high quality flexible corrugated rubber hoses ,welcome customize OEM design

NBR/PVC thermal insulation rubber hose for HVAC&R

Characteristics of our rubber hose:

1. Closed-cell Structure.

2. Low Heating Conductivity.

3. Low Water Absorption Rate.

4. Good Fireproof and Soundproof Performance.

5. Good Aging Resistance Performance.

6. Simple and Easy Installation.

Application:

Rubber hose is used to retard heat transmission and control condensation from chilled-water and refrigeration systems. It also efficiently reduces heat transfer for hot-water plumbing and liquid-heating and dual-temperature piping

Rubber hose is ideal for applications in:

Ductwork

Dual temperature and low pressure steam lines

Process piping

Air-conditioner, including hot gas piping
