Brass Dome Pipe Cap for DIY Dimmer Switches

Solid Unfinished Brass Dome Cap – For Custom Dimmer Switch & Lamp Builds Crafted from solid, unfinished brass, this decorative domed pipe cap threads into a 1½ inch NPT fitting—perfect for creating custom dimmer switch enclosures or adding a distinctive finishing touch to your DIY lighting builds. Ideal for steampunk pipe lamps and other industrial-inspired designs, it’s a functional piece that also delivers visual impact. Get inspiration from my dimmer design here. Because it’s real unfinished brass, it will naturally tarnish and age into a warm antique patina over time, adding authentic character that can’t be faked. Leave it to weather for a rugged vintage look or polish it to maintain its shine—either way, it’s a small detail that makes a big difference in your custom lighting. Select an option: A. Flat Cap or B. Acorn-Style Cap   Black pipe fitting not included
