Goliath Heavy Duty Suction Excavator Hose: The UK's Go-To Vac-Ex Hose for Demanding Sites
Vacuum excavation has quietly become the standard method for safe, non-destructive digging across UK utilities, construction and rail projects. But the effectiveness of any vacuum excavator hinges on one component that rarely gets the credit it deserves: the suction hose. Choose the wrong one, and you're looking at split tubes, poor bend radius and costly downtime. Choose the right one and your vac-ex unit performs exactly as it should, shift after shift.
That's where the Goliath Heavy Duty Suction Excavator Hose comes in — a hose purpose-built for the toughest vacuum excavation applications on UK sites.
What Is the Goliath Suction Excavator Hose?
As the name suggests, Goliath is a giant of a hose. It's the result of years of refinement, engineered to strike a balance between flexibility, a good bend radius and — most importantly for fleet operators - genuine savings in use on the most demanding applications.
Goliath is typically fitted to vacuum excavators operating on a cassette system, where hose flexibility and kink resistance under constant reeling and unreeling really matter. If you're running vehicle-mounted vac-ex equipment on utility, highways or rail contracts, this is a hose designed specifically for that environment.
Built to Handle the Harshest Materials on Site
Suction excavation is used precisely because it avoids the damage risk that mechanical digging poses to buried services like gas, water, electric and telecoms infrastructure. But that safety benefit only holds up if the hose extracting the spoil can actually cope with what it's pulling through.
Goliath's thick natural rubber tube is built to withstand some of the most abrasive materials found on UK excavation sites, including:
- Dolomite
- Concrete pieces
- Asphalt
- Rocks
- Sand and gravel
Crucially, it's designed to withstand these materials for many hours of continuous use — not just cope with them briefly before wear sets in. For contractors running vac-ex units daily across multiple sites, that abrasion resistance translates directly into fewer hose replacements and less unplanned downtime.
Earthing and Safety as Standard
Static build-up is a genuine hazard when large volumes of dry, abrasive material are moving at speed through a hose — particularly on sites where flammable vapours or dust may be present. Goliath addresses this with an integral copper wire, allowing the hose to be properly earthed during use. It's a small detail, but on live sites it's the kind of specification that matters when a job is being assessed for compliance and risk.
Flexibility Where It Counts: Cassette Systems
Vehicle-mounted cassette systems put hoses through repeated tight bending cycles, and a hose that kinks or loses its shape under that stress quickly becomes a liability — reducing suction efficiency and increasing wear at the fold points.
Goliath is specifically engineered for perfect flexibility and kink resistance in these systems, maintaining consistent bore shape and suction performance even after sustained cassette use. That's a meaningful difference for operators who need reliable, repeatable performance rather than a hose that degrades after a handful of reels.
Available Sizes
Goliath is supplied with a 254mm bore, in coil lengths to suit different vac-ex setups:
| Bore Size | Coil Length |
|---|---|
| 254mm | 5.3m |
| 254mm | 6.9m |
| 254mm | 7.1m |
| 254mm | 7.9m |
This range of coil lengths means fleet operators can match hose length to specific machine configurations without compromising on the tube specification itself.
Why Choose Century Hose & Couplings for Your Vac-Ex Hose
Century Hose & Couplings Ltd is part of the wider R&G Fluid Power Group, operating from Preston with over £4 million of stock held to service demanding UK industries. That combination of deep stock holding and specialist product knowledge means suction excavation contractors, utility firms and plant hire companies can source heavy-duty hose like Goliath without the lead times that come with smaller suppliers.
Alongside suction excavator hose, Century Hose & Couplings supplies a full range of materials handling hose, couplings and fittings — useful if you're specifying an entire vac-ex hose assembly rather than just the tube itself.
Is Goliath Right for Your Fleet?
If your vacuum excavator is regularly handling abrasive spoil - dolomite, broken concrete, asphalt plannings, aggregate on a cassette-mounted system, Goliath is built with exactly that use case in mind. The combination of a thick abrasion-resistant tube, integral earthing wire and kink-resistant flexibility addresses the three most common failure points contractors report with lower-spec suction hose: premature wear, static risk and loss of bend performance.
