(2 pack) Hilangsan 1.5" Tri Clamp Weldless Bulkhead Stainless Steel Compression Bulkhead Fittings Homebrew Kettle Bulkhead 1.5 inch TC Bulkhead for Brew Kettle

Worked awesome to add an electric element and a steam condenser to a 15G SSBrewtech kettle. 41mm hole saw worked perfectly for these fittings.

Good quality and works exactly as it should

Used on my craveller floating lid wine tanks to adapt the lid instead of the dry airlocks. Works great wish they made them with triclamp on both sides so I could use a cip ball for cleaning.

These weldless tri-clamp bulkhead fittings worked great. Easy to install. Wasn’t sure how well they’d work because they’re flat but the surface that I was attaching them to is curved. No leaks so far.

Good quality, as advertised, we'll fit. I would buy again.

These are nicely constructed with ground and polished surfaces on all the product contact points. The silicone washer is retained by a rabbet in the bulkhead which prevents it from just being squished out resulting in a better seal. The outside diameter is just under 40.75mm so a 41mm carbide hole saw should work just fine unlike the oversized 42mm saw you see with some more homebrew oriented kits. Most hole saws cut sloppy especially when using a hand drill so you will end up with a slightly over hole anyways.There is one minor detail that I won't deduct a star for but is a sign of potentially worn tooling or lack of a finishing step at the factory. Both pieces had a long and sharp burr on the inside of the bulkhead thread next to the seal. If you errantly run your finger across it, you can cut, slice, or stab yourself. The nuts also had some sharp edges near the end of the thread. These are easy enough to deburr but is not something most brewers will think about.That aside, these are an unbelievable value for what you get and I do strongly recommend them.

Well designed and well made. Surfaces are ground and polished, like expensive aerospace parts. The thick o-ring sits in a groove, and makes a tight seal. You would think that a flat fitting can’t make a good seal against a curved surface but it does, without leaks. Recommended.

Beefy piece of metal, happy they were, but with a thick screen gasket the flange was so thick my old school break over quick disconnect clamp was too narrow to snap shut, newer clamps were necessary.
