## Description

The Parker A-Lok RU-316 series compression tube fitting is made of type 316 stainless steel, and connects tubing of different diameters in a straight run. This inline union allows quick disconnection of tubing for maintenance or fixture replacement. Twin ferrule compression fittings connect to tubing on both ends for a leak-resistant seal in high-pressure, high-vacuum, and high-vibration applications. This fitting is made of chemically hardened type 316 stainless steel that provides higher strength and greater corrosion resistance than untreated stainless steel. It is commonly used in chemical, petroleum, power generation, laboratory, and medical device plants. Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).Parker Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems for fluid handling, filtration, sealing and shielding, climate control, process control, and aerospace applications. The company, founded in 1918, is headquartered in Cleveland, OH.
