Brass Fittings - Vibra Lok


Manufacturing and supplying of Brass Fittings - Vibra Lok has provided us an esteemed position in the Indian market. The joints made by our Vibra-Lok Fittings are virtually indestructible by vibration, shocks and major tube movements, courtesy their strong brass built. Get them from us in varying specifications at affordable prices. We assure to timely deliver every order, owing to our large production capacity and developed logistics.

 

Highlights :

  • 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.

 

Details :

  • Fittings available : 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
  • Material :   
    • 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.
  • Compatible Tubing : All types of seamed and seamless metal tubing Copper, Aluminum, Thin Wall Steel (Bundy or G.M.), Stainless Steel and Glass.
  • Assembly Instructions For Lower pressure Applications :   
    • 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.
  • Assembly Instructions For Higher pressure Applications :   
    • 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.
  • Remark Instructions : All Vibra-Lok fittings can be reassembled repeatedly. New sleeves can easily be added to retain original fitting performance.
