Diploma is a UK-based group of specialised industrial distributors and suppliers serving niches such as seals, controls and life sciences consumables. Businesses add technical expertise and value-added logistics rather than competing purely on commodity price. Customers are typically OEMs, maintenance operations and laboratories that need reliable, application-specific products with short lead times.
