• PEX Crimp System: Designed for use with PEX crimp rings and compatible crimp tools (sold separately). Not compatible with cold-expansion systems.

• Certified and Safe: NSF certified, compliant with ASTM F1807/F2159 standards, UPC, IPC, and cUPC approved.

• Temperature and Pressure Ratings: Rated for up to 200°F and 200 PSI, suitable for hot and cold water applications.

• Package Includes: 1 elbow fitting; PEX crimp rings and tools sold separately.

Tips & Tricks – Step-by-Step Installation:

Step 1: Prepare the Copper Pipe

• Cut the copper pipe squarely and remove burrs with a deburring tool.

• Clean the outside of the copper pipe and the inside of the female elbow fitting using a wire brush or emery cloth.

Step 2: Apply Flux

• Apply a thin layer of lead-free flux to both the copper pipe and the fitting to ensure proper solder flow and prevent oxidation.

Step 3: Solder the Copper Connection

• Heat the elbow fitting evenly with a propane torch until the flux bubbles.

• Touch lead-free solder to the joint; allow it to flow via capillary action for a secure, leak-proof seal.

• Allow the joint to cool naturally before proceeding.

Step 4: Prepare the PEX-B Pipe

• Slide a PEX crimp ring over the end of the PEX-B pipe.

• Fully insert the PEX-B pipe onto the fitting barb.

Step 5: Crimp the PEX Connection

• Use a compatible PEX crimp tool to secure the ring, ensuring a tight, leak-free seal.

• Verify the crimp with a go/no-go gauge if available.

Applications:
Ideal for potable water distribution, hydronic heating systems, and any plumbing project requiring a secure 90-degree transition from 1/2 in. PEX-B to 3/4 in. copper pipe.
