How To Bond

HVAC SUPER PRO SOLDERLESS COPPER BONDING is simple to use. Please view the online instructional video prior to use. 

Sand the outside of the tubing and inside the connector using 60-grit sanding cloth until it is shiny and free of all contaminants. Do not use a wire brush. Do not wipe the sanded area or clean it with a cloth or solvent. Leave the sanding dust on the tubing and connector. The use of 60-grit emery cloth increases the bonding area by cutting deep into the copper. Jackson Industries sell 60-grit emery cloth – item number JFC 089.

Cut the tip from the HVAC Super Pro bottle - the orifice should be small. Shake the bottle and squeeze a small amount out (one or two drops) and discard (this is the product that is in the tip of the tube and does not get mixed when you shake the bottle.)

Squeeze a bead of HVAC SUPER PRO completely around the circumference of the leading edge of the tubing (about ¼-inch from the end); and squeeze a small bead completely around the leading inner edge of the connector (as close as possible to the edge.) See detailed notes below.

Insert the tubing into the connector, bringing the tubing and connector into proper alignment within 10 seconds - beginning when the tubing is inserted. You must leave the bond undisturbed for 3 minutes. An aluminum connection must be left undisturbed for 5 minutes. In 12 minutes, the bond will withstand 850psi of refrigerant pressure. Aluminum requires 20 minutes to reach 850psi. When fully cured (approximately 2 hours) the bond will withstand 1200psi of refrigerant pressure.

Detailed Notes:   Appling HVAC Super Pro:

3/8-inch tubing and smaller - Place a thinner bead on the inside of the connector and the outside of the tubing than is placed on 1/2-inch and larger tubing.

3/4-inch tubing: Apply two beads on the inside of the connector and the outside of the tubing. One bead should be on the leading edge, and the second bead should be approximately 50% of the way down the bonding area.

1-inch and larger tubing: Spread HVAC Super Pro over the entire bonding area - inside the connector and the outside of the tubing. Recommended methods for spreading HVAC Super Pro include the use of the bottle nozzle, a toothpick, or other non-absorbent applicator. It is important not to wipe any area of the tubing or connector dry when spreading the bonding agent.

HVAC SUPER PRO will bond gaps up to 20 thousandths of an inch. It is equally important that the fit not be too tight as the connector will wipe off the HVAC SUPER PRO from the tubing when inserted into the connector; and, this will result in a poor bond. You should have 5 to 10 thousandths of an inch clearance for an ideal bond.

When bonding tubing to a threaded connector, it is best to tighten the connector and then bond the tubing to the connector. However, if the bond is made to the tubing first, do not tighten the connector by turning the tubing; instead, use two wrenches to tighten the threaded connector making sure the bond is not rotated.

If an error is made in a connection, heat the bond with a torch and pull the bond apart. Re-sand and re-apply HVAC SUPER PRO and re-connect the bond following the directions as stated above. If other bonds are close, protect them from the heat.
