Dublin 1102 Series Replacement Rotary Union-Factory Price & Fast Delivery

Description

Product Overview of Dublin 1102 Series Rotary Union

Our Dublin 1102 Series Rotary Union replacement is a high-performance, shaft-mounted rotating seal designed to transfer steam, water, air, or other low-viscosity fluids from stationary piping to rotating equipment. Manufactured with precision and durability in mind, it offers a reliable and affordable alternative to the original Deublin models.

Our replacement for the Dublin 1102 Series Rotary Union offers industrial customers a cost-effective, durable, and reliable solution without compromising performance. Designed for slow rotation and swivel applications, this rotary union efficiently transfers hydraulic oil, air, and vacuum fluids between stationary and rotating parts in manufacturing and automation equipment.

Built with the same core principles as the original Dublin 1102, our version maintains essential features such as high-pressure capacity, superior seals, and corrosion resistance but delivers these at a significantly more competitive price, making it ideal for factories and production lines seeking value without sacrificing quality.

Key Features of Dublin 1102 Series Rotary Union

High Pressure & Temperature Ratings

Operates safely at pressures up to 1,160 psi (80 bar) and temperatures up to 392°F (200°C), suitable for demanding hydraulic and pneumatic systems.

Superior Sealing Performance

Incorporates advanced balanced mechanical seals—carbon graphite paired with hardened steel or silicon carbide—to ensure leak-free, long-lasting service and minimal internal friction.

Full Compatibility with Deublin 1102 Series

Our replacement rotary union is dimensionally interchangeable with Deublin 1102 Series, making installation simple and hassle-free. No modification needed.
