Further, no special skill or tool is needed to assemble and install the fitting. If a fitting is needed in an area that may need to be disassembled for maintenance, the joints can be broken and reassembled without damage to the connection.
When assembling a pp compression fitting, avoid the temptation to over-tighten the nut. This could damage the ferrule inside or the tube itself. Once the nut stops turning with reasonable force, stop tightening. less
