Why the wall is corrugated
A suction hose has one structural problem: when the pump pulls, atmospheric pressure tries to flatten the tube shut. The family's published construction is the wall build itself: a smooth flexible PVC inner wall inside a corrugated PVC outer wall. The company describes the corrugated outer wall as resisting abrasion, weathering and scraping, and as bending easily. The standard colour is green, with the outer ribs shown in white, blue or black variants, and transparent or semi-transparent walls are listed for the family.
The family's published specification
| Item | Published data (suction family) |
|---|---|
| Inside diameter | 3/4 in to 8 in (suction family range; the rating at your bore is confirmed in the quotation) |
| Working pressure | 3 to 8 bar (suction family range across its bores; the rating at your bore is confirmed in the quotation) |
| Burst pressure | 9 to 24 bar (suction family range across its bores; the rating at your bore is confirmed in the quotation) |
| Temperature range | -5 °C to +65 °C (suction family range; the figure for your bore and build is confirmed in the quotation) |
| Roll length | 10 m to 30 m (suction family range; the lengths offered for your bore are confirmed in the quotation) |
| Standard colour | Green; transparent and semi-transparent options listed |
| Minimum order | 100 m (suction family figure, product page and FAQ agree; the minimum for your bore and build is confirmed in the quotation) |
Family figures, as labelled: bore, pressures and lengths span the family's sizes, and the rating at your bore is confirmed in the quotation. The family's own page — PVC suction hose — carries the ordering context, including its published roll lengths: 10 m to 30 m for this family (suction family range; the lengths offered for your bore are confirmed in the quotation), shorter than layflat coils. The variants named for the family — anti-static, temperature-resistant and food-grade builds — are variants of this same corrugated construction, specified at their own names in an enquiry.
Corrugated wall or steel wire — the two vacuum builds
Two published constructions serve vacuum duty in this range, and they are built differently. The corrugated suction hose is a smooth flexible PVC inner wall inside a corrugated PVC outer wall — the suction family's own construction. The PVC steel wire hose embeds a spiral steel skeleton in a transparent wall — the clear build, listed for suction and delivery together, with a published small bending radius. Which construction a run takes is settled against the duty in the enquiry: the medium, whether sight of the flow matters, the bend the route imposes and whether the same hose must also deliver. If the corrugated build is your candidate, its family data is the table above, not a figure borrowed from the wire build.
Is corrugated suction hose the same product as the PVC suction hose on this site?
Yes — the corrugated outer wall is the suction family's published construction, so the family page describes the product as a whole and the wall build is the same construction.
Can the corrugated wall handle tight bends?
The family's published description records the corrugated outer wall as bending easily, but no minimum bend radius for this family is published in the company's data. State the tightest bend your route imposes in the enquiry and have it answered for your bore in the quotation.
Does it come in clear?
Transparent and semi-transparent walls are listed for the family. State that you want a transparent wall, at your bore, in the enquiry; the clear PVC hose guide compares the range's transparent constructions.
Request a Quotation
Send the hose family, bore size, working pressure, length per roll and total quantity. MOQ, packing and lead time are confirmed in the written quotation for your exact specification. If the hose will be supplied as a finished assembly, name the coupling standard you need (for example camlock type and size, flange or thread) — or state that you need bare hose only.
