NPT-UNF-ORFS Ellenbogen und T-Stücke

NPT, "National Pipe Tapered", is a commonly used pipe connection standard in the United States. NPT female has a tapered thread structure designed to provide a leak-proof connection for pipe fittings. The tapered thread structure allows the threads to seat against each other when tightened, providing a leak-proof seal.

NPT Elbows

• Function: NPT elbows are used to change the direction of pipe lines at angles such as 90° or 45° to alter the route of the pipeline. They provide secure and leak-proof connections due to the NPT threads.

• Material and Durability: NPT elbows are usually made of materials such as stainless steel, carbon steel, aluminum, and copper. These elbows must be resistant to high pressure while changing the direction of pipe lines.

• Areas of Use: NPT elbows are commonly used in plumbing, gas lines, industrial pipe systems, and liquid transport lines. They are preferred in systems requiring high pressure and leak-proof connections.

NPT T Connectors

• Function: NPT T connectors provide a three-way connection to the pipeline. By adding two side pipes to a main pipe, they create a 'T' shaped connection. These connections are leak-proof and secure due to the NPT threads.

• Material and Durability: NPT T connectors are generally made of the same materials and provide secure connections in high-pressure environments.

• Areas of Use: NPT T connectors are used in water, gas, oil, and chemical pipeline systems. They are also commonly used in plumbing installations.

2. UNF (Unified National Fine) Elbows and T Connectors

UNF, "Unified National Fine", is primarily known for its finer thread structures. UNF female threads are preferred in locations requiring precise connections and in systems using finer threads.

UNF Elbows

• Function: UNF elbows are used to change the direction of pipe lines at specific angles, usually 90° and 45°. They are used to create tight and smooth connections at the joints of UNF threaded pipes.

• Material and Durability: UNF elbows are generally made of aluminum, stainless steel, or steel. These connections are used in systems requiring precise and secure leak-proof seals.

• Areas of Use: UNF elbows are especially used in the automotive, aerospace, hydraulic systems, and other industrial systems requiring fine threads.

UNF T Connectors

• Function: UNF T connectors create 'T' shaped connections by combining three pipe lines. This connection is achieved by attaching both side pipes to the main pipe.

• Material and Durability: UNF T connectors are generally made of durable steel and stainless steel materials. The fine thread structure ensures precision and leak-proof seals at connection points.

• Areas of Use: UNF T connectors are used in the automotive industry, aerospace and space industries, and in industrial systems requiring high precision.

3. ORFS (O-Ring Face Seal) Elbows and T Connectors

ORFS, "O-Ring Face Seal" connection system is particularly used in hydraulic and pneumatic systems. ORFS connections provide leak-proof seals on the surfaces of connection elements using O-rings. This type of connection ensures safe and effective leak-proofing in high-pressure systems.

ORFS Elbows

• Function: ORFS elbows are used to change the direction of pipe lines. ORFS elbows typically change the pipe direction at 90° or 45° angles and are designed with O-ring sealing technology.

• Material and Durability: ORFS elbows are made of materials resistant to high pressure. These connections are used in environments requiring liquid leak-proofing in hydraulic systems.

• Areas of Use: ORFS elbows are widely used in hydraulic systems, heavy machinery equipment, the automotive sector, construction machinery, and industrial systems.

ORFS T Connectors

• Function: ORFS T connectors create 'T' shaped connections by combining three pipe lines. They provide a secure and leak-proof connection using O-ring sealing technology.

• Material and Durability: ORFS T connectors are made of durable materials (usually steel or stainless steel) and are suitable for systems under hydraulic pressure.

• Areas of Use: ORFS T connectors are commonly used in high-pressure hydraulic and pneumatic systems, heavy industrial machinery, the automotive sector, and maritime applications.

Differences Between NPT, UNF, and ORFS Elbows and T Connectors

• Thread Structure:

  • NPT (National Pipe Tapered): Conical thread structure provides leak-proofing. Generally used in pipe connections.

  • UNF (Unified National Fine): Fine thread structure provides precise and smooth connections. Especially used in industries requiring fine threads.

  • ORFS (O-Ring Face Seal): Provides sealing with O-rings, ensuring secure connections in high-pressure systems.

• Areas of Use:

  • NPT: Plumbing, gas lines, industrial pipe systems, oil and gas transmission lines.

  • UNF: Automotive, aerospace, precision industrial systems.

  • ORFS: Hydraulic systems, pneumatic systems, heavy industrial machinery.

• Sealing:

  • ORFS connections provide sealing with O-rings, NPT threads provide sealing with conical structure, and UNF, having finer threads, are generally used in more precise connections.
