What is a Threaded Spear Keg?

G4 Kegs | August 1, 2023

What is a threaded spear keg?

Threaded kegs are built with the same integrity as our standard kegs, but come with threaded Sanke D System spears that offer additional functionality and benefits.

Unlike the common “drop-in” style spears on most kegs (which are not meant to be removed often or without special training and tools), threaded spears are designed to be removed easily, and can be manually screwed in and out of the keg’s neck with a threaded spear removal tool.

Why would I need them?

Threaded kegs are great for those who don't have professional, automatic filling or cleaning equipment needed to fill kegs or run them through a keg washer with the spear intact.

They are also convenient for those who may need access inside the keg frequently.

Threaded spear kegs are popular among taprooms dispensing cocktails on draft because of their ability to mix the recipe directly inside the keg. And, many kombucha producers prefer threaded-style kegs for easy access to visual inspection for sanitation purposes.

How do I use them?

The same as any other keg—with a few easy adjustments.

You'll need a threaded spear socket and ratchet or drive tool to remove and re-insert the spear. The threaded spear socket fits on any 1/2" drive tool. The socket locks into the top of the spear and you use the ratchet to loosen and unscrew it, counterclockwise.

Safety first!

Always use caution when removing the spear as the keg is pressurized. If the keg has a pressure release valve (our 2-gallon kegs do), always release the pressure before removing the valve. The pressure relief valve on our 2-gallon kegs will open automatically at 29–35 PSI to prevent over pressurization.

Threaded 1/6 barrels should be tightened to 55 pounds. Do not over tighten!

How should I clean them? 

All kegs from G4 come passivated, but should be sanitized before using.

Recommended cleaning method:

  1. Remove the threaded spear.
  2. Fill the keg with hot water (straight off a hot liquor tank works well).
  3. Screw the spear back in.
  4. Let the water sit inside the keg for five minutes, shaking the keg around frequently as needed to help the water loosen any debris.
  5. Hook up a coupler to the keg, and blow the water out with CO2, or air.
  6. Repeat these steps with a caustic solution (making sure to always blow out the keg with C02 after the caustic cycle), and then again with a sanitizer solution.

Note: Bleach should never be used on or in a keg. If you don't have caustic or sanitizer solution available, dish soap and hot water will suffice, but you should invest in the proper cleaning and sanitizer solutions for best results.
