Sanitary Gaskets 

Newman Sanitary Gasket Company (NSG) has exclusively served high purity process industries since 1973. Starting with the food & beverage industry, NSG has since expanded into pharmaceuticals, biopharmaceuticals, among others, and has become a leading supplier of sanitary gaskets around the world. Our sanitary gaskets include a variety of types, such as tri-clamp sanitary gaskets, envelope gaskets and schedule 5 gaskets. To meet the needs of NSG customers we have created a full range of proprietary materials and processes for our sanitary gaskets and other seals that meet the most critical demands of our customers.

Sanitary and hygienic gaskets are often the most overlooked aspect of processing equipment. A sanitary gasket made from inferior materials or manufactured poorly can lead to dramatic and unforeseen consequences. Although the main purpose of the sanitary gasket is to seal, it is often expected to correct imperfections, such as misalignment, damaged components and improper installation. NSG’s robust materials and designs ensure that the customer’s manufacturing processes will run smoothly and the products remain pure.

All of NSG’s high purity sanitary gaskets and materials are designed to protect the product, process and the consumer.
