1.5" Tri-Clamp Pressure Reducing Valve/Vacuum Breaker 15PSI
15 PSI Vacuum Pressure Relief Valve – 1.5″ Tri-Clamp
Spring-Loaded Protection from Overpressure and Vacuum Collapse
This 15 PSI pressure and vacuum relief valve offers essential dual-direction protection for sealed brewing vessels. Spring-loaded for consistent and automatic operation, it prevents both dangerous overpressure and damaging vacuum conditions during fermentation, transfers, cold crashing, or CIP. Made from 304 stainless steel and designed to fit any standard 1.5″ tri-clamp port, it’s a compact, sanitary solution for fermenters, brite tanks, and Unitanks.Rated to relieve pressure at 15 PSI and break vacuum below atmospheric pressure.
Spring-loaded mechanism ensures reliable and repeatable function.
Protects tanks from pressure spikes and collapse due to cleaning, draining, or temperature swings.
Constructed from 304 stainless steel for sanitary, corrosion-resistant performance.
Compact tri-clamp design is easy to install and remove.
Ideal for use on fermenters, brite tanks, or any sealed pressure-capable brewing vessel.
How It Works
The internal stainless spring opens the valve to vent excess pressure above 15 PSI and allows air in when vacuum conditions occur. This prevents tank deformation and maintains safe operating conditions in closed systems.Applications

FOUNDER STORY
Hi, I’m Steven, founder and CEO of Bräu Supply.
Like many of you, I started brewing because I was obsessed with crafting beer that wasn’t just good—but exceptional. What I quickly realized was that most homebrewing systems were either too clunky, too limiting, or simply couldn’t deliver the kind of precision I was after. So, I set out to solve that.
My mission was simple - Build the most advanced, fully customizable brewing system for serious homebrewers.
Something reliable, compact, built to last for decades—and most importantly, capable of producing ridiculously delicious, consistent, high-quality beer every single time.
That mission led to years of prototyping, testing dozens of materials and configurations, and working with a growing community of brewers. The result? Unibräu—our flagship all-in-one brewing system.
Launched from our 2017 Kickstarter campaign, Unibräu became the world’s first countertop electric brewing system, designed for both beginners and seasoned brewers. Whether you're brewing from your kitchen, garage, basement, or backyard, it fits seamlessly into your life while delivering commercial-grade results.
With Unibräu, everything just clicks—from heating to chilling, every step is streamlined into an intuitive six-step process. You’re in full control, from grain to glass.
In 2023, The Spruce voted Unibräu the Best Electric Homebrewing System, and honestly, I couldn’t agree more.
Whether you're just getting started or you're already deep into your brewing journey, I promise you this:
Once you brew with Unibräu, there’s no going back.
It’s not just a brewing system. It’s the ultimate brewing experience—start to finish.
