Machined Screw Top (Matte SS)

AEROSPACE QUALITY

Precision-machined from solid matte stainless steel, this replacement screw top is produced to original Jacob Bromwell® specifications for exact fit and balanced weight.

Keep your Jacob Bromwell® matte stainless steel flask looking as sharp as possible, or keep a few on hand as spare parts—which is especially useful if you travel with your flask. Threaded for smooth engagement and engineered for a secure, leak-resistant seal, it restores the flask to its intended performance without altering silhouette or proportion. The diamond-pattern knurling provides confident grip, while the restrained matte finish preserves the disciplined character of the vessel. Built from 22-gauge solid stainless steel, this component ensures continuity of form and function — as originally designed.

Imperfectly Perfect: Minor imperfections lend charm, depth, and individuality to each piece and are a natural part of the 100% handmade process. Embrace the imperfect. This is the Jacob Bromwell® way.
