Key Features of Sandhyaflex IS 446 Rubber Hose

Standard Conformance:
Made to meet IS:446 (Indian Standard) for rubber industrial hoses typically air hose types (Type 1, Type 2 and Type 3). (sandhyaenterprises.co.in)

Construction:

• Inner lining: Smooth rubber compound with good oxidation resistance.

• Reinforcement: Braided textile (yarn) for strength and flexibility.

• Outer cover: Abrasion, weather and oil-resistant rubber. (sandhyaenterprises.co.in)

Pressure Ratings by Type:

• Type 1: Working Pressure 0.7 MPa & Burst 2.8 MPa

• Type 2: Working Pressure 1.0 MPa & Burst 4.0 MPa

• Type 3: Working Pressure 1.4 MPa & Burst 5.6 MPa
  (Higher Type numbers = stronger, heavier-duty construction.) (sandhyaenterprises.co.in)

Sizes:
Typically available from 12 mm to 50 mm inner diameter in coils (e.g., 100 m rolls). (ExportersIndia)

Temperature Range:
Roughly -10 C to 120 C depending on exact compound and reinforcement. (sandhyaenterprises.co.in)

What IS 446 Means

IS:446/1987 is an Indian Bureau of Standards specification covering rubber hoses with textile braid reinforcement used for air and industrial service. Hoses made to this standard are generally used for compressed air and light water/industrial fluids, not high-pressure hydraulic fluids. (sandhyaenterprises.co.in)

Notes

• The term Sandhyaflex 446 Rubber Hose usually refers to this IS 446-compliant series offered by Sandhyaflex, rather than a unique model number. (ExportersIndia)

• If you need the hose for heavy slurry or mining liquids, those are typically different Sandhyaflex hose types (e.g., slurry/mud or suction/discharge hoses) with different specifications. (Sandhya Enterprises)

Wear Resistance for Longevity

Engineered with a special rubber compound and a thickness of 5 millimeters, this hose demonstrates exceptional wear resistance. Its robust material and wrap finish minimize abrasion, making it capable of withstanding frequent or heavy-duty air and water flow. This durability not only reduces the need for frequent replacements but also lowers long-term maintenance costs for industrial or commercial users.


Flexible Applications and Easy Handling

The IS 446 Rubber Hose is suited for both air and water applications, adaptable for use in industries, workshops, and general facilities. Its 25mm internal diameter and lightweight design ensure ease of installation and handling, even across the full 50-meter length. The hose is compatible with common fitting and joining processes, providing flexibility in a variety of operational environments.
