The 105 Series is an economical solution featuring a cast stainless steel housing and stainless steel internal components. Designed for general-purpose industrial applications, it offers reliable sealing, durable construction, and dependable performance across water, gas, hot oil, and high abrasive chemical circuits.
The 105 Series brings together a straightforward set of features aimed squarely at reliability and ease of maintenance.
Available for different fluid transfer applications, whether a single circuit or two independent flow paths are required.
Housing and rotor are made from casted stainless steel material for strength and durability.
Robust self-supported design for reliable operation without the need for an external mounting bracket.
Springs are positioned outside the flow area to avoid pressure drops and turbulence.
Reduced turbulence helps minimize noise and vibrations during operation.
Different seal combinations are available to suit various operating conditions.
Both rotary and stationary seals are replaceable for easy maintenance and longer service life.
Where the seal springs sit relative to the fluid stream has a direct, measurable effect on noise, vibration, and pressure loss across the union.
In many rotary union designs, the compression springs that load the seal faces sit directly in the fluid stream. At higher flow velocities this generates turbulence around the spring coils, creating noise, vibration, and a measurable pressure drop across the circuit.
The 105 Series positions its springs outside the flow area entirely, avoiding pressure drops and turbulence at the seal interface. Reduced turbulence helps minimize noise and vibrations during operation, for smoother, quieter running across the full range of media the union handles.
The 105 Series pairs a rugged cast housing with a maintenance-friendly internal layout, so the union stays in service without a full replacement when a seal eventually wears.
Housing and rotor are made from casted stainless steel material for strength and durability, keeping the union corrosion-resistant across water, gas, hot oil, and abrasive chemical service.
A robust self-supported construction gives reliable operation without depending on an external support arm or bracket to carry the union's own weight.
Both rotary and stationary seals are replaceable for easy maintenance and longer service life, with various seal combinations available to suit different operating conditions.

The 105 Series' seal combinations and cast stainless steel construction are matched to the pressure and temperature limits of each media group it handles.
Rated to 10 bar and 90°C — the standard duty condition for general industrial water and gas transfer circuits.
Rated to 20 bar at up to 70°C, with seal combinations selected to suit hot oil circuits specifically.
Various seal combinations are available to suit abrasive or aggressive chemical media, matched to the actual fluid condition in service.
Its combination of durable cast construction, low noise operation, and easy seal replacement makes the 105 Series a practical fit anywhere general-purpose rotary union performance is needed without the cost of a specialised, high-pressure design.
Standard-duty circuits running up to 10 bar and 90°C, where reliable sealing and low maintenance overhead matter more than a specialised pressure rating.
Hot oil applications running up to 20 bar and 70°C, where cast stainless steel construction holds up to sustained thermal cycling.
Applications carrying high abrasive chemicals, where the appropriate seal combination is selected at the time of order to match the actual fluid condition.
Any general-purpose fluid transfer application looking for durable construction, low noise, and straightforward seal maintenance over the union's working life.
