TINWID1919 Fuel Cap for Kenworth Trucks - Non-Locking Non-Vented Replacement, OEM Fit

TINWID1919’s non-locking fuel cap is a direct-fit replacement designed for Kenworth trucks that require a non-vented cap on low-sulfur labeled tanks.

When you need a straightforward, specification-matching fuel cap for your Kenworth, this TINWID1919 cap delivers fit and function without a locking mechanism. It’s manufactured to match OEM dimensions so it installs easily, and it’s intended for fuel tanks that are already vented elsewhere. Before purchasing, confirm compatibility by measuring your current cap and checking any low-sulfur labeling on the tank.

Will this cap fit my Kenworth truck?

Most Kenworth applications that originally use a non-locking, non-vented cap for low-sulfur fuel tanks will accept this TINWID1919 replacement. Fit depends on matching the cap’s thread pattern and sealing face to the tank inlet.

• Measure your old cap’s diameter and thread type to verify match
• Check for "low sulfur" marking on the tank – this cap is specified for those tanks
• Designed to meet OEM fit, form, and function tolerances

How does a non-locking, non-vented cap affect fuel system performance?

A non-locking, non-vented cap simply provides a sealed closure without an integrated locking mechanism or vent path. Because it is non-vented, the tank must rely on a separate venting system to manage pressure equalization.

• Seals the fuel inlet to help prevent spills and contamination
• Requires a properly functioning tank vent or vented line
• Simple design reduces moving parts that can fail over time

What materials and quality standards should I expect?

TINWID1919 manufactures this cap to meet industry specifications for dimensions and sealing performance. The cap is built for durability in commercial truck environments where repeated removal and exposure to fuel and weather are routine.

• Constructed to maintain seal integrity under normal operating temperatures
• Meets fit and form criteria so replacement installs without modification
• Appropriate for standard diesel fuels labeled as low sulfur

How do I confirm this is the correct replacement before ordering?

Always compare your existing fuel cap to the replacement by visual inspection and measurement. Confirming thread size, sealing face, and whether your tank is labeled for low-sulfur fuel will prevent returns and downtime.

• Remove the current cap and measure outside diameter and thread pitch
• Inspect the tank label for low-sulfur or other fuel-type instructions
• Contact customer support with measurements if unsure about compatibility

Who is this for? This TINWID1919 fuel cap is ideal for fleet managers, owner-operators, and maintenance technicians who need a reliable, non-locking replacement for Kenworth trucks with low-sulfur labeled tanks. Choose this cap if your vehicle’s tank is already vented, you want an OEM-like fit without a locking feature, and you prefer a simple, serviceable closure that conforms to common replacement specifications.
