Durable brass and stainless steel construction, serviced without leaving the machine

The 107 Series Rotary Union (EMS — Easy Maintenance Series) features a durable brass and stainless steel construction with replaceable rotary and stationary seals. Designed for easy maintenance, it delivers reliable sealing, reduced downtime, and long-lasting performance across water, gas, hot oil, and steam applications from 1″ to 6″.

Key features

Eight features built around one design brief: fast, in-place seal replacement

The 107 Series brings together everyday reliability features with the EMS maintenance advantage that sets it apart from a standard rotary union.

Single & dual flow condition

Available for different fluid transfer applications, whether a single slow or dual flow are required.

Radial & axial, threaded or flanged connection

Provides flexible connection options for different machine configurations.

Brass head & stainless steel housing

Made from a brass head and stainless steel housing combination for reliable and durable performance.

107 EMS — easy maintenance service

Seal kit can be changed without dismantling the rotary union from the machine, making maintenance quick and easy.

Springs located outside the flow area

Springs are positioned outside the flow area to avoid pressure drops and turbulence.

Low noise & vibration

Reduced turbulence helps minimize noise and vibrations during operation.

Seal combinations for harsh water applications

Different seal combinations are available for demanding and harsh water applications.

Replaceable rotary & stationary seals

Both rotary and stationary seals are replaceable for easy maintenance and extended service life.

EMS — easy maintenance service: why it matters

Seal kit can be changed without dismantling the rotary union from the machine, making maintenance quick and easy.

On a union sized 1″ to 6″, dismantling the whole assembly for a routine seal change is a significant chunk of planned — or unplanned — downtime. EMS was designed to remove that step entirely.

Standard rotary union maintenance

The whole union comes off the machine

In a conventional rotary union, replacing a worn seal means disconnecting the union from its pipework and mounting, removing it from the machine, and reassembling it on a bench before reinstalling — a job that takes the connected line out of service for longer than the seal change itself requires.

107 EMS Series

The seal kit comes out, the union stays put

The seal kit can be changed without dismantling the rotary union from the machine, making maintenance quick and easy. Replaceable rotary and stationary seals mean the union itself never has to leave its mounting — reducing downtime and keeping the connected pipework and machine interface undisturbed.

Construction & connection flexibility

A brass and stainless steel body, fitted the way your machine needs it

Beyond the EMS maintenance advantage, the 107 Series is built to drop into a wide range of machine configurations without forcing a redesign of the connection interface.

Brass head & stainless steel housing

Made from a brass head and stainless steel housing combination for reliable and durable performance across water, gas, hot oil service.

Radial & axial, threaded or flanged connection

Provides flexible connection options for different machine configurations, to ISO 228 (NPT / Metric) thread standard, with a flange-type quick release nipple.

Replaceable rotary & stationary seals

Both rotary and stationary seals are replaceable for easy maintenance and extended service life, with seal combinations available for demanding and harsh water applications.

Operating conditions

Rated across water, gas, hot oil, service, from 1″ to 6″

Provides flexible connection options for different machine configurations, all to ISO 228 (NPT / Metric) thread standard.

⇆

Radial connection

Threaded or flanged radial connection to suit machine layouts where the pipework enters perpendicular to the rotor axis.

⇅

Axial connection

Threaded or flanged axial connection for in-line installations along the rotor axis.

□

Flanged end fitting

A flange-type quick release nipple is available for fast disconnection during maintenance or machine changeover.

Where the 107 fits

Wherever a seal change shouldn't mean pulling the union off the machine

The EMS maintenance advantage, combined with a size range up to 6″ and a 210°C temperature ceiling, makes the 107 Series a practical fit across a broad span of industrial fluid transfer duty.

Water & gas transfer

General industrial water and gas circuits running up to 15 bar, where EMS keeps routine seal maintenance from becoming a full union changeover.

Hot oil & steam applications

Circuits running up to 210°C, where the brass and stainless steel construction holds up under sustained thermal service.

Harsh water applications

Demanding water conditions where a dedicated seal combination is specified to match the actual fluid quality in service.

Larger-bore industrial machinery

Sizes from 1″ to 6″ where downtime during a seal change is costly enough that in-place maintenance is a genuine operational advantage.
