Perfomance Material Partners

With over 47 years of experience working with high-performance, tight-tolerance sealing applications, Niantic Seal has worked with more than 100 top quality vendors. Our Performance Material Partners include:

Parker Seal

Parker Seal has two Divisions that offer O-ring seals. The O-ring Division is a manufacturer of both standard and custom sized molded elastomeric O-rings, with existing sizes that range from 1/32" ID all the way up to 30" ID. The Techseal Division is a manufacturer of both standard and custom extruded elastomeric profiles that are made into O-rings by cutting the extrusion to length, and then splicing the ends together using a hot vulcanization process. Both manufacturing methods have their own unique attributes to optimize features and benefits, and reduce costs.  Molded O-rings are ideal for both low and high volume manufacture, dependent upon diameter requirements, and there are an abundance of tools in existence to cover a very broad range of standard sizes. The extruded rubber profiles offer an effective and affordable solution for large diameter sized O-rings (too large to be molded), and for unusually large cross sectional configurations. In addition, the extrusion process allows for the production of various hollow shapes, which can provide a multitude of low closure force design options.

Niantic Seal, Inc. is a Parker Seal Sealing Technology Center distributor offering a broad range of customer fabricating capabilities for your individual applications.
