United is not the first company to make a peg with a nylon sleeve, I doubt they will be the last, but they have looked at the standard alloy/nylon designs out there and made some improvements rather than following what everyone else has put out. Firstly they went for a heat treated cromoly inner peg over alloy, this was so that they could use a thinner material which saves weight, adds strength, and allows them to use a thicker, stronger and more durable nylon sleeve, without making a huge bean can peg. As for the nylon, not all nylon is the same, they went for a low friction and tough abrasion resistant material with anti fracture properties that will keep these pegs sliding longer than a lot of others. Tested by all of our team for over 10 months, and hit many times with a large hammer, they have not failed once.
