In the production of many different items, companies use gaskets. They are requisite for sealing the flanges of products in the appliance, aerospace, automotive, electronics and military industrial sectors. While several different types of gaskets are available, one of the more popular models is the full face gasket.
Description
Full face gaskets are gaskets that, unlike ring gaskets possess bolt holes. These allow them to cover completely the surface of a flat face (FF) flange. In doing so, they provide security and easy alignment. The material of full face gaskets varies, with different companies producing and/or selling gaskets in their preferred material. Common substances include:
* Neoprene Rubber
* Ethylene propylene diene monomer (EPDM Rubber)
* Non-Asbestos (CNAF)
* Teflon (PTFE)
* Viton
* Neoprene
* Epichlorohydrin (ECH)
* Styrene Butadiene Rubber (SBR)
* Red Rubber ASTM
The gaskets are available in diverse sizes and thicknesses. However, it is always important to remember that the right full face gasket is one in which the outer diameter (OD) is identical to that of the flange it covers.
Applications
The specific application of a full face gaskets depends upon the material, size, and specifications. These gaskets act as sealants for flanges in any of the following applications:
* Plumbing and water services: In both hot and cold temperature applications
* Cold and hot oils
* Gases
* Fuels and coolants with corrosion inhibitors
* Antifreeze
Ultimately, a company or installer chooses the specific kind of full face gaskets they plan to utilize based upon the type of flange in use and the application.
Full Face Gasket
When it comes to matching gaskets and flanges, two major possibilities exist. These are ring and full-face gaskets. Each offers its advantages. However, when the flange is characterized by bolts, the preferred option is a full face gasket. This type provides an ideal sealant by completely covering the flange but allowing the bolts to fit securely into the gaskets bolt holes.
