Over 50 Years of Supplying MIL-SPEC Connector Gaskets and Shielding Products to Defense Contractors and Industry Leaders


We have been supplying MIL-SPEC connector gaskets and shielding products to defense contractors and industry leaders for over 50 years. Our modern plant is equipped with facilities for tool design and manufacturing, product design and engineering, extrusion, molding and other production equipment. Additionally we have raw material and finished products testing facilities. Our inventory of substantial stocks of raw materials enables us to put most jobs into production quickly.

M83528.com was launched in 2016 as the online connector gasket distribution source for Ja-Bar Silicone Corporation. In 1985, with compounds developed to meet or exceed the competitions, Ja-Bar qualified for what was then referred to as MIL-G-83528, now known as MIL-DTL-83528. We maintain QPL status for these materials, and have added essential variations to these compounds to accommodate both the military and commercial markets' sealing, shielding, and survivability needs.

We have in-house capability to compound our own materials, design and produce our own dies and molds, and manufacture needed components. We are not dependent on outside sources which enables us to maintain complete control of every job. This assures quality products, shorter lead times, and on time delivery at very competitive prices.

Our specialized staff maintains a thorough and careful program of quality control and inspection. We are fully qualified to test and certify that our products meet critical specifications. M83528.com is dedicated to providing service and products that give our customers complete satisfaction.

Customer service does not stop after the sale is made. If you require after-sales assistance, you will find we are immediately responsive to your needs.
