Duotight Push-In Fitting | 8 mm (5/16") x 1/2" BSP Female

Duotight 8 mm x 1/2" BSP Female Push-In Fitting

This Duotight fitting connects 4mm ID x 8mm OD EVABarrier tubing or 5mm ID x 8mm OD EVABarrier tubing to compatible 1/2" male BSP threaded hardware. It is a clean, clamp-free way to build compact draft gas and beverage line connections around regulators, manifolds, valves, and other threaded kegging parts.

The push-in side grips 8mm OD tubing, while the threaded side has a female 1/2" BSP connection. KegLand lists this as a Gen 2 Duotight fitting with a POK body, color-coded black collet for 8mm tubing, stainless locking teeth, and EPDM plus silicone seals for better cold-side sealing performance.

Best uses

• Connecting 8mm OD EVABarrier tubing to compatible 1/2" male threaded fittings.
• Draft beer and beverage line builds where a push-to-connect fitting is cleaner than a barbed fitting and clamp.
• Gas or liquid-side kegging setups using Duotight and EVABarrier components.

Compatibility note: This fitting is for 8mm OD tubing. It is not compatible with 6mm ID x 10mm OD line.

KegLand notes that this fitting includes a silicone washer on the threaded side, so thread tape is normally not needed. Do not use Duotight fittings with bleach or chlorinated cleaning chemicals, which can damage the fitting material and stainless components.
