Our Mission

We serve original equipment manufacturers (OEM's) in all industries. At Darcoid Nor-Cal Seal we have a saying, “a seal is inexpensive unless it fails.” We are committed to ensuring your business and product are not compromised by "bad" seals. Our quality assurance program is best in class, inspecting over 40 million seals a year. Aligning closely with our customers' business process, we manage supply chain programs and ship over 80 million seals a year. We maintain close relationships with our technical partners and suppliers with proven history of consistency and integrity of their compounds and materials.

Though relatively small, a seal has a large impact on product performance and quality.  Our core values of respect, honesty, and integrity carry though in our seals.

Crest Technology, located in Austin, Texas, provides semiconductor fabs with the most comprehensive cross reference database of confirmed OPM/ second source parts. Our value engineering of critical spare parts will enhance tool performance and extend component lifetime.
