TPR (Rubber Pvc Mixed) Multipurpose Hose 300psi

Product Overview

The TPR (Rubber PVC Mixed) Multipurpose Hose 300psi is a high-performance, non-marking synthetic rubber hose engineered for air, oil, and medium-grade fuel transfer. As a leading manufacturer in china, our product exceeds the standard EN 854 type RTPR requirements, providing a reliable solution for construction, shipyard, mining, and agricultural sectors. This TPR multipurpose hose combines the flexibility of rubber with the oil resistance of PVC, offering a unique material definition that balances durability and cost.

Structurally, this rubber hose features a smooth, oil-resistant tube and cover made from TPR (NBR/PVC blend) with 1ply or 2ply polyester thread braiding reinforcement. The specification ensures working pressure up to 20bar (300psi) with a 3:1 safety factor (burst pressure 60bar/900psi), operating reliably from -30°C (-22°F) to +80°C (+176°F). Key advantages include a non-marking cover, exceptional resistance to ozone, weather, and ultraviolet (UV) light, making it ideal for outdoor and sensitive surface applications.

Common applications include pneumatic systems, return lines for low-pressure hydraulics, lubrication lines, and fuel transfer where medium-grade resistance is sufficient. This TPR multipurpose hose solves critical user pain points: cover marking on finished surfaces, premature cracking from sun exposure, and limited oil resistance in standard PVC hoses. We provide full traceability and quality certification, ensuring every hose assembly meets stringent factory tests.

Product Advantages

• 300psi Reliable Performance: Consistent working pressure for air, oil, and fuel applications.
• Non-Marking Cover: Eliminates surface damage on floors, equipment, and finished goods.
• Ozone, Weather & UV Resistant: Excellent outdoor lifespan without cracking or hardening.
• Smooth Oil-Resistant Tube: Compatible with mineral oils, diesel, and medium-grade fuels.
• Flexible & Kink-Resistant: Easy routing in tight spaces; reduces Assembly time.
• Cost-Effective TPR Blend: More affordable than pure rubber, with superior oil resistance to PVC.

Applicable Users: Construction contractors, shipyard maintenance teams, mining equipment operators, agricultural cooperatives, and facility maintenance departments seeking a durable, wholesale or bulksupply of general-purpose hoses.

Structure and Materials

• Tube: Smooth TPR (NBR/PVC blend), black, oil and fuel-resistant. Ensures low flow resistance and media purity.
• Reinforcement: 1 or 2 plies of high-tensile polyester thread braiding. Provides strength without rigidity.
• Cover: Smooth TPR (NBR/PVC blend), non-marking, ozone, weather, and UV resistant. Suitable for outdoor use.

Why Polyester Braiding Instead of Wire?

Unlike Wire Braided Hose or Wire Spiral Hose designed for High Pressure Hose applications (e.g., 4000psi+), the TPR multipurpose hose uses polyester braiding. Polyester offers excellent strength for medium-pressure work (300psi), superior flexibility at low temperatures, and does not corrode when the cover is damaged. This is the optimal solution for air, oil, and fuel return lines where a heavy wire reinforcement would add unnecessary cost and stiffness.

Application Industries

• Construction: Pneumatic tools, concrete pumps, compressor lines.
• Shipyards: Deck wash-down, low-pressure oil transfer, air lines.
• Mining: Dust suppression systems, lubrication lines, water spray bars.
• Agriculture: Sprayers, tractor remote lines, fuel transfer from tanks.
• Industrial Manufacturing: Assembly line pneumatics, machine tool coolant lines.
• Facility Maintenance: Shop air, overhead lubricators, drain lines.

Precise Selection Professional Guide

It’s More Than a Hose: The Complete Hose Assembly

A hose assembly is the complete, ready-to-install product. For maximum safety and service life, we recommend factory-crimped assemblies. We supply the following fittings and accessories:

• Crimped fittings: Permanent, leak-free connection for high reliability.
• Reusable fittings: For field repair without special tools.
• Adapters: Convert between NPT, BSP, JIC, and ORFS threads.
• Flanges: For larger diameter connections (above 1 inch).
• Protective sleeves & guards: Abrasion resistance at hose contact points.

Selecting the right crimped fittings or reusable fittings depends on your application pressure and environment. For OEM ODM customers, we can pre-assemble hoses with custom adapters and flanges to reduce your installation labor.

TPR Multipurpose Hose vs. World Standards

Solving Common Field Problems

Problem: Air hoses leaving black marks on white warehouse floors or finished marine decks.
Solution: Our non-marking TPR cover eliminates this issue entirely.

Problem: Hose hardening and cracking after 6 months of outdoor use.
Solution: UV and ozone-resistant compound extends service life by 3x compared to standard PVC.

Problem: Diesel fuel causing PVC hoses to swell and leak.
Solution: TPR blend resists medium-grade fuels including diesel and biodiesel blends.

Installation, Operation, and Maintenance Guide

1. Inspection: Before Assembly, check for any cuts, abrasions, or bulges.
2. Minimum Bend Radius: Do not bend below 3x the hose OD to avoid kinking.
3. Fitting Selection: Always use crimped fittings or reusable fittings matched to the hose OD.
4. Routing: Avoid sharp edges. Use protective sleeves or guards where abrasion is likely.
5. Fluid Compatibility: Confirm your fluid is compatible with TPR (NBR/PVC blend). Not for brake fluids or strong acids.
6. Storage: Keep away from ozone sources (electric motors, welding equipment) and direct sunlight when not in use.

Frequently Asked Questions (FAQ)

Q1: What is the exact definition of a TPR multipurpose hose?
A: TPR stands for Thermoplastic Rubber, a blend of PVC and NBR rubber. It combines the oil resistance of rubber with the flexibility and cost-effectiveness of PVC.

Q2: Can I use this rubber hose for gasoline?
A: Yes, for medium-grade fuels including gasoline and diesel. For continuous immersion or high-pressure fuel injection systems, use a dedicated fuel High Pressure Hose.

Q3: Do you supply pre-assembled hoses?
A: Yes. We provide complete hose assembly with crimped fittings, adapters, or flanges as per your specification.

Q4: What is your standard length?
A: Standard lengths are 50m or 100m per roll. Custom lengths and bulk cut pieces are available.

Q5: Are protective sleeves necessary?
A: Not always, but recommended for high-traffic areas or where the hose contacts sharp metal edges. We offer both guards and sleeves.

Q6: What is your MOQ for wholesale orders?
A: No fixed MOQ. We welcome bulk, wholesale, and even small-quantity distributor trial orders.
