Automatic Sealing Connectors

TQC can supply a standard range of automatic sealing connectors that can be used in a number of applications including leak testing and pressure testing of parts. There are both internal bore and external bore variants of these leak test connectors available for leak tight connections to internal bores from 10mm upto 75mm and from 3mm upto 71mm outer bore diameter sizes.

Datasheets on these standard leak test connectors are linked below –

Internal automatic connectors

External automatic connectors

The majority of automatic leak test connectors are single acting and use a single actuation port, once actuated a piston act on a seal then expands the seal on the component. Connectors are supplied with a central test port which can be blanked off as necessary. Double acting variants are available and mainly used for high throughput, short cycle time applications.

TQC have over the years developed special leak test connectors based around the standard connectors, generally a solution can be found for any application!

Typical examples of when a special connector is required:

  • Part geometry does not suit the standard connector, TQC can modify the design of the ‘nose’ of the connector to suit (shorter or longer)
  • Test pressures exceed the valid standard connector values, TQC can supply connectors with a gripping mechanism that secures the connector to the test part
  • Multiple ports in close proximity, TQC can design a multi connector to suit the application
  • High speed application, TQC can provide a double acting connector so that the seal is positively released from the test part
