ENGINEERING AND DESIGN
• QUICK CONNECT, simply push tubing in, no tools. Saves up to 75%
of assembly time of standard compression fittings.
• QUICK DISCONNECT, hold two fingers on insert and pull tubing
out, no tools required.
• REUSEABLE, connect and disconnect numerous times.
• FULL FLOW DESIGN, provides up to 60% more flow area than
conventional fittings with internal tube supports.
• POSITIVE SEAL, no leaks. After tubing is inserted, seal is made.
• VERSATILE, BunaN “O” rings standard. Other materials of “O” rings
available.
• SECURE TUBE RETENTION, pulling on tubing only serves to

expands the insert. Pulling back on the tube only tightens the
grip as the insert moves onto the camming surface (4). Pres-
sure through the tube also serves to tighten the grip. The tube
bottoms against a positive tube stop (5) in a cavity providing
tube support to prevent leakage.
When tubing (1) is inserted
into the fitting, it first passes
through the gripping teeth
(2). Just beyond the gripping
teeth is the o-ring (3) which
provides the leak proof seal
against the OD of the tube.
The gripping teeth grab the
tube, which
• CHOICE of convenient swivel of economical stationary elbows and tees.
• STRAIGHT CONNECTORS have interior hex for Allen key tightening where space is limited...no need to use a wrench.
• PRE-APPLIED TEFLON ® based pipe sealant on all male pipe threads, saving customer additional labor.
• METRIC SIZES AVAILABLE: Metric tube sizes from 2mm through 12mm in both standard NPT and metric pipe sizes are avail-
able on a special order basis.
• WORKING PRESSURE:
The fitting is suitable for use up to the maximum working pressure of the plastic tubing used. For soft copper tube, a maximum work-
ing pressure of 750 PSI is recommended. Also suitable for vacuum service.
• WORKING TEMPERATURE:
-100F to 2000F (other ranges available on request).
• PIPE THREAD : NPTF with Teflon ® based sealant pre-applied.
