APPLICATION
TECHNICAL
When bonding with HVAC SUPER PRO, the pipe is not damaged. Our lab’s equipment goes to 2,500 psi. Every batch is tested to 2,500 psi, and a failure of the bond or the pipe has never occurred. Therefore, the minimum burst strength has been established at 2,500 psi, although it is actually much higher.
COMMON APPLICATION ERRORS
1) The clearance between the connector and tubing was less than 5 thousandths of an inch or greater than 20 thousandths of an inch.
2) The bonded connection was disturbed during the mandatory 3 or 5 minute bonding period. This is the period when the bond is changing from a liquid to a solid state.
3) The bonding areas were not sanded with 60-grit emery cloth.
4) While making the last connection, pressure was created inside the tubing causing the connection to move during the bonding period.
5) A brazed connection was made in close proximity to an HVAC SUPER PRO bond, creating transferred heat of 450 Degrees F or greater.
6) Connections to long pieces of tubing were not supported – creating stress on bonding area during the 3 or 5 minute bonding period.
7) When replacing a unit, stretching the current tubing to make it fit. The stress on the tubing will stress the bond and cause it not to bond correctly. An additional piece of tubing should be added to make the tubing the correct length.
8) There was refrigerant and/or oil present in the bonding area.
9) HVAC SUPER PRO was not applied completely around the outside of the tubing and/or the inside of the connector.
10) The tubing and/or connector were wiped after sanding.
11) The bottle was not shaken before application.
