duotight - 8mm (5/16”) Female x 9.5mm (3/8”) Female Reducer

This particular fitting is designed to reduce or drop down line size from a 9.5mm (3/8") outer diameter to an 8mm (1/4") outer diameter. It provides a reliable, seamless transition between different tubing sizes or rigid fittings without requiring complex adaptations or additional clamps.

It is highly useful across a variety of homebrewing and draft setup applications, including connecting to Carbonation caps, Short Shanks, and Bottling Guns.

Applications & Compatibility

• Line to line: Drop down line size from 9.5mm to 8mm, or increase it from 8mm to 9.5mm.
  
• Line to barb: Connect 9.5mm line to certain pressure gauges or Quick Swivel barbs

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.
