duotight - 6.35mm (1/4'') Female x 6.35mm (1/4'') Female Push In Joiner

This straight joiner is designed to securely connect two 6.35mm (1/4") outer diameter (OD) hoses end-to-end, or to attach a 6.35mm OD hose to a rigid, 6.35mm duotight-compatible post. It provides a reliable, leak-free connection suitable for a variety of gas and liquid tubing setups, ensuring smooth, uninterrupted flow through your system.

Applications & Compatibility

• Hose to Hose: Join two 6.35mm OD hoses together.
  
• Hose to Barb: Join a 6.35mm barb to a 6.35mm OD hose - useful for carb caps or bronco taps and the like
• Barb to Barb: Why not join a bronco tap to a carb cap?

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").
• 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.
