Tube Fittings Types
Rohrverschraubungen provide a reliable, necessary, and leak-free connection for the smooth flow of fluids and gas. They play an important role in various applications and industries.
There are different tube fittings types: Instrumentation compression tube fittings and Industrial tube fittings
Instrumentation Tube Fittings
Instrumentation tube fittings are popular and often used in instrumentation and analytical applications. They are operated by compressing single ferrule or double ferrules onto the tube. Instrumentation tube fittings do not require special tools to assemble, which makes them convenient for easy and quick installation. Instrumentation tube fittings comprise three parts: nut, ferrules (single or double), and body.
Instrumentation tube fittings are categorized as single ferrule tube fittings and Doppelklemmring-Rohrverschraubungen
Single ferrule tube fittings: One ferrule creates a leak-tight seal between the fitting body and the nut. They are suitable for low-pressure environments such as water treatments and plumbing and heating systems.
Double ferrule tube fittings: double ferrule (a front ferrule and a back ferrule). The front ferrule is for the sealing and the back ferrule provides the grip. They create a strong sealing. They are ideal for high-pressure applications such as the Oil & Gas industry and chemical industry.
Single ferrule tube fittings and double ferrule tube fittings have a variety of configurations to meet different requirements. Here are some common ones:
Straight Connectors (Union, Reduzierstück, Stecker, Female Connector )
Elbows (Union-Winkelstück, Männlicher Winkel, Female Elbow)
T-Stücke (Union Tee, Männliches Zweig-T-Shirt, Weibliches Zweig-T-Shirt, Herren Run Tee, Female Run Tee)
Bulkheads (Bulkhead Unions, Schottverbinder (Stecker), Schottverbinder (weiblich))
Union Crosses
Reducers

Industrial Tube fittings
Industrial tube fittings are mostly used in petrochemical, fluid power, and automotive industries. They are categorized as:
SAE flareless tube fittings
JIC and SAE 37° flared fittings
O-ring face seal fittings

Tube fittings types in different materials:
Stainless steel tube fittings: Stainless steel is ideal for high-pressure and corrosive environments. The temperature range is from -254℃ to 649℃. The pressure can reach 10,0000psi. The maximum allowable pressure can reach 20,000 psi.
Carbon steel tube fittings: The cost is more friendly. The temperature range is from -54℃-260℃. They are not suitable for low temperatures and high-corrosion environments. The maximum allowable pressure can reach 18,000 psi.
Brass/copper tube fittings: Brass has good corrosion resistance, and can endure low temperature. The temperature range is from -198℃-204℃. Brass material is suitable for low pressure at 3000 psi. So it is a kind of popular material.
