S-joint brass product "Ring Sleeve Joint"

The outer diameter dimensions are small! The lightweight design allows for minimal space usage in fittings.

Brass products "Ring Sleeve Fittings" do not require any processing on the pipe section due to the connection relying on rings (beads). Tightening is achieved through a connection with a bag nut, eliminating the need for special tools, flames, or adhesives. After use, inspection, removal for redecoration, and reinstallation can be done easily. The fittings are nickel-plated, providing sufficient corrosion resistance and an aesthetically pleasing appearance. 【Features】 ○ Usable with oil, water, air, etc. ○ Can be used with any fluid that does not corrode copper and brass. ○ The pressure can withstand considerable pressure (2.94 MPa) due to the ring completely adhering to the pipe under internal pressure (for resin pipes, up to 0.97 MPa). ○ The temperature range for use is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes. For more details, please contact us or download the catalog.
