Legris 0124 18 00 Brass Compression Tube Sleeve 18mm

Product Description

The LEGRIS 0124 18 00 is a brass compression tube sleeve designed for use in compression-style tube fittings. The sleeve seats between the fitting body and the compression nut, creating a leak-resistant mechanical seal on the tube OD when the nut is tightened. Machined from brass, this sleeve provides corrosion resistance and reliable performance across a wide service temperature range of -40 degrees F to 250 degrees F, with a maximum working pressure of 536 psi. It is a standard consumable component replaced during tube fitting service or new assembly work by plumbers, HVAC technicians, and industrial maintenance professionals.

This sleeve is sized for 18mm tube outside diameter connections and is suited for use in fluid and pneumatic systems that use compression-type tube fittings. Typical applications include hydraulic and pneumatic plumbing lines, refrigeration tubing assemblies, and general-purpose fluid conveyance systems where a reliable compression seal is required. It is commonly installed in both residential and light commercial mechanical systems during new construction or service work.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians as part of compression fitting assembly or repair. Always depressurize and drain the line before disassembling any compression fitting. Slide the sleeve onto the tube before threading the compression nut, and ensure the tube is cut square and free of burrs for a proper seal. Refer to applicable IPC or system manufacturer guidelines for torque and fitting assembly procedures.
