duotight 6.35mm (1/4) Check Valve and Integrated Inline Regulator (to upgrade duotight manifold)

This is a 6.35mm (1/4") duotight inline regulator upgrade for the duotight manifold boards:
KL46244 - 8mm (5/16) duotight x 6 Way Manifold 
KL46237 - 8mm (5/16) duotight x 4 Way Manifold
KL46220 - 8mm (5/16) duotight x 2 Way Manifold

We also stock the 8mm version if you want to keep your line the same diameter, although we strongly recommend going to the smaller 3mm x 6.35mm gas line size for short draw systems. It allows you to get more lines within your Kegerator as well as a clear identifier which is gas.
Use this Red EVABarrier 3mm ID x 6.35mm OD x 12m Roll to show off your new gas line!

If you want to keep it all 8mm, we do have an 8mm version here.

Reminder: These upgrade inline regulators have a check valve in them. Each check can also be removed if you want gas or water to move freely in all directions. 

If you upgrade to the Digital Illuminated Gauge you cannot run liquid (water) through it. It will break it.

Assembly with Manifold

Using a thin flat headed screw driver, simply slide/pop the black retainer tabs and remove the ball valve
The duotight 8mm 6 way manifold is complete with mounting capabilities out of the box using button head screws. But if you're going to mount it on a kegerator, we would suggest using the duotight 8mm adhesive brackets (no drilling required)

(not suitable for liquids other than filtered water)

Applications & Compatibility

• 2-Way, 4-Way, and 6-Way Manifold: Upgrade your manifold to include this inline regulator without needing to stagger them as you would with the regular inline regulator.
  

6.35mm Tubing Compatibility

This 6.35mm duotight fitting is optimised for use with EVABarrier Dual Barrier Line. It is compatible with:

• KL25331 : 3mm ID x 6.35mm OD | 12m
• KL42758 : 3mm ID x 6.35mm OD | 12m (Red)
• KL42789: 3mm ID x 6.35mm OD | 12m (Black Lightshield)
• KL42758 : 3mm ID x 6.35mm OD | 12m (PE Water Line)

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.
