duotight – 8mm (5/16”) Female x 1/4 Inch BSP Male Thread (With Seated O-Ring)

This compact and practical duotight to 1/4 BSP threaded component is exceptionally useful, particularly across a wide variety of the gas fittings in our product range. Specifically, the 1/4 inch thread seamlessly integrates directly into the main regulator body, the various manifolds available in our lineup, and numerous other compatible hardware items that routinely utilise a standard 1/4 inch thread interface.

Applications & Compatibility

• Regulators: Can fit into the body of our MK4 and MK5 regulators.
  
• Manifolds: Can also replace the barbs on our gas line manifolds.
• Plumbing: Fits on any standard 1/4" BSP fitting.

8mm Tubing Compatibility

This 8mm duotight fitting is optimised for use with EVABarrier Dual Barrier Line. It is compatible with:

• KL06224: 4mm ID x 8mm OD | 12m
• KL06231: 5mm ID x 8mm OD | 12m
• KL42741: 5mm ID x 8mm OD | 12m (Red)
• KL42765: 4mm ID x 8mm OD | 12m (Black Lightshield)

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.
