Carlon E945N – Frequently Asked Questions

1) What trade sizes does the Carlon E945 PVC expansion coupling come in?
The Carlon E945 gray PVC expansion coupling runs from 1/2 inch through 6 inch trade size: 1/2 (E945D), 3/4 (E945E), 1 (E945F), 1-1/4 (E945G), 1-1/2 (E945H), 2 (E945J), 2-1/2 (E945K), 3 (E945L), 3-1/2 (E945M), 4 (E945N), 5 (E945P) and 6 inch (E945R). Order by the trade size of the conduit run it sits in, not by the coupling body size.
2) Do I need an expansion fitting on an outdoor PVC conduit run, or can I just glue it straight through?
PVC moves a lot with temperature, and on an exposed run that movement has to go somewhere. The Carlon E945 coupling exists exactly to absorb length change from temperature swings in exposed conduit, so the run does not bow, pull a box loose, or crack a joint. Runs buried in concrete or below grade are held in place and generally do not see the same free movement; the fitting earns its place on rooftop, exterior wall, and long exposed indoor runs in unconditioned space.
3) How do I know where to set the piston on a PVC expansion coupling when I install it?
The E945 has a molded-in mid-point indicator on the piston. You set the piston so the indicator is showing at installation when the conduit is at a mid-range temperature, which leaves travel in both directions so the run can grow in summer heat and pull back in the cold. Setting it flush at either extreme is the classic mistake, and it means one direction of movement has nowhere to go.
4) How much room do I need to leave in the run for a Carlon expansion coupling?
Plan for a fitting body about 9.71 inches long in the run. On a retrofit that matters: you are cutting that much conduit out and the coupling has to sit where its piston can travel freely, not tight against a strap or a box. Leave the section unstrapped either side of the fitting so the conduit can actually move.
5) Will a gray PVC expansion coupling match my existing gray conduit run?
It will. The E945 is molded in gray PVC, the standard color for rigid nonmetallic electrical conduit, with an unpolished, unbrushed molded finish, so it reads the same as the Schedule 40 and 80 conduit around it on an exposed wall or rooftop.
6) Does the Carlon expansion coupling have an inspection cover or access opening?
No. The E945 is a sealed expansion fitting with no inspection opening or cover, so there is no access point to open once it is installed. If a job spec calls for a fitting with a removable cover for pulling or inspection, this is not that fitting, and you would be looking at a conduit body instead.
7) How are Carlon E945 expansion couplings packed for a large conduit job?
Standard outer pack is 20 pieces in a carton measuring 8.625 x 5.875 x 6.5 inches, with a shipping weight of about 21 pounds per 100 pieces. On a job where you are dropping an expansion fitting into every long exposed run, that carton quantity is what to count against your takeoff.
