8mm (5/16")Female - 5 way Multi-Tee

The Duotight 8 mm (5/16") Female – 5‑Way Multi‑Tee is a compact, space‑saving solution for splitting gas or liquid lines with confidence. Instead of chaining multiple tees together, this single fitting lets you run up to four lines from one source, making it ideal for 4‑tap kegerators, keezer builds or any setup where clean, reliable distribution matters.

Engineered with Duotight’s signature double EPDM o‑ring sealing system, this fitting delivers exceptional leak resistance and superior holding strength. The dual o‑rings provide twice the sealing surface of standard push‑in fittings, allowing tighter hose bends without compromising the seal — a major advantage over generic alternatives.

Flush‑mountable, easy to install and designed for both gas and liquid applications, this Multi‑Tee works perfectly with EVABarrier 8 mm OD tubing and other compatible lines.

Built for reliability. Designed for tight spaces. Trusted for clean, leak‑free performance.

Why EPDM Matters

EPDM (Ethylene Propylene Rubber) offers outstanding chemical resistance and long‑term durability. It stands up to:

• Ozone
• Oils
• Acids and alkaline compounds
• Water, alcohol and beverages

It also resists aging and weathering far better than silicone or vinyl, with improved gas transmission rates and wear resistance — making it the top choice for food‑grade brewing applications.
