DENSIQ

What DENSIQ does

DENSIQ is a Nordic-leading manufacturer and supplier of sealing technology to the process industry, headquartered in Västra Frölunda, Sweden, with operational subsidiaries in Norway (DENSIQ AS, offices in Sandnes, Skien and Bergen) and Finland (DENSIQ OY, Oulu). Founded in 1918 as Specialmaskiner AB and operating under the DENSIQ name since 2017, the company delivers a unified portfolio of sealing products — seals and gaskets, mechanical seals, expansion joints, mechanical radial seals, and support products (lubricants and composites) — together with a comprehensive service offering that includes leak sealing during operation, on-site machining, hydraulic bolt tensioning, valve testing, retubing, wrapping, inspection, installation, technical training, and engineering/material testing and prototyping.

The company's product portfolio is anchored by proprietary technology including the patented Pipe Wrapping Technology for permanent pipe reinforcement, the EU EcoLabel-certified EcoLube IQ thread lubricant (the first of its kind on the market), and the DENSIQ Sealing Technology Platform that delivers technical documentation and selection tools across multiple process-industry verticals. DENSIQ operates as part of the DENSIQ Group alongside sister companies DEPAC (Austria-based mechanical seal manufacturer, acquired October 2023, products in 30+ countries) and VM Kompensator (fabric, rubber and metal expansion joints). The group is a wholly-owned subsidiary of the Swedish diversified investment company Investment AB Latour.

DENSIQ runs a sales-led, direct go-to-market model with dedicated sales and order teams, country-specific sales contacts, and 24/7 emergency service coverage. Revenue is generated through one-time product sales (seals, gaskets, mechanical seals, expansion joints, lubricants, composites) and professional services (maintenance, engineering, technical training, on-site interventions). The customer base spans process-industry verticals including oil and gas, chemicals, pulp and paper, power and energy, metals and mining, water treatment, manufacturing, food and beverage, pharma, and emerging battery manufacturing. ISO 9001 and ISO 14001 certifications are held across all operating entities.
