Maintain the integrity of your machinery with our High-Performance Copper Compression Sleeves. Essential for any centralized lubrication system or CNC machine center, these metal seal rings (also known as ferrules or olives) provide the critical seal between your tubing and compression fittings.
Unlike plastic alternatives, these copper rings offer superior resistance to oil, heat, and vibration.
Available diameters from 4mm to 16mm
OPTIMIZED FOR LUBRICATION SYSTEMS: Designed specifically as straight-through joints for sleeve-type fittings, these connectors ensure the smooth transmission of grease and lubricating oil, guaranteeing the stable and efficient operation of your equipment.
