Why Vast Link

Built for Distributors and Contractors

What matters when you are putting our products into your market — and your reputation behind them.

Scale you can audit

70,000 m² and 420 people on site. Volume orders and repeat programmes are absorbed without extending your lead time.

You buy at the source

Production, inspection and packing are handled by our own team, not coordinated through layers of suppliers — which is why we can quote system-level pricing rather than SKU-by-SKU markups.

Complete range, one base

Pipes, press fittings and grooved fittings from the same production facility, shipped together, with matched tolerances across the system.

Your account is held to you

We supply on a named-account basis: once a market or customer is registered with us, that account is supplied through us and not reassigned.

Predictable delivery

15-day standard production lead time. Regular sizes are held in stock and dispatched within 3 days.

Full documentation

Mill Test Certificates to EN 10204 3.1 issued per heat, with complete material traceability from raw material to finished fitting.

How We Make It

Four Processes, Controlled In-House

Every stage of production runs inside our own facility — which is what allows us to answer technical questions directly, instead of relaying them.

  • Tube forming — coil slitting, roll forming, automatic TIG / plasma welding, online annealing and bright solution treatment.
  • Grooved fitting production — forging and casting, precision CNC machining and grooving to AWWA C606 and ISO 6182 dimensions.
  • Press fitting production — precision cold forming of thin-wall stainless fittings, automated O-ring seating, socket tolerance control.
  • Finishing & packing — pickling, passivation, polishing, marking, and container loading plans to reduce freight cost.
