Im glad i was able to get the o rings with out the plug it saved me money. They worked perfectly.
Those o-rings slipped right on and were a perfect fit.
I’m very happy with my purchase
Great product. Add a little oil to the seal and lock tight the threads and it will go right in and seal perfect.
I am in the process of rebuilding my 7.3 and i got to the rail plugs. Riff Raff was the easy first choice and i got them super speedy and great quality. Riff Raff also upped their sticker game with the new rubber emblems. Super impressed!
I was unhappy when these o-rings did not arrive a week after they were expected. The USPS claimed the package was delivered to my mailbox and was very unhelpful. I turned to Riffraff for guidance and was informed that the package was not insured, however they stepped up and sent me a replacement order at no charge. I'm not sure they would have done this on a larger order, but I'm very impressed nonetheless. Excellent affordable products and exceptional customer service.
Fixed my oil leaK!!!. Oil was running off the plug into my valley then down the back of the engine
I had a bad oil leak on the back of the head from the plug. Replaced it with this o-ring and it was gone. Fast shipping and a great price. Definitely buy more from here.
These seals were perfect replacement. I used them while I had my motor out of the truck. Was a convenient time to change them. Highly recommend.
Riffraff always has the good stuff.
