Description

Nobody likes walking out to their tractor and finding someone helped themselves to your diesel overnight, or dealing with water in the fuel after a storm. A good fuel cap does more than keep the rain out – it prevents fuel theft, stops contamination, and maintains proper tank pressure. This locking cap with its precise 84mm threads keeps your fuel secure and your tank sealed up tight.

What You’re Getting

Secure lock mechanism that keeps thieves out of your fuel tank
Perfect 84mm inner diameter fit – no wobbling or loose connections
Easy-grip 89mm outer diameter that works even with thick work gloves
Proper venting system that prevents vacuum buildup while keeping contaminants out
Weather-resistant construction that won’t crack or fail after seasons in the sun

Built for Real Farm Work

Your Ford 35 Series, T4000 Series, TL, and TN tractors, along with Case JX models, are the dependable utility tractors that handle daily chores around the farm. Whether you’re feeding cattle with the loader, mowing pastures, or running the rotary cutter along waterways, these tractors often sit outside between jobs. That’s exactly when fuel theft becomes a problem, and why a locking cap makes sense for these workhorses that can’t always be parked in the barn.

Made to Last

This cap is built to handle everything farm life throws at it – temperature swings, UV exposure, vibration, and the occasional bump from equipment or tree branches. The seal maintains proper tank ventilation while keeping water, dirt, and debris out of your fuel system. The locking mechanism is simple and reliable, designed to work even when it gets dusty or dirty.

Good to Know

Installation is straightforward – just thread it on until the gasket seats firmly. Don’t overtighten, as this can damage the seal and make future removal difficult. If you’re switching from a non-locking cap, keep one key on your main ring and hide a spare somewhere on the tractor – nothing worse than locking yourself out of your own fuel tank. Check the tank opening for any old gasket material before installing the new cap.
