What Hallite Seals does

Hallite Seals (legal name Hallite Seals International Limited) is a specialist manufacturer of hydraulic and pneumatic seals serving OEMs in off-highway equipment, construction, mining, agriculture, general industrial, and aerospace applications. Founded in the early 1900s as Hall & Hall and headquartered in Hampton, United Kingdom, the company offers more than 105,000 stocked products plus bespoke custom seals, organized around core categories of hydraulic seals (rod, piston, V-pack, buffer), pneumatic seals, bearings and wear rings, and branded material systems including Armorlene® PTFE, Hythane®, and the OptiSeal® spring-energized sealing system. Its competitive positioning rests on proprietary polymer formulations, a 720-series unitized piston with over-molded non-metal bearing material on steel bodies, and a full lifecycle capability from compound development through in-house testing.

The company operates as a wholly-owned subsidiary of Compagnie Générale des Établissements Michelin (Michelin Group), with directly operated offices in the UK, USA, Germany, Italy, Canada, India, China, and Australia, plus distribution into Brazil. It maintains a 251–500 employee base, ISO 9001/14001/45001 certifications, and a zero-waste-to-landfill Australian facility. Hallite reaches OEM accounts through a combination of an approved global distributor network for local supply and direct enterprise field sales supported by industry exhibitions (EXCON 2025, CONEXPO 2026), a multi-language digital platform with a Product Finder and 3D CAD download service, and educational content including webinars and the Fluid Power 101 App developed in partnership with Milwaukee School of Engineering.

Hallite generates revenue through one-time sales of sealing components to OEMs and through approved distributors, with quote-based industrial pricing and no disclosed public price list. Its growth has been augmented by two acquisitions in roughly 24 months: SealTeam Australia in March 2023 and a pending acquisition of Italy-based Aston Seals signed in July 2025. The company is private, does not disclose revenue, and competes on material science depth, catalog breadth, and global local-support rather than on software or AI-driven differentiation.
