Neon electrode brass caps and brass buttons and Bellows Air Gap brass ribbed caps.

"Must-Use"  Brass Caps and Brass Buttons

Neon brass caps, neon buttons (also known as penny caps), and the older ribbed electrode-to-housing brass caps are critical safety and performance components required for every glass or porcelain neon housing installation. These parts create a secure, arc-free connection between the neon tube electrode and the energized high-voltage housing spring assembly, helping ensure reliable operation and long service life.

​

Failing to use proper brass caps or buttons can result in electrical arcing, which may lead to premature component failure, damaged housings, or even fire hazards. In many modern neon transformer systems, arcing can also cause nuisance tripping, where the transformer detects an electrical fault and automatically shuts down the system. Simply relying on the neon tube electrode wires to make contact is unsafe and is never considered an acceptable installation practice. Proper brass connection components are essential for safe, dependable, and code-conscious neon sign operation.
