Mercer Gasket and Shim

What Mercer Gasket and Shim does

Mercer Gasket and Shim is a privately held, single-facility custom manufacturer and authorized distributor of industrial sealing, gasketing, shim, and hose products, founded in 1919 and operating from Bellmawr, New Jersey. The company's core offering is build-to-print custom fabrication of metallic gaskets (including jacketed, Kammprofile/MerKamm proprietary designs, and spiral wound), non-metallic gaskets (rubber, PTFE, carbon/graphite, ceramic fiber, extruded/molded), O-rings, metal shims, expansion joints, mechanical packing, paddle/spectacle blinds, heat exchanger tube plugs, mechanical seals, and solar slip sheets, plus authorized distribution of premium third-party brands including Durlon, Victor Reinz, Garlock, Thermoseal, Gore-Tex, Kroll & Ziller, Nilos Rings, Vulcan Seals, and Texcel. Manufacturing is anchored by six in-house cutting technologies (Trumpf Trulaser 1030 fiber laser, large-format waterjet, digitally controlled knife, flatbed die, flash, and CNC router), supported by CAD design and computerized reverse engineering, and protected by ISO 9001:2015, UL-Registered Firm, SBE, and compliance with ANSI, ASME, ASTM, DOT, FDA, Mil-Spec, and RoHS standards.

Mercer sells on a quote-based / RFQ model with 24/7/365 emergency on-call availability and rush service tiers, distributed across direct phone/email sales, its own e-commerce storefront at mercergasket.com, and contract-manufacturing engagements. End markets include oil refining, petrochemical processing, conventional and nuclear power generation, aerospace and defense, electric vehicles and renewable energy, industrial OEMs, and rooftop solar installers. Go-to-market blends inside sales, sales-led enterprise field engagement, and channel partnerships, supported by content marketing, SEO, downloadable technical resources, and HubSpot-powered lead capture.

The business is small (11-50 employees), American/New Jersey-owned, and tightly held, with no disclosed revenue, funding events, or ownership transitions. Strategic posture emphasizes incremental capability investment (recent Trumpf laser installation), vertical diversification (EV/renewable, solar slip sheets), and expansion of the authorized-distributor portfolio rather than scale-driven growth, M&A, or external capital.

Core offering

Mercer Gasket and Shim is a custom manufacturer and authorized distributor of industrial sealing components, including metallic and non-metallic gaskets, O-rings, metal shims, mechanical packing, expansion joints, mechanical seals, solar slip sheets, and industrial hoses. The company also operates six in-house precision cutting services (laser, waterjet, knife, flatbed die, flash, and CNC router) used both to produce its own products and offered as contract fabrication.

Product overview

Mercer Gasket and Shim operates a single, integrated custom manufacturing business rather than a platform-plus-modules SaaS architecture. The portfolio spans two interlocking categories: (1) a broad in-house product line of industrial sealing and fabrication components — including Metallic and Non-Metallic Gaskets (with sub-types such as Jacketed, Kammprofile, Spiral Wound, Rubber, Carbon & Graphite, Ceramic Fiber, Extruded & Molded, and PTFE), O-Rings, Metal Shims, Custom Washers, Mechanical Packing, Solar Slip Sheets, Expansion Joints, Custom Paddle and Spectacle Blinds, Heat Exchanger Tapered Tube Plugs, and Mechanical Seals — and (2) six precision in-house Cutting Services (Flatbed Die, Knife, Laser, Waterjet, Flash, and CNC Router) that manufacture the products above and are also offered as contract services. The portfolio is rounded out by authorized distributor relationships for branded lines including Kroll & Ziller Seals, Nilos Rings, Vulcan Seals (mechanical seals), Texcel Industrial Hoses, and gasket materials from Durlon Sealing Solutions and Victor Reinz.

Products and services

• Metallic Gaskets Custom metal and metal jacketed gaskets fabricated in any metal from aluminum and copper to Inconel and titanium, in any thickness, with unlimited pressure capabilities and wide chemical resistance. Includes flat solid, profiled/serrated, corrugated, spiral wound, shims, seal strips, and heavy cross-section styles for industrial OEMs, refining, and power generation customers.
• Jacketed Gaskets Highly durable jacketed gaskets that combine superior temperature resistance of a metal jacket with optimal sealing performance of a soft filler, available in single jacket, double jacket, double jacket with double shell, double gasket corrugated, and French style configurations for heat exchangers, process piping, and high-temperature industrial service.
• Kammprofile (Camprofile) Gaskets Semi-metallic gaskets consisting of a metal core serrated on each side covered with a soft filler bonded to each face, ideal for standard pipe and heat exchanger applications. Available in proprietary MerKamm, MerKamm IG, and MerKamm LG styles in a wide range of metals and sealing elements including flexible graphite and PTFE for nuclear, petrochemical, and power generation customers.
• Spiral Wound Gaskets Custom spiral wound gaskets composed of a steel centering ring, a spiral wound sealing strip, and an inner ring made of special steel, created by winding alternating strips of metal and filler material. Ideal for applications with fluctuating temperature and pressure and low seating stress in refineries, power plants, and chemical processing.
• Non-Metallic (Soft) Gaskets Gaskets, die-cut parts, and strips fabricated from a wide range of soft materials including fiber, rubber, graphite, and PTFE. Includes standard pipe flange, custom, encapsulated, envelope, laminated, molded/extruded/vulcanized, boiler, manhole, glass fiber tape/rope/cord, and sponge product styles for general industrial sealing applications.
• Rubber Gaskets Custom rubber gaskets die cut or CNC flash cut from Butyl, EPDM, Natural (Pure Gum), Neoprene, Nitrile (NBR/Buna-N), SBR, Silicone, Vinyl (PVC), and Viton, available in both solid and sponge (open or closed cell) forms for general industrial sealing.
