RUBBERIZED CORK GASKETS AND FRAME  
In our ongoing efforts to reduce component cost, time and labor in industries, we have come up with a unique idea to manufacturer Rubberized Cork Frames / Gaskets and Components. We manufacture Cork frames of any shape and type; it may be Rectangle, Square, Round, ‘ L ` type or any oblong shape. Cork frames manufactured by us are completely leak proof as the same are made JOINT LESS contrary to the one, which are usually being offered with minimum two to four joints.
We are at present supplying these Frames or ready to use Gaskets to our Customers strictly as per their required Standards. We are also manufacturing complete set of Cork Gasket for Transformer Industries, which can include as many as 52 Gasket of different Shape and Size.
   
Tips for correct tightening sequence.
It's good practice to tighten a number of bolts from the middle towards the outside of a group in three steps. Initially just until you feel some resistance, then about half the final torque, and finally to the correct torque value.
