Product identity

The Velvac 600186 is a silver aluminium fuel cap designed for diesel tanks with a 3 1/2 inch neck diameter and 3 3/8 inch neck length. It suits fleet operators and vehicle owners who need a vented, non-locking closure with a tethered chain and cross bar.

Fitment check

Verify that your tank neck matches the 3 1/2 inch diameter and 3 3/8 inch length before ordering. The cap uses a 5.5 threads per inch pattern, so confirm the thread pitch on the existing filler neck. This item is not for buyers who need a locking cap or a different venting specification.

Build and daily use

The aluminium body resists corrosion while the attached chain and cross bar keep the cap secured during refuelling. A vented design allows pressure equalisation in diesel systems, and the non-locking mechanism speeds up access for high-frequency stops.

Questions about this item

Does the Velvac 600186 fuel cap come with a chain and cross bar attached?

Yes, the cap is supplied with a threaded chain and cross bar already fitted, so no extra retaining hardware is needed.

How do I know if the 5.5 threads per inch specification matches my tank neck?

Measure the existing cap or neck threads; if they are 5.5 threads per inch the Velvac 600186 will screw on directly.

What does the vented design do when the cap is on a diesel tank?

The vent allows air to enter as fuel is drawn out, preventing vacuum build-up that can starve the engine.
