Soft Seal Connectors – The ultimate hydraulic connectors

Soft seal connectors are a modern development in hydraulic connectors, intended to address the most common issues with older designs, including leakage and the effects of vibration. They’re also designed to work in much higher pressure systems, to meet the growing needs of a wide range of applications across different industries. Soft Seal Connector Definitions Elastomer noun (Chemistry) An elastic substance occurring naturally, as a natural rubber, or produced synthetically, such as butyl rubber or neoprene. Elastomeric adjective (Chemistry) A part that has an elastic quality about it, or one that uses an elastomer. Soft seal, or elastomeric connectors use a soft seal to complete the joint, resulting in a leak free and vibration resistant joint. The seal is usually an O-ring. Advantages of soft seal connectors Soft seal connectors have a number of advantages, including: They are positive sealing Resistant to vibration Very high pressure capability Easy and quick to assemble, which is important in high-volume production Disadvantages of soft seal connectors The O-ring in soft seal connectors may harden with heat or soften with incompatible system fluids, so ...

Hydraulic connector thread forms and their applications

If you’re new to the world of hydraulics, it can seem difficult to gain an understanding of the many hydraulic connectors available today. In this series of articles, you’ll learn about the different types of hydraulic connectors and their key differences, which will assist in making some sense of this complex subject. Factors affecting development of hydraulic connectors Two factors have influenced the development of hydraulic connectors: 1: A reluctance to adopt industrial standards between countries Many of these connector types were developed during the 20th century; a time of fierce industrial competition. Co-operation between the major industrialised countries was limited for many years due to conflict. 2: The evolution of hydraulic systems Hydraulic systems have changed a great deal in a short period of time. Driving this change is the gradual increase of the desired machine output force, which is seen as a pressure increase. In the previous series of articles introducing the three types of hydraulic connectors we discussed three principle types of connectors: Tapered threads Metal seal connectors Soft seal connectors Each major industrial region has developed ...
