Manufacturing Capabilities
Our Pittsburgh-area facility integrates extrusion, molding, die cutting, and secondary fabrication. This vertical integration reduces lead times, improves repeatability, and supports PPAP documentation when required. We help teams finalize profile geometry, validate durometer and compound, and prepare tooling that meets cost and tolerance targets for production.
Typical deliverables include custom profiles, edge trim, grommets, O-rings and cord, sponge rubber shapes, bumper stops, and precision die-cut gaskets. We also handle assembly and adhesive bonding to ship ready-to-install components.
We evaluate application risk factors—thermal cycling, joint movement, chemical exposure, and installation variance—then tune profile geometry and durometer to keep sealing force inside the design window over service life. Tooling is engineered for stability across long runs with attention to splice quality, surface finish, and dimensional control.
Continuous improvement is built into our release process. We capture feedback on wear patterns and leak points, iterate profiles or compounds where needed, and update documentation to lock in wins. When customers scale, we scale with them.
About National Rubber Corporation
Our Story
National Rubber Corporation started in 1997 as a small, ambitious shop with one goal: make rubber parts that industries demanding precision could count on. Skilled people and steady investment grew it into a full-service manufacturer with customers in aerospace, automotive, defense, food and dairy, healthcare and industrial manufacturing.
Whether you need a simple part or a multifaceted industrial or mechanical part, we will work with you to design, prototype and manufacture custom parts to meet your exact specifications. We have the ability to customize your products to accommodate any size, shape or applications. What's more, we've got the capacity, the manpower and the determination to deliver quality products on time, every time.
Today we work from a 68,000 sq. ft. facility just off I-79 south of Pittsburgh, with extrusion, molding, cutting, fabrication and compounding under one roof. Our third decade in business comes with the same promise we started with: we will be there when you need us.
