This stainless bulkhead requires a 7/8" (22mm) hole in your pot, and features a silicone O ring with a containment nut on the inside, and a flat silicone washer for the ouside of your pot to prevent leaks. Adds a 1/2" male NPT outlet to a pot. The side facing the interior of the pot is smooth and not threaded.

This bulkhead will not leak, because it has both an interior silicone O ring (with grooved nut to hold it in place without distortion), and an exterior flat silicone washer to act as another guard against leaks.  For the ultimate in sealing, we also recommend you use teflon tap (not included) on both the interior threads and the exterior threads.

Cooler conversion

Review by Robert on 6/1/2020

The bulk head fitting is advertised as suitable for a cooler conversion. It is unacceptable for this purpose. The nipple is not long enough for a 10 gallon Igloo cooler. With the gaskets and washer in place, there is not enough room for the nut to catch the threads. This would work well for a kettle, not a cooler.

Q: Do you think this item would work on a 3/16" walled vessel? How long is the threaded section of the inside piece? Thanks.

A: The threads are 9/16" It would be a close fit, perhaps item B50, the variable length bulkhead would allow for more breathing room.
