  2. Fast disconnect: Hold the collet collar with two fingers and pull out tube. No tools required.
  3. Reusable: Can be connected and disconnected several times.
  4. Reliable sealing: Using recommended tubing, full sealing is guaranteed.
  5. Versatility: Buna-N Oring standard. Viton and others available per request. Secure Tube Retention. Pulling on tubing only serves to tighten the connection.

The brass captive eyelet with extended length is floating and has a machined top end radius for easy instal-lation of tubing. All male threads have a pre-applied Teflon based pipe sealant to provide for easy assembly and leak proof seal.
