Product Q & A's:



Q.) What material are your standard fittings and dampers made from?

Our standard fittings and dampers offered for sale on this site are made from PVC   and CPVC extruded duct and Type I PVC and CPVC sheets.  The sheeting is 1/4 inch in thickness and the duct wall thickness varies with the diameter, approximately 1/4 inch or less.


Q.) What Schedule are the fittings and dampers?
Schedule 40 and 80 are a standardization that applies to PVC pipe and does not apply to duct or sheeting.  Pipe is typically used in applications where there is high pressure.  Duct is for use in low pressure ventilation environments.  The fittings and dampers offered here are designed for low pressure ventilation (gas stream) applications.


Q.) Can these fittings and dampers be used with Schedule 40 and 80 pipe?
These fittings and dampers can be attached to Schedule 40 and 80 pipe and will exhibit similar corrosion resistant and fire retardant properties.  The fittings are not appropriate for use with Schedule 40 or 80 pipe in high pressure situations (see above).


Q.) How do you attach the fittings and dampers?
The fittings and dampers are best attached via plastic welding.  If this option is not available, the fittings can be glued to the existing system using PVC cement.
