What Colonial Seal Company does
Colonial Seal Company, founded in 1994 and headquartered in Holiday, Florida, is a small ISO 9001:2015-certified U.S. distributor and light manufacturer of sealing products serving industrial OEMs, industrial distributors, and end-user companies across food & beverage, pharmaceutical, and government/defense applications. The company's portfolio spans custom metal-cased seals (1.2" to 68" OD), gaskets, hydraulic seals, mechanical seals, rotary shaft seals, oil seals, V-seals, O-rings, spring-energized seals, Speedi Sleeves, and Inpro/Seal bearing isolators, with seal lip materials covering NBR, Viton, PTFE, silicone, leather, and HNBR and casing materials in stainless steel, mild steel, and brass. Its core technical proposition is the ability to engineer custom seals, including replacements for discontinued OEM styles (Garlock, SKF, GACO, Elring Klinger, Trostel), supported by engineering guidance on pressure, load, media, and case design.
The business model is sales-led and quote-based, with no public pricing, no tooling charges, no minimum order quantity on custom designs, and a typical five-business-day turnaround. Customer acquisition is driven by direct phone outreach (1-800-564-2201), website quote requests, technical content marketing, and social channels. The company is registered as a Vietnam-Era Veteran-Owned business, which supports eligibility for government and defense procurement set-asides.
On June 3, 2025, Colonial Seal Company was acquired by Marco Rubber & Plastics, a portfolio company of Align Capital Partners, integrating it into a PE-backed sealing solutions platform that has been executing a series of add-on acquisitions. The transaction positions Colonial Seal's custom and replacement-seal capabilities, regulatory qualifications (FDA 21 CFR 177.1550 / 177.2600, USP Class VI), and Southeast U.S. footprint as a complement to Marco's broader product and supply chain reach.
