August 15th, 2016 - Sometimes when the pressure gets to be too much, a breather is needed. The same is true within custom cable design. Breather tubes integrated within cable design not only enable the release of pressure, heat, or steam, but can also facilitate the transfer of gas and fluid.

Another key function for breather tubes incorporated into wiring harness applications is to bundle inner components. This use allows for the separation of internal cable components in addition to providing protection and a resulting abrasion resistant cable.

Key criteria are highlighted within the Extreme Materials – Robust Performance from Cable to Connector white paper released by connector and cable assembly manufacturers, Northwire and LEMO, for breather tube selection including an understanding of the demands of the cable application, construction features, and material selection.

Designing custom cable which exceeds the demands of extreme environments, Northwire provides breather tubes in a wide range of material types, sizes, and durometers that offer elevated protection against high heat, pressure, oil, water, chemicals, flame, and abrasion.

With the ability to prevent damage to the cable assembly caused by extreme temperatures and pressure while contributing additional function to cable systems, breather tubes are intrinsic within cable design for applications including:

  • Automotive

  • Food and Beverage

  • Medical Wire and Cable

  • Fiber Optic Cable Systems

  • Dental Equipment

  • Liquid or Gas Transfer

  • Oil and Gas Fields

  • Factory, Automation, and Industrial Cable

  • And More

Asking the right questions and providing the right recommendations, Northwire SME’s consider every factor contributing to and challenging the application’s performance. Ensuring high reliability and safety, NWI Subject Matter Experts provide material recommendations for breather tubes including:

  • PE: Polyethylene

  • Nylon

  • PVC: Polyvinyl Chloride

  • PUR: Polyurethane

  • PTFE: Fluoropolymers

As connectivity partners, cable engineer Northwire and custom connector manufacturing leader LEMO offer complete and fully integrated cable and connector solutions. With configurations designed for the specific industry and application, LEMO fluidic connectors provide precise mating with Northwire’s breather tube cable.

Fluidic connectors are utilized within many applications requiring precise, dependable fluid connections. Detailed application assessments by LEMO connector engineers take into account the application’s unique requirements such as the need for water resistance. For example, LEMO’s REDEL 1P plastic fluidic connector for single fluidic contacts aligns well with applications within medical or dentistry equipment. This connector is a monotube type and primarily intended for use with air or inert gas. (Find more information about LEMO’s 1P plastic connector on page 16 of LEMO’s online P series catalog.)

Single fluidic contacts as well as hybrid configurations are also available within LEMO’s metal B and K series. Multi fluid, mixed fluid, LV, and connectors combining fluidic and signal contacts are available for specific applications.

Multi-functional tubing is just one of many cable and wire variables covered within Part IV of Northwire and LEMO’s collaborative white paper series.
