What Marco Rubber & Plastics does

Marco Rubber & Plastics (now operating as Marco Sealing Solutions) is a US-based, privately held specialty distributor of elastomer sealing components founded in 1980 and headquartered in Seabrook, New Hampshire. The company supplies O-rings, gaskets, performance seals (spring-energized, glide, backup rings), custom-molded components, and high-performance plastic parts across more than 3,000 material formulations covering FKM, FFKM (proprietary Markez® line), PTFE, silicone, EPDM, HNBR, NBR, FEPM, polyurethane, and specialty compounds. It serves highly regulated end markets including semiconductor, aerospace and military, oil and gas, chemical processing, food/water/life sciences, and electronics (EMI/RFI shielding), with regulatory compliance spanning ISO 9001:2015, FDA 21 CFR 177.2600, USP Class VI, NSF-61, WRAS, KTW, ACS, 3-A Sanitary, REACH, RoHS, and MIL-I-45208/AS9120.

The business operates a dual-channel go-to-market: an e-commerce storefront for standard catalog O-rings and seals with listed pricing and same-day shipping on in-stock items, paired with assisted direct sales via phone and quote requests for custom solutions. Revenue is generated primarily through one-time product sales, with custom solutions and material formulation services priced per quote; engineering design support and custom compound development are typically provided at no additional charge, positioning the company as a technical solutions partner rather than a commodity catalog vendor. Reported operational metrics include a 99.9% product acceptance rate and 93%+ on-time-in-full delivery, supporting a service-led value proposition.

Since 2021, the company has been owned by private equity firm Align Capital Partners and has executed a sustained buy-and-build program, completing at least seven add-on acquisitions (Premiere Precision Components 2021, Anchor Rubber 2022, Ipotec 2022, American Seal & Packing 2023, Allied Metrics 2024, Colonial Seal Company 2025, Pride Seals 2026) to broaden product range, customer base, and geographic footprint. Operations now span New Hampshire (HQ, ISO 9001:2015 by NQA), Florida (ISO 9001:2015 by PJR), and Santa Ana, California (post-American Seal & Packing acquisition), with additional sites added through subsequent deals. In 2025 the company rebranded from Marco Rubber & Plastics to Marco Sealing Solutions to reflect its evolution into a broader sealing-solutions platform.
