The Leak Defender® collar attaches to and replaces your old, worn fuel neck. It has an o-ring underneath, which seals to your existing fuel neck when tightened with a strap wrench and securely fastened with set screws. It is sealed along the outer perimeter, away from the inner perimeter, which is prone to wear and tear from everyday fueling. Get your fuel cap replacement today!

Learn MoreAbout Us
At Heavy Truck Solutions, we strive to provide the best truck accessories and products for medium and heavy-duty trucks. Our family-owned business has operated its own fleet of Kenworth, Peterbilt, and International trucks for more than 20 years, but we were tired of struggling to find the parts we often needed. So, we decided to set up shop and engineer our own truck parts! Our fleet demands quality craftsmanship, which is exactly what we seek to provide to fellow fleet owners and truck drivers.
Our goal to meet a wide range of needs, so we supply medium and heavy-duty truck parts and products for several big names, as well as replacement parts for when specific repairs are necessary. Browse our products by the brand they fit below, and contact us if you have any questions or concerns. We also offer our products wholesale to retailers and truck shops within the U.S., Canada, and Australia.
