How to Install a Custom Tap Handle on a Hopsy SUB System

So you purchased a Hopsy Beer Club kit and are anxious to receive it. You went as far as to order a customized tap handle from Etsy with your name on it. Alas, the Hopsy kit arrives but to your dismay, your custom tap handle does not screw onto the Hopsy SUB counter top kegerator! What to do?!

Unlike a traditional standard tap and faucet system, the SUB system tap handle has an integrated screw that then screws INTO the faucet assembly instead of the reverse, where the screw is on the faucet and the tap handle is screwed ONTO it.

To solve this problem, you’ll need to find a bolt or a spring plunger with thread size that fits the handle screw socket on both the SUB system’s and a standard tap handle. Kinda like a double-ended dild… well you know what I mean.

The correct thread pitch is 1.5 mm and the correct thread length is 30 mm. So a metric M10 x 1.5 x 30 bolt, or an Imperial equivalent, would work just fine. You can find this bolt for super cheap in the hardware department at your local hardware store of choice.

I was able to find the perfect bolt by pure serendipity in my tool box at work that not only fits both the SUB system and my tap handle of choice, but the thread length is also a near match to for a near perfect installation! I had to use a washer so the tap handle is oriented correctly.

Because it is a bolt and I only needed the thread length, I had to saw off the head with a

I took the sawed off thread length, screwed it into the SUB system tap and then screwed on my cool Alaska Brewing, Co. Summer Ale orca tap handle onto the other end of the thread length sticking out of the SUB system’s tap.

Straight installation proved to be unsatisfactory as the orca handle was not centered properly.

To address this, I sandwiched an SAE 5/16″ washer between the handle and its removable handle collar. Some tap handles have the collar integrated into the base of the handle itself. If this is the case and you’ve come across an uncentered tap, you’ll need find a smaller width washer with 10 mm hole diameter to sandwich between the joint where the tap handle meets the SUB.

And there you have it, Hopsy SUB system with tap handle of your choice!

When installing a custom tap handle, take into consideration on the size of the base of the handle. If it is too big or bulky, it can interfere with the SUB’s faucet lid. The Alaskan Brewing, Co. Summer Ale handle is just the perfect size, although I still need to push the handle slightly to the right to be able to completely open the faucet lid. If you don’t mind maneuvering the TORP tube through the tap with a partially opened faucet lid, then you can use whatever tap handle you’d like.

    Thank you for this info by the way!

    I tried this method and it worked for the Hopsy end, but most US tap handles have standard 3/8 thread and don’t quite mate with metric thread well. My tap handle screwed on enough not too fall off, but would definitely not screw all the way on.

    I ordered an adaptor with a female metric end (to fit the bolt screwed into the Hopsy) and a male standard end to hopefully screw into the beer tap better. Found it online at a company called McMaster-Carr. They sell them on Amazon apparently as well made of aluminum.

    Thought I would post this to add some more insight
