Stainless Steel Weldless Bulkhead 1/2'' NPT

The part works great once I figured out not to tighten to much. When installing this part DO NOT tighten with a lot of force. I tightened with my fingers and then gave a small turn with a wrench. Live and learn.

I purchased 2 of these for the top of my fermentor (where they wouldn't be in the wort). They work great and this is a great price.

As another reviewer stated, the nuts are narrow, making it a little difficult to keep a wrench on them; especially on the inside curvature of the kettle. Mine didn't leak from the get-go.

You can spend a lot more to get something like this. But why when this works very well! You need only to be aware that if these are over tightened they will surely leak. The trick to these, for a perfect seal, is to tighten them just until the o-ring slightly deforms. O-rings do not do well with being overly tight. My water proof camera case barely compresses its o-ring when you clamp the case shut but keeps water out from 1' to 100'.

This does not measure up to other bulkhead connectors available. The compression nuts on both sides of the vessel wall are way too narrow and there is no o-ring capture groove. The slightest pressure causes the o-rings to squeeze out and the connection to leak. Way too touchy! Many attempts were made and the connection always leaked.

Great product. Exactly what I needed to complete my economy Tun. Successfully brewed two batches with more to come. Fast shipping. Have ordered several products from AIH and have been very pleased with the products and services! I have recommended them highly to fellow Brewers.
