While my weldless kit is the easiest solution for a completely fresh vessel, many brewers have already outfitted their vessels with couplings that have been welded in. The simple solution is a basic street elbow as shown in the picture. This kit has several options depending on what you have on your kettle already.
- 19" Polycarbonate Tubing rated to 250F.
- Stainless Hardware
- Black Vinyl Numbers for each gallon mark from 2 to 15.(5-50 liter also available, contact me)
- 2.5" long eyebolt (may or may not be long enough depending on how you weld your coupling in).
- This kit requires that you already have a coupling installed in the lower sidewall of your vessel (or want to have one welded in).
- Put a few turns of teflon tape on the threads of the sightglass elbow and thread it in until the clear tubing is vertical and the fitting is snug and leak free.
Options (click on the picture for more detail)
- The basic kit presents 1/4" NPT male threads to your vessel (you have your own 1/4" NPT coupling welded in already).
- The next option adds a 1/4" NPT half coupling that you must weld into your vessel. The rest of the kit threads into that.
- The last option adapts the 1/4" NPT male threads to 1/2" NPT. (you have your own 1/2" NPT coupling welded in already)
The standard calibration numbers included with this kit is 2-15 gallons. If you have a slightly larger vessel than 15 gallons, you can also add an extension strip that will add numbers 16-25 as well as 24 smaller arrows for 1/2 gallon increments below. If you would like to substitute 5-60 numbers for Litres, you must select "substitute 5-60 litres" in the dropdown below and click the "add to cart" button separately.
PLEASE BE AWARE that polycarbonate tubing is sensitive to long exposure times some cleaning chemicals. Read more about it HERE prior to purchasing.
It is also highly recommended that you add at least one 20" long, 1/4" diameter nylon brush to your order for occassional cleaning of the interior of the entire sight tube (use with water or your favorite kettle cleaning detergent). $3.25
Please note that sight glass installs, into boil kettles especially, can benefit from use of a heat shield to keep the fittings and tubing from getting overheated. Overheating can lead to wort spurting out of the top of the tube or worse yet, and entire melt down. Some kettle and burner combinations can get by without a shield, but it is relatively inexpensive insurance to add one right from the start rather than incurring an additional shipping charge when you find out that you need one later. If you email us asking why your sight glass is bubbling or spitting, our recommendation will always be to make or buy a heatshield.Please click on the picture to get to the detailed page describing the optional sizes and add to cart button.
If you have a pot that is shorter than this sight tube, you may want to pick up this cheap tubing cutter ($4) if you don't already have one. It makes a nice straight cut that only requires a little sand paper cleanup. This small and affordable tubing cutter is perfect for trimming the top off any of our sight glass tubes that may extend over your pot/keg. Cutting your sight glass flush with the top of your vessel will protect it from getting snagged.
