Oyviny RV 7 Pin Trailer Plug with IP68 Waterproof Seal Detachable 7 Way Round RV-Style Trailer Side Connector

I recently installed this Oyviny RV 7 Pin Trailer Plug on my utility trailer, and I’m really impressed with the overall build quality. The IP68 waterproof seal is no joke — I’ve driven through some serious rain and muddy conditions, and this connector held up flawlessly without any sign of moisture getting inside. The detachable design makes it easy to install and remove, which is super convenient when you’re dealing with multiple trailers or replacing old connectors. What stood out to me is how secure the wire clamp and locking collar are. Once you tighten everything down, the cable is locked in place with zero movement. The internal terminals are solid brass, so you’re getting a good, corrosion-resistant connection every time. Plus, the plug fits snugly into my truck’s 7-way socket with no looseness or risk of losing connection while driving. Installation was straightforward thanks to the clear markings inside for each wire, saving me time and hassle compared to cheaper plugs. This is perfect for anyone hauling RVs, utility trailers, or boat trailers that need a reliable 7-point wiring solution. Overall, this is a professional-grade plug at a great price. Highly recommend!

I like it. Easy to install and came with really good instructions and a decoder for the different wiring patterns. It assembled solid and seems fairly weather resistant. Its a Good product for a fair price. Id buy one again. Read more

The 7-way plug is well made. The outer shell feels solid. The waterproof gland seals tightly around the 3/4" cable. The internal piece with the terminals with screw down posts works well. The instructions are okay with a minor exception. Some of the words for the terminations are shifted down about half a line. I marked up my instructions to make it easier to read as I assembled the plug. Before cutting off the old plug I used an ohmmeter to determine the color code and layout of the wires. I attached marine-grade, ring terminals to the wires which simplified screwing down the wires. When I tested the cable, a couple wires were swapped. The ring terminations may it easy to correct the swap. I then coated the terminations with dielectric grease to reduce corrosion. I liked the plug well enough that I ordered a second one. I'll keep it in the trailer so that if the current plug gets damaged while I'm on the road, I can easily swap out the damaged plug. Read more

Locks into vehicle plug securely. You would have to break the lid to pull it from the locking tab. The connection points also hold well. Water tight seal against the plug wiring works well, but I did have to use a section of heat shrink to get my trailer wire insulation to a large enough diameter to get a solid seal. -1* Read more

My old plug for my travel trailer gave out. It suddenly started losing connection and my truck stating that i lost lights, brakes, and the trailer was disconnected. This all happened somewhat close to my house on my way back from a trip. I tried unplugging and plugging in on my way back, but it would keep losing and gaining connection. It was causing an alert to go off on my truck every few seconds and that can make a person go crazy. I bought this and it was pretty easy to replace. The hardest part was keeping the swarm of gnats out of my face when putting the new one on. Had to cut the old plug off and match up the pattern in the instructions. Wasn’t hard as once you find the starting point, the wires were already in line with the pattern i needed to follow. There were a couple thicker wires that were a little harder to get into the clips, but it was a pretty easy swap. It is sturdy and fixed all my prior issues with my previous plug. If i ever needed another 7 prong plug, i would buy this again. Read more

This makes the fourth seven pin plug I've needed to replace on my camper trailer in ten years or so. I seem to have bad luck with these, mainly due to corrosion and not making flush contact with my Tacoma's power receptacle. It's made from (apparently) high-impact plastic and has a threaded compression fixture to relieve tension stress on the cable housing and provide some measure of waterproofing. Rewiring does nor differ from any of the previous plugs I have done. I did find it prudent to wrap the area with electric tape, however. The head of the plug fits flush to the truck outlet and also engages nicely with the outlet's door to keep it stable and plugged in. I noted some others reporting distortion of the plug body from tightening the hex set screw. To have that happen you are tightening it way beyond necessity, which will be evident to any casual observer. All in all a good value. Will have to see how well it stands the test of time and the elements. Read more

THIS IS NOT WEATHERPROOF. THE "PLUG IN" END HAS NO GASKET OR "O" RING TO SEAL OUT THE WATER WHEN ITS UNPLUGGED FROM THE TRUCK. THE OTHER END, WHERE THE CORD GOES INTO, DOES HAVE SEALS TO KEEP OUT THE WATER. Other than that its good. Read more
