The duotight 8mm (5/16") equal tee splitter is a versatile high-performance fitting designed to seamlessly split liquid or gas lines into two. This component is a staple in Kegerator Font kits, where it is frequently utilized to split a single gas line to multiple kegs.

Applications & Compatibility

  • EVABarrier Dual Barrier Line: These fittings can be pushed directly onto our 8mm OD EVABarrier Line
  • Split your line: Split your 8mm EVABarrier line to deliver gas to two different kegs; the more tee pieces you use the more kegs you can split it between.

8mm Tubing Compatibility

This 8mm duotight fitting is optimized for use with EVABarrier Dual Barrier Line, ensuring a reliable, leak-free seal. It is compatible with several hosing options, including:

The duotight Generation 2 Difference

Why settle for standard push-in fittings? duotight Generation 2 represents a massive leap in engineering over traditional acetal fittings.

Dual-Material Double O-Ring Design

The secret to our superior seal is a two-stage system using two different high-quality materials:

  1. EPDM O-Ring: Provides exceptional chemical and gas resistance.
  2. Silicone O-Ring: Maintains its shape and elasticity in sub-zero temperatures.

High-Performance Materials (POK)

Instead of standard Acetal, Generation 2 fittings are made from Polyketone (POK).

  • Higher Chemical Resistance: Withstands harsh brewery cleaners.
  • UV Protection: Won't become brittle over time.
  • Extreme Durability: Rated for over 300psi @ 25°C.

User-Friendly Features

  • Color-Coded Collets: Black denotes 8mm (5/16").
  • Depth Indicators: Includes >| |< indicators so you know the hose is fully seated.
  • No Clamps Necessary: Simply push to seal; push the collet to release.

We recommend using a Tube Cutter to ensure a perfectly straight, burr-free cut. An angled cut is the #1 cause of leaks in push-fit systems.
