O-ring kit
The single most common cause of a leaky mini keg is a tired o-ring. This kit is the cheap, fast fix — a complete replacement set sized exactly for the Keg Smiths mini keg system, so you can rebuild every seal in one sitting and get back to a clean pour.
Why Keep a Kit on Hand
- Cheaper than guessing: Don't troubleshoot a slow leak for an hour — just reseat every ring and you're done.
- Exact-fit sizing: Cut to the dimensions used on the Keg Smiths cap, spear, and faucet — no scavenging the hardware-store o-ring drawer.
- Food-safe rubber: Same FDA-grade material as the originals; no funky aftertaste in your beer or cold brew.
What's in the Kit
- Cap o-ring (top of keg)
- Spear o-rings (multiple — for spear shaft and base)
- Faucet shank o-ring

How to Use
Disassemble the keg per the instruction sheet that came with your system. Pull the old o-rings (a fingernail or plastic pick works fine — don't use metal). Lubricate the new ones with a drop of food-grade keg lube or even a dab of olive oil, seat them in their grooves, and reassemble.
Frequently Asked Questions
How do I know which o-ring is leaking?
Reseat all of them. It takes a few minutes and is faster than chasing a single slow leak.
Do I need keg lube?
A drop of food-grade keg lube (or olive oil) helps the rings seat and seal, but it is not strictly required.
How often should I replace o-rings?
Once a year for regular use, or any time a ring looks flattened, cracked, or stiff.
