The NeoFit Acetal Tube End Stop is a practical and dependable component designed to cap outer diameter (OD) tubing in a wide range of fluid and gas applications. Manufactured from acetal, a durable engineering plastic, and equipped with a food-grade EPDM O-ring, this fitting ensures a secure seal for potable water, pure water, air, and inert gases. Its compatibility with both plastic and copper OD tubing makes it a versatile option for use in plumbing, HVAC systems, beverage lines, and other industrial applications. The push-fit design allows for easy installation and removal while maintaining a tight, leak-resistant connection. The combination of the acetal body and EPDM seal provides resistance to wear, moisture, and pressure variations, supporting long-term performance and reliability. Whether used to terminate tubing temporarily or permanently, this tube end stop offers a clean and efficient way to close off unused or inactive lines. Its durable construction and compatibility with common tubing sizes make it a practical solution for system maintenance, safety, or fluid control tasks across multiple industries.
