Since 1968, Spec Rubber has stood for more than rubber products — we represent American grit and quality.
From our home in Alabaster, Alabama, we’ve grown into the nation’s largest domestic industrial rubber gasket manufacturer.
Made in Alabama, our rubber gaskets are known for outlasting, outperforming, and outclassing the competition.
Every rubber component we produce is proudly made domestically for the industries that keep this country moving.
Spec Rubber products meet all Buy America, Build America Act (BABA) standards. No shortcuts, no exceptions.
We build custom rubber gaskets that stand up to the toughest conditions — because lives, infrastructure, and reputations depend on them.
We’ve spent 50+ years mastering molded rubber products, and we’re just getting started.
With 50+ presses, redundant systems, and a specialty rubber production facility in Alabama, we deliver molded components that are built right and built to last. Whether you need standard parts or custom solutions, we’ll meet you where you are.
From engineering challenges to compliance requirements, we deliver high-performance rubber solutions built to exceed expectations. Here’s how we do that:
