About South Coast Seals
The UK's mechanical seal specialists
Supplying mechanical seal kits to pump engineers across the UK for nearly 50 years. Deep technical expertise, large stockholding, fast delivery.
Rooted in family. Built on knowledge, relationships and a passion for getting it right
A family business, in every sense.
South Coast Seals has been family-run for nearly 50 years, with roots in this industry going back to 1980. We started in Fareham, settled in Waterlooville, and have spent the years in between building something we're genuinely proud of — a small team that cares about the job, knows our customers by name, and treats every order like it matters. Because it does.
When your name's on the door, things are different. You pick up the phone yourself. You stay late to get a kit out because someone, somewhere, is waiting on it. You remember the customers who've stuck with you for years — and they remember why.
Pump repair companies, maintenance engineers, service technicians across the UK — they call us because they know they'll get a real person who knows their stuff, and a business that takes their problem as seriously as they do.
With decades of hands-on experience between us, there's very little we haven't seen. A pump model number, a seal reference, even a photograph of a failed component — we'll find the right part and get it to you without delay. That's the promise. It always has been.
