Factory 12mm Food Grade Milk Hose

Basic Characteristics of PVC Clear Hose

PVC clear hose is a lightweight, flexible plastic tubing made from polyvinyl chloride (PVC) material, known for its high transparency, which allows for easy visual inspection of fluid flow. Its smooth inner wall minimizes fluid resistance, making it suitable for low-pressure applications at typical temperatures (usually between -10°C and +60°C). Standard sizes range from 6mm to 50mm in inner diameter, with a typical working pressure of no more than 0.3MPa.

Compared to rubber hoses, PVC hoses are more cost-effective but slightly less flexible. Unlike PE hoses, they have weaker UV resistance and require shading for prolonged outdoor use. Common colors include fully transparent or light blue transparent, with some models featuring colored stripes for identification.The common colors are fully transparent or light blue transparent, and some models have colored stripes to distinguish their uses.

Key Advantages:

• Instant Visibility: Allows real-time monitoring of fluid clarity and flow without interrupting operations

• Lightweight: Over 70% lighter than metal pipes of the same size, enabling easier installation

• Economical: Priced at about 1/5 to 1/3 of food-grade silicone hoses

Primary Applications (Bullet Points)

2.1 Household & Commercial Uses

• Gardening/Irrigation: Connects to sprayers or drip systems; transparency helps detect clogs

• Aquarium Maintenance: Used for water changes, allowing users to monitor water clarity and avoid disturbing substrate

• Small Fountains: Transparent tubing simplifies maintenance checks in recirculating systems

• Water Dispensers: NSF-certified models are safe for drinking water transport

2.2 Industrial & Light-Duty Uses

• Pneumatic Tools: Delivers compressed air while enabling detection of moisture buildup (requires pressure-rated models)

• Packaging Machinery: Clear tubing aids in visual monitoring of material flow with sensors

• Laboratory Use: Temporarily transfers distilled or deionized water

Target audience for PVC Clear Hose

Categories of Users for PVC Clear Hose

1. Household & Individual Users

• Gardening Enthusiasts

• Used for watering potted plants, vegetable gardens, or connecting to drip irrigation systems. The transparent tube allows real-time monitoring of water flow to prevent clogs.

• Ideal for scenarios requiring frequent hose movement (e.g., balcony gardening).

• Pet/Aquarium Owners

• Safe for aquarium water changes and cleaning, preventing substrate disturbance or fish stress.

• Suitable for reptile terrarium misting systems (requires regular cleaning).

• DIY Hobbyists

• Used in small homemade fountains or water circulation projects.

• Temporary drainage solutions (e.g., car washing, patio water removal).

2. Commercial & Light Industrial Users

• Small Food & Beverage Businesses

• Connects water dispensers or coffee machines (requires food-grade certified models).

• Temporary transfer of non-greasy liquids (e.g., syrups, diluted juices).

• Cleaning Service Providers

• Low-pressure washing equipment tubing; transparency helps detect detergent residue.

• Drainage hose for portable water suction machines (short-term use).

• 
  

3. Industry-Specific Users

• Greenhouse Farmers

• Acts as a secondary pipe in low-pressure micro-irrigation systems; transparency helps locate leaks.

• Note: Prolonged UV exposure may cause degradation—seasonal replacement recommended.

• Event Planners

• Temporary water feature setups or decorative fountain circulation systems.

• For outdoor use, choose UV-resistant models or add protective sleeves.

Not Recommended for These Users & Scenarios

• High-Temperature/High-Pressure Needs: E.g., steam equipment or boiler maintenance personnel.

• Chemical Industry Users: Scenarios involving organic solvents, strong acids, or alkalis.

• Long-Term Outdoor Fixed Installations: E.g., solar water heater piping (UV exposure causes brittleness).

Selection Tips

• Household Users: Opt for standard 6-12mm inner diameter hoses—affordable and easy to replace.

• Commercial Users: Choose reinforced helical models (kink-resistant) and verify food-grade certifications if needed.

• Industrial Users: For durability, pair with quick-connect fittings to minimize wear from frequent disassembly.

Comparison of PVC Clear Hose Types

4.1 Key Selection Criteria

• Inner Diameter: Match to flow requirements, e.g.,

• 6mm for small pumps (<5L/min)

• 12mm for general gardening (15–20L/min)

• Pressure Rating: Choose reinforced types for gases, standard for liquids

• Fitting Compatibility: Barbed fittings suit hoses with 1.5–2mm wall thickness

4.2 Quality Checks

1. Odor Test: High-quality hoses have no strong plastic smell

2. Flexibility Test: Should rebound quickly after bending

3. Labeling: Legitimate products display size, standards, and certifications

Installation & Maintenance

Installation:

• Avoid sharp bends (minimum bending radius ≥ 2 times the hose diameter).

• Use soft cable ties for fastening to prevent crushing.

Long-term Usage Notes:

• Regular Inspection: Replace immediately if discoloration (yellowing), hardening, or cracks are observed.

• Cleaning Method:

• Rinse with warm water.

• Soak in mild detergent for stubborn stains.

• Storage Requirements:

• Coil neatly when storing.

• Keep away from high temperatures and sharp objects.

Safety Limitations

Avoid These Scenarios:

• Temperatures >65°C (hot water/steam)

• Prolonged UV exposure (unless shaded)

• Transporting oils/greases (may leach plasticizers)

• Pulsing pressures exceeding 150% of rated capacity
