Selecting the correct rotary joint is critical to ensuring leak-free operation, long service life, and optimal performance in your machinery. Carbon Rotofluid manufactures a comprehensive range of rotary joint & rotary union series, each engineered to handle specific media types and operating conditions. The guide below is designed to help engineers, procurement teams, and plant maintenance professionals identify the right CARBON series for their application at a glance.
CARBON brand rotary joints and rotary unions are designed to handle a wide variety of fluid media across industrial applications. The right series depends on which of the following the joint needs to handle, and under what pressure, temperature, and speed.
One of the most demanding media due to high temperature and pressure. Our steam-rated series are built with materials and seals that withstand continuous thermal stress without degradation.
Used extensively in textile, rubber, paper, and food processing industries. Our water-compatible series handle both low-pressure cooling circuits and high-temperature process water lines.
For pneumatic systems and gas transfer applications, our air and gas-rated joints provide reliable sealing under varying pressure conditions.
Thermic fluid systems operate at elevated temperatures and require joints with superior seal materials and body construction to prevent leakage and withstand thermal cycling.
High-pressure hydraulic circuits demand precise machining and robust sealing. Our hydraulic oil-rated series are built for durability in demanding fluid power applications.
Industrial coolant circuits in machining and metalworking applications require joints that resist the chemical composition of coolant fluids while maintaining consistent sealing performance.
Vacuum applications require a different approach to sealing. Our vacuum-rated series are designed to maintain integrity under negative pressure conditions without air ingress.
The table below outlines which CARBON series are suitable for each media type. For detailed technical specifications — including pressure ratings, temperature ranges, RPM limits, and available port sizes — refer to our product catalogue or contact our technical team directly.
