CHAPTER 31 Seals, Packings and Gaskets

Chapter Objectives

Identify the system which is to be made leak proof.
Select the proper seal, gasket, or packing after studying the stiffness of various components, like stiffness of connecting bolts, gasket and members to be joined.
Make a selection of bolts for its class and minimum proof strength.

31-1 INTRODUCTION

Mechanical devices known as seals, packings, and gaskets are used to prevent leakage of fluids, gases from cylinders and cylinder-head in engines, hydraulic pressure cylinder and cover head. These devices also prevent the penetration of foreign matter into the concealed system. Seals are available in various forms and design configurations and the selection of a seal depends on: (1) ...
