duotight - 6.35mm (1/4'') Screwlock x 8mm (5/16'') - Reducer Elbow

This handy little push-in fitting makes setting up your line an absolute breeze—just shove the tubing in from both ends, and you're good to go! It's your go-to play whenever you need an extra-sturdy, leak-free connection on a rigid port that won't budge under pressure.

It offers dual functionality: one side rocks a standard 8mm (5/16) duotight push-in connection, while the other side features a heavy-duty compression-adapted Screw Lock tailored specifically for 1/4" (6.35mm) rigid fittings.

If you're looking to turn a tight corner, this fitting also comes in a handy duotight 8mm x 8mm Screwlock elbow version!

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.
