Hydraflex's range of Metal Hose Pump Connectors are integral components designed to handle thermal expansion in piping systems and mitigate vibration from pumps. Being a reputable UK-based manufacturer, Hydraflex tailors these connectors to a diverse clientele both locally and internationally​​.

Construction and Compliance

The construction of these connectors involves high-quality materials like Stainless Steel 316L for the hose and Stainless Steel AISI 304/304L for the braid. The connectors are capable of withstanding a temperature range of -269°C to +600°C, and are available in sizes ranging from ¼” NB to 16” NB. They are manufactured following the ISO 10380:2012 standards, ensuring compliance with the Pressure Equipment Directive (PED 2014/68/EU). All units undergo a 100% pressure test at 1.5 times the design pressure, emphasizing their robust construction and compliance to industry standards​​.


These connectors find extensive application in:

  • Building Services
  • HVAC-R Piping Lines
  • Pump Connections
  • Vibration Producing Systems
  • Industrial Process & Applications
  • Steam, Chemical, and Gas Connections
  • Ultra-High Vacuum and Exhaust systems​​.

Benefits and Features

With the primary function of absorbing lateral movements (thermal expansion) in pipelines and reducing vibration from pumps, these connectors enhance the operational efficiency and longevity of the piping systems. They are also engineered for easy installation and maintenance, thereby providing a cost-effective solution for various fluid transfer needs​​.
