Northern Brewer Bulkhead for Coolers

1. Remove the factory-installed spigot on the cooler. Remove the locknut, both silicone o-rings and both steel washers from the threaded nipple on the bulkhead.
2. If the wall of your cooler is less than 3/8” thick, put both steel washers on the threaded nipple; otherwise only put one washer on the threaded nipple.
   Northern Brewer coolers #7541 and 7542 require one washer.
3. Put the small silicone o-ring on the nipple and push the o-ring and the washer(s) all the way back.
4. Place the bulkhead assembly inside the cooler and push the threaded nipple through the spigot hole. The small o-ring should be resting against the inside wall of the cooler.
5. On the outside of the cooler, place the large o-ring on the nipple and push it against the outside wall of the cooler.
6. Thread the locknut onto the nipple and tighten it until it just touches the large o-ring.
7. Tighten from the inside only – hand-tighten, then use pliers. Initial tightening of the locknut from the outside can damage the o-ring.
8. Once snug, the locknut can be tightened the rest of the way from the outside.
