About S+R Duct Couplers

DC-10 Duct Couplers are two-piece split design held together by 4 stainless steel bolts. The DC-10 connects two ends of inner duct while sealing the joint against air leakage during a cable-air installation. The coupler is reusable or can be installed as a permanent connection. The coupler can easily be installed by one person with the DH-10 Duct Holder Tool and available in a variety of sizes.

Size: 3 1/4″ x 4″ x 3 1/2″ installed

Material: Corrosion resistant aluminum

Weight: 1 1/2 lbs. +/- depending upon duct size

Bolts: 4 each stainless steel- 5/16-18NC x 1 1/4″ long

Tension Requirement: Annular pointed ridges on the inside of the coupler cause an interference fit with the outside of the duct creating a joing that takes a minimum of 4,000 lbs. to pull apart.

Air Sealing Requirement: 1/4″ thick x 3/4″ wide adhesive backed foam tape at the joint will exceed the requirement of a cable-air duct run: no more than a 20 psi drop in pressure in two minutes starting from a sealed pressure 100-130 psi.

Special Requirement: The coupler can be machined to connect two ducts of different outside diameters allowing for transition from one pipe size to another.
