What Tykoflex does

Tykoflex AB is a Swedish niche hardware manufacturer specializing in fiber optic joint closures, cable splicing systems, and stainless steel modular enclosures for demanding environments, founded in 1958 and headquartered in Tyresö, just outside Stockholm. The company's core platform is the T240 modular closure system — acidproof stainless steel lockable enclosures rated for both overpressure and vacuum — with over 500,000 units installed in Swedish fiber networks. The portfolio is extended by Seaflex® submarine cable joints (tested to 200 kN tensile loads), Beachflex™ offshore closures, the cold compression cable sealing method for micro cables (Ø 1.8-12.0 mm), the new Tykoflex 19" rack system launched in October 2024, and the RL30 obstruction light co-developed with Telia under ICAO standards. A separate industrial product line, the M42 quick coupling system, serves pipe and hose applications across sizes from 1.5" to 8" in galvanized, aluminum, and stainless steel variants.

The company serves nine distinct use-case segments: telecom operators (backbone, FTTH, data centers), submarine/marine infrastructure, wind power, power grid utilities (OPGW/ADSS), mining, railway, oil and gas, motorway infrastructure, and agriculture/irrigation. Go-to-market is direct field sales with named representatives for Swedish telecom (Andreas Lydell, Christian Tiilikainen, Ove Gabrielsson), quick couplings (Ronnie Berglund), and international accounts (Jari Tuomela), supported by inside sales (Helga Gustafsson). Revenue mechanics are quote-based B2B hardware sales with multi-year contracts, supplemented by OPGW certification training services for Svenska kraftnät. Channels include the company website (product catalogs, technical documentation, instruction videos), trade shows (Submarine Networks World, DSEI 2025, Eurosatory, ANGA COM, Elfack), and earned media in industry publications.

Since January 2023, Tykoflex has operated as a subsidiary of Lagercrantz Group, a Nasdaq Stockholm-listed diversified industrial conglomerate. The company is ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified, complies with REACH SVHC and RoHS, and in December 2025 joined an EU-funded partnership with Baltic Offshore and Lilaco Offshore to strengthen Baltic Sea submarine cable repair preparedness. The company is led by CEO and Sales/Marketing Manager Richard Petersson Wigh.
