1/2 inch Carbon Steel Water Press Cap

Streamline 1/2" Carbon Steel Press Cap – For System Isolation and Termination

The 1/2" Carbon Steel Water Press Cap by Streamline is designed to permanently or temporarily terminate pressurized carbon steel piping systems. Used in conjunction with standard press-fit technology, this component supports clean system isolation during testing, flushing, or line capping in both new and retrofit applications.

This cap is manufactured from corrosion-resistant carbon steel and meets the technical and mechanical demands of commercial and industrial plumbing environments. Engineered to comply with performance standards for press connection systems, it ensures a secure seal that eliminates the need for threading or welding.

Key Features and Benefits

• ✅ Press Connection – Designed for compatibility with standard press-fit tools and jaws (e.g., TH, V profiles).
• ✅ Material Integrity – Manufactured from carbon steel with zinc-plated or corrosion-inhibiting coating where applicable.
• ✅ Pressure and Temperature Rated – Suitable for systems up to 200 PSI and 250°F depending on application and sealing element used.
• ✅ EPDM Sealing Element – Factory-installed O-ring ensures leak-tight performance under dynamic pressure conditions.
• ✅ Application Versatility – Supports termination of closed-loop HVAC, potable water, and industrial utility piping systems.
