8 mm (5/16") push‑in fitting, female FFL thread, high‑seal

This 8 mm push‑in female x FFL thread fitting is designed to provide superior sealing thanks to its double EPDM O‑ring system. This design increases the contact surface, greatly reduces the risk of leaks, and allows the tube to bend with a tighter radius without compromising the connection.

The female FFL thread (7/16" – 20 UNF / 1/4 SAE) is compatible with MFL Disconnects (ball lock and pin lock), as well as many brewing devices using this standard. The push‑in connection accepts 5/16" (8 mm) tubing.

This fitting is suitable for both gas and liquid applications and can be used up to 100 psi. No clamp is required: simply insert the tube with a clean, straight cut, then press the collar to remove it.

Why choose this product?

• Double EPDM O‑ring providing enhanced sealing.
• Compatible with MFL Disconnects and many FFL‑threaded devices.
• Quick, clamp‑free installation, suitable for gas and liquid.
