EZ Seal Weld-Less Bulkhead

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
