• No ugly terminations
• Gasketed connections have a precise, tight seal and does not require installation lubricant
• Terminations remain icicle free in freezing weather
• Tight seal at every joint..expands and contracts with weather and temperature changes, so there is no flexing or cracking in the venting
• Interior of 90° elbows are 88° to prevent standing condensation
• Higher sustained operating temperatures than PVC/CPVC
• Lightweight and easy to install
• Gasketed connections allow for removal and replacement of components
• Corrosion resistant
