A hydraulic compression tube fitting is made up of compression nut, inner compression ring also ferrule(one or two ferrules type), and tube adapter body.
Different standards of Compression tube fittings:
Standards | Thread | Sealing Way | Tube Type | ISO 8434-1 Interchangeable | Country |
DIN 2353 | Metric | 24°cone | Metric | Yes | Germany |
JIS B2351 | Metric | 24°cone | Metric | Partly yes. The pressure rating is different. | Japanese |
SAE J514 section 2 | UNF | 24°cone | Inch | No | USA |
*DIN 2353 standard is non-soldering compression fittings with cutting ring-complete fittings and survey. It is interchangeable with ISO 8434-1.
*JIS B2351 is based on ISO 8434-1 standard. It is metallic tube connections for fluid power 24°compression fittings.
*SAE J514 standard section 2 is about flareless compression fittings.
Types of ferrule tube fittings connection as pictures:
Tube to Tube, Tube to Female Pipe, Tube to Male Pipe, Tube to Port Connectors, Tube to AN Tube, Tube to SAE O-ring boss, etc. There are different shapes like straight, elbow, tee, cross, bulkhead, adjustable locknut.

Tube Compression fittings are commonly designed and manufactured for leak-free connections in process instrumentation and industrial piping system applications such as chemical, oil, petrochemical processing shipbuilding, offshore, metallurgy, nuclear power generation, heavy industries field, Brake Lines etc. Therefore, for working in these high-temperature, high-pressure, harsh conditions, hydraulic compression fittings need to be robust enough. Compression fittings at Jiayuan are made of top-grade steel and stainless steel (of your option) that differ in characteristics. The only thing you need to do is find a series of fittings that meets your hydraulic or pneumatic system specifications and then let us know. Various brands of hydraulic tube compression fittings are all interchangeable with Jiayuan's compression fittings.
