Can the fit between the connector and the tubing be too tight for HVAC SUPER PRO to bond correctly?
• Yes! This is true for soldering, brazing, or the use of HVAC SUPER PRO. When the tubing fits snug against the connector, there is no space for the bonding material to bond between the tubing and the connector. An HVAC SUPER PRO bond requires a minimum clearance of 5 to 10 thousandths of an inch.
