Duotight push‑in fitting 8 mm (5/16") female to 5/8" thread

This 8 mm (5/16") push‑in fitting x 5/8" female thread is designed for reinforced sealing thanks to its double EPDM O‑ring system. This design increases the contact surface and greatly reduces the risk of leaks, while allowing the tube to bend with a tighter radius without compromising the connection.

The fitting is compatible with EVABarrier 4 mm ID x 8 mm OD and 5 mm ID x 8 mm OD tubing. It is not compatible with EVABarrier 6 mm ID x 10 mm OD. No clamp is required: simply insert the tube with a clean straight cut, then press the collar to remove it.

The 5/8" female thread is suitable for standard keg couplers, 5/8" draft shanks, and many brewing fittings using 5/8" threading. This push‑in fitting is designed for gas and liquid applications and can be used up to 100 psi. EPDM seals offer excellent chemical resistance, high durability, and compatibility with ozone, oils, alkaline and acidic compounds, water, alcohol, ketones and beverages.
