The Parker CPI TZ-SS series compression tube fitting ferrule is made of type 316 stainless steel, and is for use with a nut to connect tubing to a fitting. This single ferrule, when used with a stainless steel compression nut (sold separately), helps provide a leak-resistant seal in high-pressure applications. It is made of chemically hardened type 316 stainless steel that provides higher strength and greater corrosion resistance than untreated stainless steel. It is for use with Parker CPI single ferrule compression fittings and pairs with the BZ series compression nut (sold separately).

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.
