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: Green denotes 6.35mm (1/4"). Black denotes 8mm (5/8").
  • 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.
