Base Recirculation Options:
- Plastic Only - You can buy just the loc-line assembly including the 1/2" male connector, 90 degree elbow, and 14 flexible segments and thread it into your own bulkhead and provide a maximum vertical drop of about 12" with the last two links bent to horizontal. (shown on the left of the picture).
- Weldless Kit - with all piece shown to the right. After drilling a 7/8" hole in the top sidewall of your metal mashtun, use the SS washer on the inside and silicone flat gasket on the outside just behind the Camlock Type A Fitting. Of course this only works if you're subscribed to the use of Cam Locks for your disconnect system.(shown in the middle of the picture). It provides a maximum vertical drop of about 12" with the last two links bent to horizontal.
- Kit for Thick Cooler Lids - This kit deletes the lockline elbow so that the straight connector is inline with the tube. It comes with a metal washer, silicone gasket and 1/2" NPT coupling. Drill a 13/16" or 7/8" hole in the underside of the lid and a 1-1/8" hole in the topside of the lid for the coupling to fit into. You can then put either a hose barb or camlock type F into the top of the coupling (not include, buy elsewhere on this site). This kit will work with lids that are up up to about 1.5" thick, e.g. 10 gallon round Igloo. It will also work with Rubbermaid/Gott cooler lids, but you can acheive a lower profile with the regular weldless kit if you make the hole at a location where the top and bottom plastic gets close together. This kit is shown on the far right of the picture. This kit comes standard with 16 straight links for a height drop of about 13" when the bottom is curved to horizontal.
Note: After you select one of the first three options in the dropdown below (and click the Add to Cart button), you may aditionally select in the dropdown to add additional length to the kits. 3 more links will give you another 2.75" of drop and six links gives you another 5" of drop.
