Snug fitting with nipple - female thread, 3/4" F x 20 x 2, PEX

Product detailed description

PEX fittings with nipples are commonly used in residential and commercial heating and plumbing systems. These fittings provide secure connections in radiant floor heating, domestic hot water, and underfloor heating applications. Installers working on new builds or system renovations often use these fittings to connect PEX tubing to threaded components in the system. The fitting is designed for use in environments where the operating temperature does not exceed +120°C.

The fitting is suitable for systems operating at a nominal pressure of PN 10. It is commonly used in conjunction with PEX (cross-linked polyethylene) tubing, which is known for its flexibility and resistance to thermal expansion. The fitting ensures a tight and durable connection in both heating and cold water systems. The internal thread allows for direct connection to standard pipe fittings and valves in the system.

Technical parameters

The nominal pressure rating of PN 10 indicates the fitting is suitable for systems operating at a maximum pressure of 10 bar. This makes it appropriate for low-pressure domestic and heating applications. The nickel-plated brass construction provides corrosion resistance and mechanical strength. The EPDM O-ring ensures a reliable seal and compatibility with PEX tubing.

Installation and connection

To install the fitting, first ensure the PEX tubing is cut cleanly and deburred. Insert the tubing into the fitting until it reaches the stop mark. Use a suitable crimping tool to secure the fitting to the tubing. The internal thread of 3/4 inch allows for direct connection to standard pipe components. It is important to verify that the O-ring is properly seated and that the connection is tightened to the manufacturer's specifications. Common installation mistakes include improper crimping, which can lead to leaks, and using incorrect tools that may damage the fitting or tubing.

Compatibility and accessories

This fitting is specifically designed for use with PEX tubing and is compatible with standard 3/4 inch internal thread components. To complete the installation, additional components such as PEX tubing, crimping tools, and compatible valves may be required. Installers should ensure that all components are from the same system to maintain compatibility and performance.

Technical background for designers

The fitting operates by creating a mechanical and sealed connection between the PEX tubing and the threaded component. The nickel-plated brass body provides resistance to corrosion and ensures long-term durability. The EPDM O-ring provides a flexible and reliable seal that maintains integrity under varying pressure and temperature conditions. The material properties of the brass and EPDM ensure compatibility with both hot and cold water systems. The design of the fitting allows for easy integration into existing systems and ensures minimal disruption during installation.

Service and operation

Routine inspection of the fitting is recommended to ensure the integrity of the connection. Check for signs of wear, corrosion, or leakage. If any issues are detected, the fitting should be replaced immediately. No specific service intervals are provided in the technical documentation, but regular visual inspections are advised to maintain system performance.
