Understanding media compatibility

What each medium demands from the joint

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.

Steam

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.

Hot Water & Cooling Water

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.

Air & Gas

For pneumatic systems and gas transfer applications, our air and gas-rated joints provide reliable sealing under varying pressure conditions.

Thermic Fluid (Hot Oil)

Thermic fluid systems operate at elevated temperatures and require joints with superior seal materials and body construction to prevent leakage and withstand thermal cycling.

Hydraulic Oil

High-pressure hydraulic circuits demand precise machining and robust sealing. Our hydraulic oil-rated series are built for durability in demanding fluid power applications.

Coolant

Industrial coolant circuits in machining and metalworking applications require joints that resist the chemical composition of coolant fluids while maintaining consistent sealing performance.

Vacuum

Vacuum applications require a different approach to sealing. Our vacuum-rated series are designed to maintain integrity under negative pressure conditions without air ingress.
