**Stainless Steel Press Fitting Pipe System**
The Hopewell press fitting system allows for seamless pipe joining without the need for welding or bolting, making it ideal for a wide range of applications such as cold and hot water supply, heating systems, fire protection, medical gas lines, and industrial petroleum pipelines. It has become a popular alternative to traditional welded fittings in many countries across Europe, Asia, America, and Australia.

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