Long Service Life – High quality elastomer compounds provide excellent resistance to hydraulic oils, steam, acids, and weathering
The RJT O-Ring Seal functions as the critical sealing component within an RJT sanitary union assembly:
Union Assembly – An RJT union consists of four components: a round slotted nut, a male part, a liner, and the O-ring gasket-
Positioning – The O-ring is placed between the male part and the liner within the union assembly, creating the sealing interface
Compression – When the RJT nut is tightened, the O-ring is compressed between the sealing faces of the male and liner components
Seal Formation – The compressed O-ring forms a hygienic, leak-proof seal that prevents product leakage and contamination
CIP Compatibility – The O-ring design allows for effective cleaning-in-place, as cleaning fluids can flow through the union without disassembly
