2 It provides lubricity superior to Teflon at alower cost!Available in white or burnt orange colors, Vibra-Seal coatingsare highly filled water based liquids that are non-toxic and non-sagging. When dried, they become a resilient, tight clinging andnon-curing sealant. Vibra-Seal coated parts also resist loosen-ing because of the prevailing torque created by the can coat entire parts (frequently done on smaller fas-teners) or can apply Vibra-Seal sealant to a limited band ofSpecificationsResin CoatingAcrylicColorsWhite or Burnt OrangeOn-Part Life4 Years, MinimumToxicityNoneTorque TensionThe tension in the fastener can be reasonably con-trolled by controlling the torque.

3 For any given fastenerthe torque tension relationship can be stated as fol-lows:T = KDFwhere T = Torque, (N m)D = Nominal bolt diameter, in. (m)F = Tension or clamping force, lbs.
