Video Transcript for Camco RV Sewer Hose Internal Coupler: The Breakdown
Today, we're going to be taking a look at the Camco RV sewer hose internal coupler. This coupler makes connecting two RV sewer hoses together quick and easy, without needing to worry about having the correct fittings. All you have to do is slide a hose over each end of the coupler and that's all there is to it. It's made from a durable black plastic construction. It's designed to fit all three-inch sewer hoses, and it's small enough so it can be stored inside of a four-inch RV bumper. Taking a look at the overall length, measuring from edge to edge, that's going to give us a measurement of about three and one-quarter of an inch.
Each slit end is going to measure about an inch and a half and then you're going to have that quarter inch gap in between them. That's going to do it for today's look at the Camco RV sewer hose internal coupler.

Not what I thought it was. Can't use them but probably not worth trying to return.

Very fast shipping, smooth transaction with Etrailer. Sewer coupling was good quality but this one is a little oversize.

The coupler's outside diameter is the same as the outside diameter of the sewer hose...It just doesn't fit!

they were well made but we could not get them to go inside the hose, no matter what we tried. we finaly cut them and forced the cuts together to make them work. i think all of them are that way, no matter where they are purchaced.

See what our Experts say about this Camco RV Sewer Hose Fittings
- How to Make a 40 foot Long RV Black Water Dump HoseTo give yourself 40 feet total of sewer hose you would need two of the # CAM39611 which are 20 feet long and then to connect them you would need the coupler part # CAM39203. For a 4 in 1 adapter to use on the hose you would need the part # CAM34971 as well.
view full answer... - Adapter to Join 2 RV Sewer Hoses TogetherWe do have some products that will work to join to sewer hoses together but not one that uses lugs on both sides. What we do have are the threaded adapter # F02-3102 and a non-threaded, similar version # CAM39203. I have linked videos on both parts for you. The parts from # F02-2029VP can't be separated out though.
view full answer... - Semi-Permanent RV Sewer Connections Made To Septic and Fresh Water Supply Needed - 75 FeetYour fresh water hose is an easy recommendation, I suggest the Camco RV drinking water hose, 5/8" diameter at 75' Long, # CAM22803. This is a reinforced PVC hose for drinking water made of FDA-approved materials and BPA-free. Because you state that you are new to RV living I will make the suggestion that you also use a water pressure regulator, I suggest the Camco RV Water Pressure Regulator, # CAM40055. Please see the attached video for a visual of product. Because inconsistent water...

view full answer... - How to Cover 75 Feet of Sewer Hose for RVThe longest hose we offer is 20 feet like with the part # CAM39611 so with four of those to equal a total of 80 feet and then three of the sewer hose couplers part # CAM39203 you'd have the 75 feet you mentioned covered.

- Fittings for HTS Super Heavy Duty RV Sewer HoseThe HTS Super Heavy Duty RV Sewer Hose w/ Built-In Clamps # CAM39901 can work with any standard sewer hose fittings with the exception of the red "E-Z Coupler" fittings. Camco specifically you could use adapters like Valterra Adapter # T1024VP, couplers like # CAM39203 as well as bayonet fittings and threaded fittings. I have added a link to our entire selection of hose fittings, so you can choose the ones you need, just make sure they aren't the E-Z Coupler type.
view full answer... - Recommended Extension Sewer Hose to Cover 80 Feet and Connect to a RhinoFlex Sewer HoseWe don't have just one 75' sewer hose, so the best we can do is recommend using 4 of the Camco HTS Standard RV Sewer Hose # CAM39611 and connect them using the Camco RV Sewer Hose Internal Coupler # CAM39203 which will give you 80' of hose. To connect this hose to your RhinoFlex hose, you'll just need to attach the Camco RV Sewer Hose Straight Adapter w/ Bayonets # CAM39413 using the Camco RV Sewer Hose Twist-It Clamps # CAM39553.
view full answer... - RV Sewer Hose Setup for Total Length of 35-FeetCamco hose # CAM39611 is a light-duty 20-foot hose without bayonet fittings on the ends so it can be used with the coupler # CAM39203 which installs inside the hoses to join two of them. If you prefer sewer hoses with bayonet fittings to make joining multiple hoses easier you might then prefer the heavy-duty Viper 10-foot hose # D04-0410. This has extra-thick 26-mil thermoplastic construction that will last a long time. For a total hose length of 35-feet you an use parts # D04-0275 (20-feet)...
view full answer... - Replacement Waste Plumbing Fittings For An RV Waste System If you have two connection points with a 3-1/2" inner diameter and just need something to slip into both of these connections then you would just need standard 3" ABS pipe, which we do not currently offer but you can get at a local hardware store. The outer diameter of the pipe would be 3-1/2" and you could slip it into the hub of the The Valterra RV Sewer Slip Hub with Flange - 3" # T1005. After slipping it over the pipe you can then attach a gate valve to the flange.
view full answer... - How To Use Internal Hose Coupler On RV Sewer Hoses As long as the RV sewer hoses are 3 inch in diameter without a bayonet fitting like Camco part # CAM39611 the hoses will slide over each end of the coupler part # CAM39203 to join them together. You do not need to heat the coupler up to seal the connection.
view full answer... - Need 20-foot RV Sewage Hose Extensions and ConnectorsWe do offer four RV sewage hose products in the 20-foot length you need. These include several heavy-duty and one standard-duty hose kit that can be seen on the included link. Some use camlock fittings and others use bayonet fittings. Since your existing hose has no fittings you could use Camco RV Sewer Hose Internal Coupler # CAM39203 to join the non-terminated ends of your multiple hoses together and then choose the additional hoses based on the type of connector you need. You can use...
