21 questions and answers covering size, use, technical checks and quotations.
What is a spiral suction hose used for?›
Vacuum can cause an unsuitable hose to collapse. A rigid PVC spiral supports the hose shape, but suitability depends on the series’ declared vacuum rating, bend radius, temperature and fluid. Verify those values for the intended suction duty.
How do yellow suction hose and heavy green spiral hose differ?›
Do not compare two products by colour or appearance alone. Compare material grade, actual diameter, wall thickness or weight per metre, working pressure, application and current product markings in the same table.
How should hose diameter be selected to help prevent pump cavitation in suction systems?›
If Heavy-Duty Red Discharge Hose is to be used on pump suction, check the actual internal diameter, vacuum resistance, minimum bend radius and fluid temperature together. A tight bend or small air leak can restrict the passage and significantly reduce pump suction performance. Use the pipe and hose diameter calculator. Open the calculator
What do spiral hose colours—yellow, green, red and clear—indicate?›
Spiral hose series can serve different suction and discharge duties, but colour alone does not establish a vacuum or pressure rating. Choose the series by its published vacuum, positive-pressure and fluid compatibility data. A transparent wall allows visual inspection when the hose is suitable for that fluid.
What should I check when buying a vacuum-truck hose, and how can I extend its service life?›
Select fittings to suit the actual internal or external diameter and operating pressure of Heavy-Duty Red Discharge Hose. Cuts must be square and free of burrs; clamps must not cut into the body, and a controlled leak-tightness test must be completed before commissioning the line.
Can spiral suction hoses withstand freezing and cold weather?›
Confirm the UV and temperature resistance of Heavy-Duty Red Discharge Hose using current technical product information. Store it in the shade on a clean surface when not in use; reducing exposure to sharp surfaces, crushing and extreme temperatures helps protect its service life.
How does clear steel-wire-reinforced hose differ from standard PVC spiral hose?›
Do not compare two products by colour or appearance alone. Compare material grade, actual diameter, wall thickness or weight per metre, working pressure, application and current product markings in the same table. When considering “How does clear steel-wire-reinforced hose differ from standard PVC spiral hose?”, compare the product markings with actual site conditions; do not select a size or class by assumption.
Which spiral hose should be selected for extracting dust, wood chips or granules?›
Select a dust-extraction hose by its declared abrasion resistance, vacuum rating, bend radius and suitability for the conveyed material. A spiral structure alone does not guarantee that a hose will never collapse or clog; verify the series’ technical data for the installation.
How should a spiral hose be selected for whirlpool and spa systems?›
For pool and spa hose connections, match the actual hose outside diameter and fitting standard; a nominal size such as 20, 32 or 50 mm alone does not prove compatibility. Use only the joining method and adhesive approved for the selected products, and confirm chemical, temperature and pressure limits. Test joints according to the installation instructions.
What requirements must clear spiral hoses meet for food transfer?›
Food, milk or drinking-water use requires current documentation for the specific hose and the intended fluid and contact conditions. A clear or smooth wall alone does not establish food-contact suitability or a phthalate-free formulation. Request the relevant product declaration before ordering.
How are wholesale spiral hose prices determined, and are coil lengths standard?›
The roll or coil length of Heavy-Duty Red Discharge Hose may vary with the size and current production option. State your preference for a single continuous roll alongside the total length in the quotation request; confirm stock and package length before dispatch. Check the current price list. Current price list
What affects the price of a vacuum-truck hose and the metre price of spiral hose?›
The listed starting price is 39.96 TRY. State the total length, number of coils and delivery city in your quotation request. Compare products of the same size and series; price alone does not make different classes equivalent.
Can Heavy-Duty Red Discharge Hose be used as a water discharge hose?›
When selecting Heavy-Duty Red Discharge Hose, consider the actual size, application, line or installation length, operating conditions and connection method together. Confirm current product information, stock and packaging details before ordering.
Can Heavy-Duty Red Discharge Hose be used for suction?›
If Heavy-Duty Red Discharge Hose is to be used on pump suction, check the actual internal diameter, vacuum resistance, minimum bend radius and fluid temperature together. A tight bend or small air leak can restrict the passage and significantly reduce pump suction performance. When considering “Can Heavy-Duty Red Discharge Hose be used for suction?”, compare the product label with actual site conditions; do not choose a size or class on assumptions.
Can Heavy-Duty Red Discharge Hose be used for water discharge from a vacuum truck?›
For Heavy-Duty Red Discharge Hose, consider the actual size, application, line or installation length, operating conditions and connection method together. Confirm current product information, stock and packaging before ordering. When considering “Can Heavy-Duty Red Discharge Hose be used for water discharge from a vacuum truck?”, compare the product markings with actual site conditions; do not select a size or class by assumption.
Does Heavy-Duty Red Discharge Hose have a ribbed outer surface?›
For Heavy-Duty Red Discharge Hose, consider the actual size, application, line or installation length, operating conditions and connection method together. Confirm current product information, stock and packaging before ordering. When considering “Does Heavy-Duty Red Discharge Hose have a ribbed outer surface?”, compare the product markings with actual site conditions; do not select a size or class by assumption.
How does Heavy-Duty Red Discharge Hose differ from yellow suction hose?›
Do not compare two products by colour or appearance alone. Compare material grade, actual diameter, wall thickness or weight per metre, working pressure, application and current product markings in the same table. When considering “How does Heavy-Duty Red Discharge Hose differ from yellow suction hose?”, compare the product markings with actual site conditions; do not select a size or class by assumption.
Can Heavy-Duty Red Discharge Hose be used to unload a tanker?›

What coil lengths can I order for Heavy-Duty Red Discharge Hose?›
State the total metres and continuous line length separately for Heavy-Duty Red Discharge Hose. Roll length and cutting options are confirmed in the accepted quotation; diameter does not determine roll length. Review the sizes in the same product family. Related sizes and products
Does Heavy-Duty Red Discharge Hose serve the same purpose in suction and discharge lines?›
Suction requires verified vacuum data, while discharge requires positive-pressure data. Do not substitute one hose for the other based on appearance. Check both the pump requirements and the selected hose ratings.
What information is needed for a metre-price quote for Heavy-Duty Red Discharge Hose?›
For Heavy-Duty Red Discharge Hose, state the total metres, required continuous length and conveyed fluid. Standard and heavy-duty series and their connections can have different prices; compare equivalent specifications.
