Knock Out Rubber Ring Kit
The Knock Out is a 1950 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.
Our process starts with the Gottlieb factory service manual for Knock Out, then layers in data from community-verified part lists and other trusted kit references. If the manual is wrong — and some are — we fix it.
Complete Playfield Coverage
Includes every rubber the Knock Out needs: silicone rings, post rubbers, post sleeves, flipper rubbers, and shooter tip.
The Eh⁺ Difference
Pinball rubbers take a beating. Eh⁺ silicone is formulated to handle it — thousands of ball hits without losing shape or bounce. Pick from 16 colours to customize your Knock Out, and enjoy fast shipping from Canada.
