Clear PVC Spiral Reinforced Hose – Steel Wire Suction Hose

Clear PVC Spiral Reinforced Hose – Steel Wire Suction Hose

FOSITE clear PVC spiral reinforced hose is a flexible, transparent suction and discharge hose built around a high-carbon steel wire helix, made for distributors, industrial buyers, farms and OEM brands that need dependable fluid transfer in demanding conditions. The crystal-clear PVC wall lets operators see the flow at a glance, while the embedded spiral wire stops the hose from collapsing under vacuum and keeps it from kinking when it is dragged across a jobsite. Available from 1/4 inch to 8 inch inner diameter in phthalate-free, food-grade and antistatic compounds, it handles water, mild chemicals, slurry, light solids and food-grade transfer — supplied in coils, cut lengths or fully assembled with couplings. Every PVC spiral reinforced hose order is produced to your bore, wall thickness and pressure class.

Key Features

1. Steel wire helix reinforcement

High-carbon galvanized wire is wound continuously into the wall, so the hose resists vacuum collapse and keeps its full bore on tight bends instead of flattening like an unreinforced tube.

2. Crystal-clear transparent wall

The see-through PVC shows blockages, air bubbles and product colour instantly — operators spot a starved pump or a slug of air before it becomes downtime.

3. Wide size and pressure range

PVC spiral reinforced hose sizes run from 6 mm to 200 mm (1/4" to 8") inner diameter, wall 2.0–8.0 mm, working pressure 0.3–0.8 MPa by size, burst pressure at least 3× the working rating.

4. Chemical and abrasion resistance

The smooth bore resists mild acids, alkalis, salt water, detergents and suspended solids, which makes this PVC spiral reinforced hose suitable for slurry and light-solids transfer as well as clean water.

5. Temperature and weather tolerance

Stable from -10°C to +65°C in continuous service; a UV-stabilised compound is available for outdoor irrigation and long-term sun exposure.

Materials & Finish

Assembly & Installation

Tools needed: hose cutter or sharp knife, barbed insert fittings, hose clamps (2 per joint), hot water (60–70°C) for softening, pressure gauge.

1. Measure the run and cut the hose square with a hose cutter — a clean, burr-free cut is what keeps the joint leak-free.
2. Wrap the cut end with tape before cutting if the wire ends may protrude, then remove the tape.
3. Soften the end in hot water for 30–60 seconds to make the PVC pliable.
4. Push the barbed fitting fully home, past the last barb, in one steady motion.
5. Fit two clamps behind the barb and tighten evenly, 180° apart.
6. Pressure-test at 1.5× working pressure for 5 minutes before putting the line into service.

Usage notes: keep the bend radius at 6× outside diameter or more — a tighter bend stresses the wire and shortens service life. Cut the PVC spiral reinforced hose with a hose cutter, never a saw: a frayed wire end will pierce the wall. Do not drag it over sharp edges or hot surfaces, and do not use it for aromatic solvents, concentrated acids or ketones. Store coiled, flat, out of direct sunlight, away from heat sources and ozone-generating equipment. For vacuum duty, keep the coil ends straight for at least 3× the diameter to avoid stressing the helix.

Applications

The PVC spiral reinforced hose is specified wherever a clear line has to bend around equipment, survive vacuum and still let the operator see what is moving through it.

• Agricultural irrigation & spraying — drip and sprinkler feed lines, pesticide and fertiliser transfer, greenhouse watering; the clear wall lets growers confirm flow at each outlet.
• Pump suction & site dewatering — construction dewatering, sump and trash pump suction, flood recovery; this is the classic PVC spiral reinforced hose duty, where the wire helix holds shape under negative pressure.
• Industrial fluid transfer — machine coolant, hydraulic fluid return lines, chemical dosing and tank filling in workshops and small plants.
• Food & beverage handling — milk, juice, syrup, edible oil and CIP cleaning lines with the food-grade compound; smooth bore supports flushing between batches.
• Aquaculture & fish ponds — pond drainage, aeration supply, water exchange and fish-transfer lines in fresh and salt water.
• Mining, slurry & light solids — tailings lines, sand and gravel wash-down, powder and granule conveying where abrasion resistance matters.
• Pool, spa & cleaning — pool vacuum heads, spa drain-down and general washdown duty; light enough to handle by one operator.

FAQ

Q: What is a PVC spiral reinforced hose?
A: It is a flexible PVC hose with a high-carbon steel wire wound in a spiral inside the wall. The wire carries the load, so the hose can be pulled, bent and used under vacuum without collapsing — something a plain PVC tube cannot do.

Q: What sizes and pressures can you supply?
A: Our PVC spiral reinforced hose runs from 6 mm to 200 mm (1/4" to 8"), wall 2.0–8.0 mm, working pressure 0.3–0.8 MPa depending on bore, with a burst rating of at least three times the working pressure. Tell us the medium and flow rate and we will confirm the size.

Q: Can this hose be used for suction duty?
A: Yes. The steel helix is bonded into the wall, so a PVC spiral reinforced hose keeps its bore open under negative pressure, up to full vacuum on sizes 50 mm and below. For larger sizes we recommend a heavier wall, and the coil ends should be kept straight for at least three diameters.

Q: Is the hose food-grade?
A: The standard compound is phthalate-free but not food-contact certified. We supply a food-grade version tested to FDA 21 CFR 177.2600 and EU 10/2011 on request, with the migration report attached to the shipment.

Q: What is the MOQ and lead time?
A: Standard MOQ is 500 m per size, and production takes 15–25 working days after deposit. Trial orders below MOQ can be discussed for stock colours.

Q: How is the hose packed and loaded?
A: Coils of 30, 50 or 100 m are wrapped in PE film and woven bag, then cartoned or palletised. Loading quantity depends on bore and packing — send us your order list and we will confirm a container plan.

Q: Can you print our logo on the hose?
A: Yes. Brand, size, working pressure and certification marks can be printed on the wall, and the stripe colour can match your brand. Private label starts from 500 m per size.
