Editors Note: This is an advanced project that requires additional tools, skill and materials. This post outlines the process that Kris took to modify his keg lid with a weldless tri-clamp bulkhead. Product specifications can change over time, double check to make sure that current specifications match your needs.
Adding a Tri-clamp Fitting to a Homebrew Keg Lid
Carboys, conicals, buckets, kegs, etc. There is an ever-growing number of options for fermentation vessels. I recently moved away from carboys to experiment with pressurized fermentation. I didn’t feel like buying anything new, so why not repurpose a corny keg for fermentation? This past year I “right-sized” my batches down to 2.5-3 gallons making a corny the perfect size for fermenting. With a couple modifications (shortened dip tube, hop screen, etc), I had an old 5 gallon corny now as a dedicated fermenter. An added bonus was that it fit perfectly in my temp-controlled chest freezer.

I started seeing some other homebrew fermenters with tri-clamp connections on top. Blogs all around showed them used with blowoff tubes, thermowells, carbonation stones, CIP spray balls, etc. It seemed like a great universal connection with a ton of uses. Most importantly to me, I wanted the tri-clamp connection to build an oxygen-free dry hop dropper (that build is an article for another day).

Read on to see my trials and tribulations while adding a TC bulkhead to my corny lid.
Build note: This is a weldless build. If you’ve got the ability/skill/tools to weld stainless, go for it!
Safety Note: Ensure that you are using all tools properly and wearing all the proper PPE. You will be drilling/cutting metal which is both sharp and hot.
PLEASE BE CAREFUL WHEN FOLLOWING THESE INSTRUCTIONS.
