Gasket & Shim

What Gasket & Shim does

Gasket & Shim Industries (GSI) is a Cape Town-based manufacturer and supplier of soft-cut industrial components founded in January 1995. The company manufactures gaskets, shims, seals, O-rings, plate heat exchanger gaskets, EMI gaskets, and filtration products from a broad material range spanning cork, foam, felt, rubber, PTFE, graphite, non-asbestos fibers, and metal alloys (stainless steel, copper, brass, aluminium, beryllium copper). It also fabricates foam components, anti-fatigue mats, sound and thermal insulation, anti-slip materials, and engineered felt products. Manufacturing capabilities include bonding, CNC machining, die-cutting, kiss-cutting (up to 1.8x2.7m), moulding, laminating, slitting, punching, and routing, executed at a single Cape Town facility in Marconi Estate, Montague Gardens.

GSI's business model is project-based B2B sales: customers request quotes via phone, email, contact forms, or WhatsApp, and GSI custom-manufactures components to spec from its material range, which incorporates branded inputs from Klinger, Garlock, Donit Tesnit, and Amorim. Pricing is quote-based with no public list pricing or recurring revenue model. The company serves at least 15 end-use verticals, including steel fabrication, biodiesel manufacturing, bottling, marine, aquaculture, wastewater management, automotive, food and pharma, electronics, nuclear, oil and gas, boilers and steam, and anti-vibration/sound insulation. Delivery is direct from the Cape Town facility to customers globally, although the primary market is South Africa. Certificaciones include ISO 9000, US FDA, BBBEE, Food Quality, and CSD registration, qualifying the company for food/pharma and South African government procurement.

The company is privately held, with no disclosed ownership, management, or funding history. Headcount is in the 11-50 range, consistent with a small specialty manufacturer. There is no evidence of M&A activity, leadership changes, or external capital raise. No software, AI, or digital products are offered.

Broad incumbents

• Freudenberg Sealing Technologies: German global manufacturer of seals, gaskets, and vibration control technology for automotive, oil & gas, food, and pharmaceutical industries. Overlaps with Gasket & Shim's elastomeric seal and gasket portfolio but operates at vastly greater scale and across multiple adjacent product categories.
• EagleBurgmann: Joint venture (Freudenberg + Eagle Industries) supplying mechanical seals, gasket technology, and sealing systems for oil & gas, chemical, power, and water industries. Directly comparable in industrial gasketing and sealing for mission-critical rotating and static equipment.
• ElringKlinger: German-headquartered automotive and industrial supplier offering cylinder-head gaskets, metal-elastomer gaskets, and sealing systems. Comparable in industrial gasket manufacturing with a stronger automotive/OEM tilt than Gasket & Shim.
• Trelleborg Sealing Solutions: Part of Sweden's Trelleborg AB, this is a much larger global sealing-and-gasket business serving aerospace, automotive, industrial, and medical end-markets. Sells overlapping O-ring, seal, and gasket solutions as part of a much broader polymer engineered components portfolio.

Direct peers

• Klinger: Austrian-headquartered global manufacturer of gaskets, sealing products, and fluid control solutions serving oil & gas, chemical, power, and marine end-markets. Klinger is both a direct competitor (industrial gasket manufacturing) and a key material brand partner to Gasket & Shim, making it the most directly comparable peer.
• Lamons: US-headquartered manufacturer and supplier of gaskets, bolts, and engineered sealing products for oil & gas, petrochemical, and power markets. Comparable in product line (spiral wound, sheet gaskets, soft-cut) and B2B industrial quote-based distribution.
• Garlock (EnPro Industries): US-based global manufacturer of fluid sealing and gasketing products (spiral wound, graphite, PTFE, rubber) for chemical, oil & gas, pulp & paper, and power generation. Like Klinger, it is both a direct competitor and a material brand supplied by Gasket & Shim — same product family across overlapping verticals.
• Donit Tesnit: Slovenian manufacturer of soft-cut gasket materials (NAF, graphite, PTFE, rubber composites) serving European and global industrial markets. Directly overlaps Gasket & Shim's core soft-cut and NAF product lines and is also a named material partner.
• Teadit: International manufacturer of gaskets, packing, and sealing products for chemical, oil & gas, power, and food industries. Closely comparable product portfolio (synthetic fiber gaskets, PTFE, graphite) across heavy industrial end-uses.
• Flexitallic: Global specialist in industrial gaskets (spiral wound, RTJ, kammprofile, sheet) for oil & gas, petrochemical, and power generation markets. Overlaps Gasket & Shim's high-end metal and soft-cut product categories and serves the same mission-critical applications.
