About

The I.G. Marston Co. - Since 1844

The I. G. Marston Co. was founded in Boston in 1844 as a manufacturer of hand- and foot- powered table saws. The company diversified, and began manufacturing precision non-metallic (leather) flexible washers in the mid 1870's. After more than twelve decades of servicing our customers from the Boston address, we moved in 1968 to our present 15,000 sq. ft. facility in Holbrook, MA, where and we continue to be the leading washer manufacturer of non-metallic washers and gaskets.

While we continue to take advantage of technological advances in machining and office systems to expand our precision washer capabilities, our philosophy remains the same: to provide our customers with a quality product, to exact specifications, delivered on time and at an honest value.

Non-Metallic Washers - In-Stock to Custom

I.G. Marston Co. currently offers non-metallic washers available from stock in over 125 sizes in the following materials:

  • Nylon

  • Neoprene

We also stock MS51859, NAS549 and NAS1515 sizes, and can manufacture MS, NAS and other sizes not listed.

Custom Specifications for Washers and Gaskets

Various parts are welcome for quotation, as we can make tooling to accommodate your needs. You may choose from our inventory of over 2,000 special washer dies, beginning with inside diameters of .025" and outside diameters of .060". Our products are made from an extensive list of non-metallic materials in thicknesses from .001" to .125". We are capable of producing a variety of specialized parts, including precision washers, gaskets, insulators, seals, discs and more.

Manufacturing Processes

For high-density materials such a nylon, fibre and PVC we employ a high-speed custom stamping spacing process, and use a die-cutting process for softer materials such as rubber, cork and felt. The integration of these two processes within our facility allows us to make our products in the most cost effective manner with the strictest quality assurance.

Quality and Customer Satisfaction

Our Statistical Process Control (SPC) System unfailingly monitors our production output to ensure that the first piece and the last piece of each run are both of first-rate quality. The I. G. Marston quality system is ISO 9001: 2008 certified, and all our production personnel are trained to follow strict quality procedures.

I.G. Marston has customers across the United States and around the world, in many different industries. Through carefully maintaining our standard of excellence as well as introducing new technologies, processes and materials, we have had satisfied customers since 1844, and plan to provide innovative and dependable solutions to our customers' needs for many years to come.
