A Quick Comparison between Full Face and Ring Type Gaskets

23 August 2021

Every part of a machine or fixture plays a vital role to ensure that they can work great. One specific component that can be truly helpful in maintaining the operations of machines and fixtures is the gasket.

Gaskets are mechanical seals that can fill the gap between the mating surfaces of a machine or fixture. Through these mechanical seals, any instances of leakage can be prevented, even if the surfaces of the machines or fixtures will be exposed compression during their operations. Since leaks are eliminated, the internal components of machines or fixtures will be safe from sudden infiltration of liquid or gas elements.

Since industries often conduct different operations in varying places and conditions, they must maximise gaskets that are compatible with their applications. Hence, gaskets are typically created from a wide array of materials. They likewise come in various types. Two of the most common types of gaskets are full face and ring type gaskets.

Full Face Gaskets

Full face gaskets are gaskets that can entirely cover the face of a flange. These gaskets typically have a similar outer diameter measurement as the flange, allowing them to fill the flange. And for them to cover the flange completely, these gaskets normally contain some holes so that bolts can be secured right into them. These holes likewise allow these gaskets to be positioned conveniently. All the features of the full face gaskets make them great for preventing dirt particles from entering between the bolting surfaces.

When specifying for full face gaskets, one must identify the needed inside diameter (pipe bore) and outside diameter (flange outside diameter). Other requirements that are needed to specify full face gaskets are bolt circle diameter, number of bolt holes, and gasket thickness.

Ring Type Gaskets

Ring type gaskets, on the other hand, are typically located inside of the securing or flange bolts. They can likewise be positioned and sit around the pipe bore. Unlike full face gaskets, ring type gaskets do not have bolt holes. Their composition, fortunately, makes their installation easier since joint disassembly is not needed. These gaskets even require less material and less cutting. The features of ring type gaskets make them great for petroleum-related applications, pipes, valves, and other related things.

Full face gaskets require numerous elements for them to be specified. Ring type gaskets, alternatively, only need three things: inside diameter (pipe bore), outside diameter (raised face outside diameter), and gasket thickness.

Both full face and ring type gaskets can be effective in sealing the joint. But for them to be effective, they must be installed correctly and maintained regularly.
