Sleeve It

What Sleeve It does

Sleeve It Limited is a UK-based specialty manufacturer established in 2003 and headquartered in Bamber Bridge, Preston, Lancashire. The company designs and produces protective sleeving, thermal protection products, electrical insulation materials, silicone products, tying cord, pipe identification markers, antibacterial cords, and gas supply accessories under sub-brands including Firesleeve, Symel, Vidaflex, Novaflex, and Cordgienic. Core technology centres on E-glass fibre yarns, basalt fibre, and silicone elastomer coatings engineered for fire resistance (continuous operation up to 260°C, molten splash resistance up to 1200°C) and thermal endurance up to 750°C. The company holds an unusually broad certification portfolio including EN45545-2 (rail), AS1072/AS1055E (aerospace), MSHA (mining), UL94 V0, EC 60695-11-10, ISO 11925-2, BS1710 (pipe identification), ISO 22196 (antibacterial), and IEC Class H (electrical insulation), which gates entry into regulated end-markets.

Sleeve It operates as a privately-held independent manufacturer with 1-10 employees and no disclosed external funding, parent company, or M&A activity. The company manufactures Firesleeve domestically in Britain in sizes from 6mm to 203mm and offers custom cutting services. Revenue is generated entirely through direct hardware sales: an e-commerce storefront at sleeveit.co.uk with same-day shipping for in-stock items and UK next-day delivery, supplemented by quote-based phone and email sales, plus a US distribution partnership with National Firesleeve established in March 2023. Customers are distributed across aerospace, automotive, rail, marine, military, mining, energy/offshore, and healthcare verticals with no disclosed named anchor accounts.

The business model is purely transactional hardware sales with no recurring software, subscription, or service revenue component. Pricing is not publicly disclosed and follows a quote-based model. Marketing relies on technical blog content, trade show participation (including Fluid Power & Systems), email newsletter, and organic social media rather than paid acquisition. Geographic reach spans the UK, continental Europe, the United States, and Southeast Asia (including Vietnam).
