John Guest straight union female fitting — 3/8 1/4
John Guest push-fit straight union female fitting with 'Grip & Seal' technology. The tube connects with a simple push, with no tools, soldering or gluing: the stainless grab ring locks the tube and the O-ring seals it. Ideal for drinking-water, water-treatment and compressed-air networks. Size: 3/8 1/4. Reference PP451222W.
Push-fit 'Grip & Seal' technology
The connection combines a stainless-steel grab ring, which holds the tube under pressure, with an O-ring that ensures the seal. The fitting is removable and reusable: push the release collet to free the tube. No heating, no flame, no chemicals — a considerable time saving and greater safety on site.
