4L Double wall stainless steel keg

Cross-shaped spear built-in regulator with safety valve (without CO2 cartridge)

Highly polished faucet

Features

This 4L double wall keg can withstand pressures up to 120 PSI. A built-in safety valve releases pressure automatically when it reaches 30 PSI, well below the keg's maximum pressure tolerance, ensuring safe use without the risk of ruptures or leaks.
The double wall build provides a vacuum rate of 1*10^-4 Pa, greatly reducing thermal transfer and convection. This insulation capability maintains the temperature of a 4°C beverage to 8°C after 8 hours in a 24°C environment, keeping your drinks cold for extended periods.
The keg features CNC-machined threads at 31.5*1.5mm, paired with an integrated spear design, ensuring a perfect seal and stability even under high pressure. This precise construction prevents the keg from popping open due to internal over pressure.
The stainless-steel spear includes a relief valve capable of 15,000 cycles, providing reliable performance for up to 10 years or more. This feature ensures long-term usability and safety.
The faucet's interior and exterior surfaces are polished to a smoothness of 3.2μm and 1.6μm, respectively, that makes it easy to clean and prevents residue buildup.
The mini dispenser system maintains consistent pressure inside the keg, keeping homebrew, draft, and craft beer fresh for several weeks. The food-grade stainless steel material ensures that the beer retains its original flavor without contamination.
