What this bin holds

Our brass compression sleeves are small but mighty components for pipe connections. They help create a tight, leak-free seal in various systems.

These brass ferrule fittings have good corrosion resistance and are reusable. Each sleeve has a 4 mm (0.16 inch) inner diameter, suitable for connecting 4 mm (OD) copper pipes. They measure 5.5 x 4.2 mm (D*H) overall. You will receive 25 pieces in each pack.

Who takes it home

We see these sleeves used in hydraulic and pneumatic systems, HVAC, and humidifiers. They connect copper, brass, aluminum, or plastic tubing. To use, insert your pipe into the sleeve, then fix it with nuts to your pipe connectors. Always confirm your pipe's outer diameter before ordering.

  • Awesome! Fit machine "aluminum oiling line perfect!

  • Worked very well. Had to buy a special flare tool for the tubing, but, ultimately got a good seal for low pressure LP gas passing through a valve to an infrared burner I use for coffee roasting. Glad to get it back up and running. Cheers, --n.

  • These worked perfectly for my shimano mountain bike brakes to replace one I mangled installing the hydraulic line into the brake levers. Not sure what other uses there are for this size but was a lifesaver.
