Video Transcript for Camco RV Replacement Plumbing Vent Cap Review

Today we're going to be looking at the Camco RV replacement plumbing vent cap and polar light part number CAM40034. This vent cap replaces a lost or damaged plumbing vent cap on your RV or camper. So now we're up here at the roof of our camper, this is kind of show you how this vent cap works. Now this vent cap is just the top portion of the vent, so you see here the whole entire vent itself is caulked down into the roof, the caulk is just going to help prevent any water from seeping in. You can see how this lifts up here which is how we will replace it, is there's these pins which would go into these holes. Now there's a screw hole here at the top of the vent cap which we're not actually going to take this off as there is a screw already on the cap and it is caulked over. So we don't want to break that seal.

Basically what you would do is you would just pinch in these two metal brackets here to go into the vent opening and then those pins would snap into here. Then what you would do is just take the existing screw from your old one if it by chance breaks off or just get a new one, it would just penetrate through the plastic here. That's just going to help really secure it, so if the pins break off or get weak, that screw is going to help secure it. Then what you would just do is just replace the caulk. Now this plumbing attic vent is for a one inch all the way up to two and three eights inch pipe. That'll complete today's review of the Camco RV replacement plumbing cap part number CAM40034.

Hello etrailer!

I dont always
write reviews as services can be variable and the reason i dont. That said, etrailer ...nailed it ....again. I built out a pull through snowmobile trailer with beds, heaters, etc into a very comfortable all weather rig. Etrailer supported me then and again for our little Nash. This order was supported first with email info from Meriah V and follow up from George after order placement, order shipment and receipt notice of arrival. Great products GREAT customer service. This is great customer service!

With this order, i purchased ventline replacement lids and fan-tastic vent-covers for our Nash. Easy install, great product. Allows us full open vent lids during weather or travel. Easy install too! Love em. Happy to know i have a go to company for the things i need for our RV. Will always stop in at etrailer first.

Thanks everyone.

Very good vent covers and easy to insta ll.


Product looks good and I think it will work fine on the open vent.


A little pricey but got here right on t ime


Great product, Great price, Great selection of products!


Worked great to replace the lost cap.


Great replacement for your OEM waste pipe through roof plumbing caps.


Purchased set of Dexter Nev-R-Adjust electric brake assemblies - completely assembled on a new backing plate - for 3500 lb Dexter axle on a Casita 17'. Since drums were off, included new bearings, races, seals, & caps along with partial drum grinding. As an old timer, I have rebuilt many brakes, bearings, etc. This job went as slick as any I have ever done. As soon as weather cooperated, done in 2 short sessions. etrailer was, as always, prompt on delivery with correct & complete parts. It doesn't hurt that they also provide extensive instructions for the first timer. Maybe not the cheapest but definitely the best parts & service.


Needed a replacement vent cap for one that had deteriorated. Original one had a base cemented to the roof. Installed easily in my 1 1/2" vent pipe and metal clips seem to hold it in place well.


Perfect replacement for my RV vent cap. Took minutes to install and looks great. Would purchase again and recommend product.


Very pleased with the product and how fast it shipped, fits very good will order again from you guys anytime, thanks for the product at a very good price, save me a lot of time running around trying to find the right cap at the local camper dealers.


The roof vent cap would have been great if it wasn't for the base plastic being old and dried out. I broke one trying to take apart and the other one trying to put together.


Fast shipping, correct parts, great price! Very easy to order from etrailer. Not the first time I've ordered from etrailer, will continue ordering from them.


Very good item and easy to install. The best part is they haven't come off of my motorhome after a year.


The vent cap installed just like described. It appears to be very secure. I’m happy with it.


The plumbing cap replacement is doing well and was very easy to replace.


used it as a temp fix for a broken vent till I had time to replace it correctly. Worked perfectly. It seemed a little too loose for me as a permanent fix by itself.


works better then having to replace complete assembly and reseal roof.


Great product!!! Fit perfectly, Excellent Shipper we have used this company numerous times and have never had a problem. Products exactly as described and fast shipping. Highly recommend!!!!


Fit like a glove. Even though not original equipment, still went on in less then 5 seconds. Very happy with purchase.


The cap was the right diameter for the base but in order to get it to sit down correctly I had to shorten the stem that recieves the securing screw.


Thanks to George and the folks at etrai ler


Products are as described, ordering was easy, same great service each time I place an order


Good enough. Hope they don't blow off while traveling.

Great deal
