MiniBrew™ EZ Seal™ Stainless Steel Weldless Bulkhead Fitting

The leak-proof, OEM-ready way to add a threaded port to any tank — no welding required.
SS304 • Female NPT • Dual-rib gasket seal • Sizes: 1/2", 3/4", 1" (plus larger options)

If you’ve ever chased leaks, loosened fittings, or “almost-sealed” bulkheads… this is the fix.

The MiniBrew™ EZ Seal™ Weldless Bulkhead is a precision-machined, stainless steel bulkhead fitting designed to create a repeatable, high-integrity seal through the wall of a vessel. It’s used by homebrewers and fabricators — and it’s trusted by OEMs and engineers — because it installs cleanly, holds tight, and performs reliably in real-world fluid handling.

Why EZ Seal is the #1 seller ✅

True leak-resistant seal (dual-rib gasket design)

Each gasket is built with two raised sealing ribs that compress against the tank wall for a stronger seal and better resistance to small surface imperfections.

Left-hand thread lock (stays tight under pressure)

EZ Seal uses left-hand threading to help prevent loosening under internal pressure and vibration — a detail that matters when reliability is non-negotiable.

SS304 stainless steel (food-grade + corrosion resistant)

Precision-machined SS304 stainless stands up to repeated use, cleaning cycles, and demanding environments — from brewing and beverage to industrial fluid systems.

Weldless install = fast installs + easy service

No welding. No soldering. No special fabrication. Install, remove, clean, and reconfigure in minutes — ideal for prototyping, upgrades, and maintenance.

Built for real systems

Connect valves, pumps, sight glasses, hose barbs, instrumentation, and process lines using standard female NPT threads.

Choose your gasket option 🧼

  • Red (Food-Grade) — Buna-N / silicone blend option for food & beverage workflows

  • Brown (Industrial) — EPDM option for industrial/chemical-duty environments

(Choose the gasket that matches your application.)

Sizes & Hole Requirements (quick reference)

    Exactly what was needed.

    Exactly what I needed to fix my rig.

    No need to solder copper and stainless steel together with this bulkhead. I tried and failed! It makes a tight leak proof seal and the threaded inside take's copper fittings perfectly.

    Jeremy helped me through the process of finding the proper size bulkhead that I needed, which would have been difficult without his help. Can’t say enough about the quality and level of customer service I received.

    Great Customer Service

    The EZ Seal Weld-Less Bulkhead has been a great item for use in our manufacturing. But even better than this fitting is the customer service we have received from Minibrew. Every step of the ordering process has been simple, and even when we needed to make last minute changes to the shipping on one order it was taken care of very promptly and professionally.
