Selection Guide for Metal Detectable
Sanitary Gaskets and O-Rings

Sanitary Gaskets and O-Rings used in food, beverage and pharmaceutical production equipment can be damaged during installation or deteriorate over time due to exposure to continuous vibration, extreme temperatures and corrosive chemicals.

Platinum Cured Silicone Gaskets
and O-Rings—The Basics

Platinum cured gaskets and o-rings (VMQ) can often be the best choice for food, beverage, pharmaceutical and biotechnology production applications.

What makes an O-Ring Food Grade or Food Safe?

The material that an o-ring is made from is the principle determining factor on whether it can be identified as food grade or food safe.

Metal Detectable O-Rings – The Basics

The use of metal detectable o-rings is a very effective method for locating rubber fragments of seals and gaskets that have migrated into the process stream.

Metal Detectable O-Rings help meet government regulations regarding foreign material contamination

Regardless of government regulations it is important that production processes are designed to keep foreign materials from entering the process stream and critical that a system is in place to detect contaminated product and prevent it from leaving the production facility.

Metal Detectable Sanitary Gaskets are Important Contributors to Food Safety

An important aspect of food safety is keeping foreign materials from contaminating the food product. Because sanitary gaskets and other elastomeric sealing components are a potential source of contamination, it is important to take the necessary steps to reduce this risk.

The rationale for using Teflon® Encapsulated O-Rings

FEP-/PFA-encapsulated o-rings combine the outlasting chemical resistance of PTFE with the sealing force of an elastomer. In general, Teflon® Encapsulated O-Rings should be applied standard elastomers do not provide sufficient chemical resistance.

Unitized Sanitary Gaskets

Unitized sanitary gaskets are a novel approach to solving some of the problems encountered with Tri-Clamp sealing applications, particularly those involving aggressive environments.
