any difference between the orange and the grey glue?

Hi, Is there any difference between the orange and the grey glue when used for furnace exhaust vent? Thanks?

I think that orange label can is still the grey glue meant for PVC (65°C). We usually use this with furnace venting.

They may have changed their packaging although using an orange label is kind of confusing.

The orange glue is meant for CPVC (90°).  We usually use this with boiler venting.

I would just make sure the can says PVC or CPVC, depending on what you are installing.

Don't forget to use the clear or purple primer when working in 0°C weather.
