Our take on the Stainless Tri-Clamp Weldless Bulkhead

A weldless panel-mount fitting that passes a tri-clamp connection through a tank or vacuum chamber wall without welding. A silicone or Buna-N gasket seats on the outside of the vessel, and the threaded body clamps the wall from both sides. It holds vacuum well and tolerates modest positive pressure, roughly 8-10 psi depending on the installation. It suits homebrewers, vacuum-chamber builders and fabricators who want a sanitary tri-clamp port without TIG welding.

Best forHomebrewers adding a tri-clamp port to a kettle or fermenterVacuum chamber and lid buildersFabricators who cannot or prefer not to weldSanitary plumbing retrofits on thin-wall vessels
Pros
  • No welding needed: mounts through a drilled hole
  • Tri-clamp face mates with standard sanitary fittings and gaskets
  • Holds vacuum reliably with grease on the sealing surface
  • Handles light positive pressure, around 8-10 psi
  • Fits walls up to 0.875 in thick
Cons
  • Not for high positive pressure
  • Vacuum performance depends on surface finish and grease
  • Requires an accurately sized hole: 1.3-1.4 in or 1.9-2.0 in
  • Threads are NPS, not tri-clamp, on the wall side

About the Stainless Tri-Clamp Weldless Bulkhead

This stainless steel tri-clamp bulkhead, also called a panel mount, mounts through a vessel wall without welding. It can be used on a vacuum chamber or a tank. A silicone or Buna-N tri-clamp gasket sits on the outside of the chamber or vessel.

It holds vacuum and can withstand positive pressure of about 8 to 10 psi. Depending on the installation geometry and materials, higher pressures may be possible, but it does not hold high positive pressure. For best vacuum results, apply vacuum grease to the sealing surface of the panel, lid or vessel wall.

Questions and answers

Will it hold a vacuum?
Yes. The gasket seals against the outside of the vessel wall and the fitting holds vacuum. Greasing the sealing surface gives the best results.
How much positive pressure can it take?
Around 8-10 psi is expected. Higher pressures are possible depending on wall geometry and material, but it is not built for high positive pressure.
What hole size do I need?
The 1.5 in model needs a 1.3-1.4 in hole. The 2 in model needs a 1.9-2.0 in hole.
What is the maximum wall thickness?
0.875 in. Thicker walls leave too little thread for the fitting to clamp.
What thread size does it use?
The 1.5 in model uses 1 in NPS threads. The 2 in model uses 1.5 in NPS threads.
Which gasket should I use?
Either silicone or Buna-N works. Silicone tolerates higher temperatures; Buna-N resists oils and is the usual choice for vacuum service.
Where is the Stainless Tri-Clamp Weldless Bulkhead cheapest?
At BVV, for $50.00, as of our latest check.
