Key Characteristics

Standard: Manufactured according to DIN 2353 (German Standard) and ISO 8434-1 (International Standard) for hydraulic fittings, which specify the dimensions, thread types, and materials for the fitting.

Connection Methods

  • 24° Compression Cutting Ring Seal: One end uses a 24° compression (bite-type) cutting ring that compresses onto the tube, forming a mechanical seal ideal for high-pressure hydraulic systems.
  • UN/UNF Thread Stud Ends with O-Ring Sealing (ISO 11926): The other end features a UN/UNF (Unified National/Unified National Fine) thread stud end, designed according to ISO 11926. It utilizes an O-ring as the sealing element, ensuring a highly reliable and leak-resistant connection. This type of connection is particularly well-suited for softer counter materials, such as aluminum alloy housings, preventing damage to the mating surface. Additionally, it is highly effective for gas applications, offering secure sealing and preventing leaks.

Material

Typically made from carbon steel, stainless steel, or other alloys depending on the application and fluid compatibility.
