Racingline Washer Bottle Cap

Racingline Washer Bottle Cap – VWR19G704

Give your engine bay a smarter, more finished look with the Racingline Billet Washer Bottle Cap. It’s a straight swap for the factory plastic cap, turning a bland, overlooked detail into a quality piece of engineering that complements any tidy bay build. Simple, affordable and effective.

Built from solid billet aluminium

Each cap is CNC-machined from a single block of aerospace-grade 6061 aluminium using 5-axis machinery, then hand-polished and finished in a gloss-anodised Midnight Black with laser-etched Racingline logos. The result is a hard-wearing, premium feel that won’t fade or scuff like the original plastic part.

Designed to fit properly

A nylon retaining ring replicates the factory indexing tabs, so the cap sits straight every time you close it – no crooked logos or misaligned text. A neat snap feature on the underside locks it securely in place, mirroring the action of the OEM cap.

Fitment
