This fitting is a push in fitting so you just push the line in. It is mainly used where a stronger compression connection is required on a rigid port so you can attach 8mm EvaBarrier tubing to an 8mm diameter rigid pipe.
One side is a standard 8mm (5/16) duotight push in fitting, where the other side is a compression adapted duotight (Screw Lock). The Screw Lock side can be used on any 8mm outer diameter rigid tubing.
Compatible with: - EVABarrier 4mm ID x 8mm OD line (item Z91), as well as 8mm diameter rigid tubing.
