The duotight 8mm (5/16") equal tee splitter is a highly versatile, high-performance push-in fitting engineered to seamlessly split a single liquid or gas line into two separate lines with minimal effort. This component serves as an essential staple in Kegerator Font kits and draft dispensing setups, where it is frequently utilised to divide a primary gas line to serve multiple kegs simultaneously or to split draft lines within compact setups. Designed for maximum reliability and ease of use, it features dual O-ring technology that ensures a robust, airtight, and leak-proof seal without requiring clamps or tools.

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 optimised 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.
