5.5 Making a Viega PEX Press connection with hand tool
5.5.1 Trimming and inserting the tubing
5.5.2 Pressing with a hand tool
5.5.3 Pressing with a power tool
1.
Square off tubing to proper length. Uneven, jagged or irregular cuts will produce unsatisfactory connections.
2. If using FostaPEX tubing, insert into prep tool, push and turn until no resistance is felt. If using ViegaPEX
Ultra, continue to Step 3.
3. Insert PEX Press tting with attached sleeve into tubing and engage fully.
4. Ensure full tubing insertion at view holes in attached press sleeve. Full insertion means tubing must be
completely visible in at least two view holes and partially visible in the third.
5. Position press tool perpendicular over press sleeve, resting it against the tool locator ring.
Note: The tool locator ring must be in the factory-installed position while making a press to provide a
consistent leakproof PEX press connection. It may be necessary to rotate the tool locator ring to avoid
interference between the ring and tool.
6. Close handles, using trigger to reduce grip span if desired.
7. Extend handle and continue ratcheting until automatic tool release occurs at proper compression force.
8. Warning: The PEX press connection is not leakproof when the tool has been opened by emergency release.
The tool locator ring must be present to ensure a proper PEX Press connection.
5. Insert the appropriate Viega PEX Press jaw into the press tool and push in the holding pin until it locks.
6. Open jaw and position perpendicular over press sleeve, resting it against the tool locator ring.
Note: The tool locator ring must be in the factory-installed position while making a press to provide a
consistent leakproof PEX press connection. It may be necessary to rotate the tool locator ring to avoid
interference between the ring and tool.
7. Start pressing process; hold the trigger until the jaw has automatically released.
8. When press connection is complete, open and remove jaw.
9. Warning: The tool locator ring must be present to ensure a proper PEX Press connection.
