6.) How do I calculate the length of the QUIK-JOINT?

The user's pipe should engage 1 ¼" into each end of the QUIK-JOINT assembly. Whatever the distance is you need to span, add 2 ½". Refer to the table of dimensions for the minimum length per size, but we can manufacturer a QUIK-JOINT Coupling up to 20 ft in length.

7.) Does Guardian have a thru-wall coupling design?

YES - this is known as our Bulkhead coupling, furnished to any length required. Bulkhead design eliminates the need for welding while providing an air tight connection.
