Plus and Minus Pinball Rubber Ring Kit

Replacement Rubber Set for Plus and Minus

The Plus and Minus is a 1935 electromechanical pinball machine from Gottlieb. Our complete rubber ring kit gives it the refresh it needs — every playfield rubber replaced with Eh⁺ silicone that won’t crack, fade, or lose bounce.

Accuracy matters. This Plus and Minus kit was built by cross-referencing Gottlieb’s official manual with multiple independent sources. We’ve corrected known manual errors and confirmed every rubber size, so what arrives matches what your machine actually needs.

What’s Included

A full set of playfield rubbers for Plus and Minus: rings in every required size, post parts, flipper rubbers, and shooter tip. No guesswork, no missing pieces.

Why Eh⁺ Silicone?

Eh⁺ is our custom-blended silicone formula designed specifically for pinball. It plays like quality rubber but lasts far longer — no cracking, no drying out, no sticky residue. Available in 16 colours so you can match your playfield or go bold.
