It's the quality I would expect from Marinco, I.e. excellent. You would think someone would make a cheap knock off, but I couldn't find one anywhere.

Needed to replace a cracked ring on my RV's 30 amp cable. Worked beautifully no need for a heat gun to get it on.

YouTube has good videos on how to get the ring to go on. Easy once you know how

Links two 30 amp twist lock shore power lines end to end. What else is there to say. 5 stars for functionality, reduced to 4 because of cost.

Local shop wanted to sell us a whole new power cord when this was all we needed. Had to shave off a very little bit to make it fit. Works well.

Fit both my shore power cords to connect them to a 50 to dual 30 amp "Y" adapter. Easy to install. Keeps cord from getting accidently unplugged at the adapter. Be sure to confirm existing connector has at least one of the threaded rings, as this unit only comes with one. Extra rings are also available.

Fit perfectly on a 30A plug. Using a little dishwashing soap made installation quick and easy. Technique is similar to installing a tire on a rim. Amazon price was excellent and it was delivered quickly. Very happy with this purchase.

this ring should be included with the marinco 30 amp kit so you can connect the cord to the 90 degree cord to have a weather proof connection

I'm going to take care of this one. Installing it onto the plug was a pain... I was surprised I didn't break it trying. It fits snug and doesn't rotate that easily, making it difficult not to cross thread. I guess some light oil or something would help.

Amazon appears to mix reviews of different Marinco Sealing Rings together. This review is for the "30A Sealing Collar & Threaded Ring". It is intended to create a weather proof seal at the junction of two extension cords. It only works with Marinco cords. The two cords should already have sealing rings on the female ends (if not, you can get a new ring on this page). This Sealing Collar & Threaded Ring supplies another ring that you need to install on the male end of one of the cords (the end where the join will be made). You will have to slip the ring over the flange near the plug. Check the cord end that already has the ring installed as an example. This may seem impossible at first, but if you do it correctly, it's easy. As reviewer G. Or J. Horn suggested, start pushing the ring over the flange at a angle on one side. Work the ring over the flange at one of the leading edges, "similar to mounting a tire". After the half way point, it goes very quickly. I did not need to use any pry tools.Once you have the ring installed, attach the collar to one of the rings, connect the cords and attach the second ring to the other end of collar. Now you have a weather proof connection that will also secure the cords together.As some reviewers observed, these fine thread rings tend to stick, especially if dirt gets into the thread. Cleaning occupationally with a tooth brush, maybe using some window cleaner, helps. Applying a light coat of petroleum jelly doesn't hurt, but it also attracts dirt.

Difficult item to find at my local store. Ideal to seal up two cords when an extension is needed
