**Stainless Steel Press Fitting Pipe System**
The Hopewell stainless steel press fitting system offers a reliable, non-welded and bolt-free method for joining pipes. It is widely used in cold and hot water supply systems, heating systems, fire protection, medical gas pipelines, and industrial oil and gas applications. This system has become the preferred choice in many European, Asian, and American countries, replacing traditional welded fittings due to its efficiency and durability.

**Note:** Standard pipe length is 6 meters. Custom lengths and specifications are available upon request.
**Sealing Ring Materials:**
- **Option 1: CIIR (Chlorinated Butyl Rubber)** – Suitable for drinking water, tap water, hot and cold water, and sanitary air. Not oil-resistant.
- **Option 2: EPDM (Ethylene-Propylene-Diene Monomer)** – Suitable for drinking water, hot and cold water, sanitary air, and compressed gas. Not oil-resistant.
- **Option 3: FKM (Fluororubber)** – Oil-resistant and sanitary. Ideal for edible oil and compressed air. Slightly more expensive than CIIR, EPDM, and NBR.
