Product Overview

Compression fittings are designed to beused with RadiantPEX-AL in radiant heatingand snowmelting applications. The fittingsare compatible with water and water/glycol solutions. No other tubing type may be used.

Fittings are available in a variety ofCompression x Sweat, Compression x NPTor Compression x BSP connections.

Warnings:• When using sweat fittings, ensure

that all O-rings and insulatorinserts are removed prior to soldering.

• If connections must be made intemperatures lower than 30°F(0°C), caution must be taken to allow for a proper seal.

Connection Steps

Step 1:Cut a clean, square end to the tubing.

Step 2:Use the Reamer tool to shape and prep the tubing.

Step 3:Slide the compression nut over the tubing.

Step 4:Slide the compression ring over the tubing.

Step 5:Make sure the plastic insulator insert is in place at the base of the fitting.

Step 6:Slide the tubing over the fitting. Make sure

the tubing is sealed against the insulator insertof the fitting.

Step 7:Slide the compression nut up and beginthreading it onto the base. The compressionring will automatically be positioned overthe fitting.

Step 8:Use a box-end wrench to complete the connection (Do not use a crescent wrench). Tighten the connection until snug and then an additional 1/4 turn.
