, but WIKA’s model 213.40 remains unparalleled in its quality, robustness, accuracy, and long service life.

WIKA’s Model 213.40 Bourdon Tube Brass Gauge

WIKA’S Bourdon tube brass gauge has a “one-piece” solid forged-brass case and socket, and its liquid filling enables it to withstand most adverse conditions, including high vibration, shock, and pulsation. Known as “The Hydraulic Gauge” in the industry, the 213.40 is used in mobile and stationary machinery, and many other heavy-duty hydraulic applications. Mechanical brass gauges are also extensively used in upstream oil applications with pressure ranges of up to 15,000 psi. WIKA’S glycerine-filled, crimped bezel brass gauges are virtually indestructible and are the standard in the Texas oil patch.

WIKA USA’s comprehensive portfolio of pressure instruments consists of several customizable process gauges, including models built to meet the demanding conditions of the oil and gas industry.
