Why Ruitus
What Keeps Our Joints Running Year After Year
Six things customers keep coming back for.
ISO 9001:2015 Quality System
Documented procedures from incoming material to final inspection, audited and certified.
In-House Machining & Assembly
Critical sealing faces are machined in-house, so tolerance and surface finish stay under our control.
100% Pressure & Leakage Tested
Every unit is pressure and leakage tested before packing. Test records are traceable by serial number.
Custom Engineering from Drawing
Send the medium, temperature, pressure, speed and mounting space — we design the joint to fit.
Fast Quotation, Reliable Lead Time
Selection or custom proposal usually within one working day. Standard models ship from stock where available.
Spare Parts & After-Sales Support
Seal kits and wearing parts remain available for the full service life of every model we ship.
Applications
Where Our Rotary Joints Are Installed
From paper drying cylinders to steel rolling lines, our joints handle the media, temperature and speed of heavy industry.
