The 5/8 inch Compression Tube Sleeve and Insert Kit is designed to help create a secure, leak resistant connection in compression plumbing systems. This kit includes a hard plastic sleeve and a compression insert that reinforce flexible tubing before a compression nut is tightened. By supporting the tubing from the inside and outside, the components help maintain proper tube shape and allow the fitting to compress evenly for a dependable seal. It is commonly used with plastic or poly tubing in household plumbing and low to medium pressure water supply applications.
