Polyhose Multipurpose Hose Pipe
This hose is intended for medium-pressure fluid transfer.
Typical applications include:
- Agricultural pesticide spraying
- Fungicide spraying
- Fertilizer solution transfer
- High pressure watering
- Garden irrigation
- Horticulture
- Air supply
- Water transfer
- Industrial cleaning
- General-purpose compressed air (within rating)
Not recommended for:
- Petroleum fuels
- Steam
- Hot oil
- Food-grade fluids
- Hydraulic oil
- High-temperature chemicals
Although PH368 is a proprietary Polyhose product, the following standards are commonly referenced for similar multipurpose PVC hoses:

- ISO 1307 Hose dimensions and tolerances
- ISO 1402 Hydrostatic pressure testing
- ISO 8033 Flexibility testing
- ISO 4671 Measurement of hose dimensions
- ISO 7233 Vacuum resistance (where applicable)
- ISO 5774 Textile reinforced thermoplastic hose guidance
- IS 9573 Rubber and thermoplastic hoses (general)
- ASTM D2240 Hardness testing
- ASTM D412 Tensile properties
- RoHS Restriction of hazardous substances (where specified)
- REACH Chemical compliance (where specified
Construction
Maintenance requirements and best practices
Material Specifications
Layers
- Inner Tube - Plasticized Black PVC
- Reinforcement - High tensile synthetic fibre braid
- Outer Cover - Abrasion resistant thermoplastic PVC compound
- Visual inspection before each use for cuts, abrasions, kinks, flattening, or damaged braid; replace if cover or reinforcement is exposed.
- Avoid sharp bends; respect minimum bend radius as per datasheet to prevent kinking and braid damage.
- Store coiled in cool, shaded, dry place away from direct sunlight and ozone sources (UV degrades PVC over time).
- Periodic pressure test (hydrostatic test) per manufacturer recommendation after installation and after repairs. Manufacturer should provide maximum test pressure and recommended test intervals.
- Clean after use if used with corrosive chemicals; flush with compatible fluid and dry. Keep records of service life for safety‑critical uses
- Inner tube: Plasticized PVC — formulation for fluid compatibility (manufacturer provides specific compound details on request).
- Reinforcement: Single braid synthetic fibre (likely polyester or nylon braided yarn).
- Outer cover: Abrasion‑resistant thermo‑compound (PVC/TPV type).
- Compatibility: Suitable for water, many pesticides and general chemicals — check chemical compatibility sheet for specific chemicals (manufacturer will confirm compatibility with particular pesticides/fertilizers)
