Studies of tubing failure resulting from vibration have shown this failure in the majority of cases to be caused by
fracture of the tubing at the point of connection.These fractures are the result of either fatigue of the metal caused by constant vibration and shock, or of
distortion of the tube in making the joint.
The Pioneer Vibra-Lok fitting makes a joint that is virtually indestructible by vibration and will withstand considerable shock and major tube movement. In the
Vibra-Lok fitting. The tubing is cushioned against all such damage by the elastic sleeve.
The sleeve of the Vibra-Lok fitting is made of a special composition Buna-N elastic sealing materials. This elastic sleeve forms a cushion between tubing and
fitting. It assures a positive, pressure tight seal, permits the tube to flex back and forth in the fitting. Seal design compensate for tube misalignment and
tube surface defects during assembly. Special Vibra-Lok sleeves resist deterioration and retain flexibility over a wide temperature range.

Straight Connectors, Stud Elbow, Branch Tee, Run Tee, Female Stud, Union-Straight Elbow Tee - Available in above tube size & thread size combination. Maximum Working Pressure :1000 psi
Elbows and Tees : Brass Forgings - S.A.E. Ca377 Connectors, Unions, Nuts : Stress relieved bar stock - S.A.E. 360 Sleeves : Special elastic sealing material Buna-N used for temperatures from sub-zero to 275oF / 135oC. The sleeve has extreme resistance to deterioration by oil and gasoline. High temperature sleeves made of Viton for use from sub-zero to 450oF / 232oC. Sleeves are compatible for gasoline, oil, diesel fuel, lubricants, vacuum, air and water service.
All types of seamed and seamless metal tubing Copper, Aluminum, Thin Wall Steel (Bundy or G.M.), Stainless Steel and Glass.
Slip tube nut and sleeve over tube. Insert tubing in fitting body as far as it will go and tighten nut until stop is reached.Cut the tube cleanly and squarely removing all burns. There is no danger of overt-tightening. The elastic sleeve ordinarily will extrude slightly around the tube at the end of the nut. This extrusion further aids in isolating the tube from the nut.
Consult pressure chart to determine if tubing should be belled for your particular application. FIG A. Slip the nut and sleeve over tubing. The sleeve should be positioned near end of tubing Applications just behind the surface to be belled. FIG. B. Bell tubing with standard 45 o flaring tool or 90 o punch. The size of bell should be approximately that shown in FIG. C.
All Vibra-Lok fittings can be reassembled repeatedly. New sleeves can easily be added to retain original fitting performance.
