The medium-pressure gaugeable tube fittings and adapter fittings provide a leak-tight gas seal and vibration resistance in applications up to 15,000 psig. Available in ¼-, 3/8- and ½-inch sizes, the all-316 stainless steel fittings come in a diverse range of fitting styles, including elbows, unions, bulkhead unions, reducing unions, tees, crosses, caps, and plugs. The fittings’ four precision components—a male nut, female body, front ferrule, and back ferrule—combine to apply a patented hinging-colleting action to grip and seal the tubing securely with no special tube preparation required. The fittings offer low weight and a compact profile to help save space in installations. According to the manufacturer, this level of performance meets the demand for higher pressure-rated components by the oil and gas industries.
