Choose the Correct Fit
Match this 1" jaw to the crimp ring and PEX fitting. Milwaukee lists F1807 & F2159 compatibility; follow the fitting maker’s sizing instructions.
Use the M18 Short Throw press tool family. Do not substitute a PureFlow press sleeve or ProPEX expansion connection for a crimp-ring assembly.
Installation & Care
Remove the battery before changing jaws and secure the retaining pin. Check the jaw for cracks, damage or debris before making a connection.
Position the crimp ring as the fitting maker directs. Keep the jaw square, complete the tool cycle and check the finished crimp as instructed.

Important Product Questions
Which press tool is required?
Use this jaw with the M18 Short Throw tool family. Verified models are 2674-20. Short-throw and FORCE LOGIC jaws are distinct accessory families.
Is this an expansion head or a PureFlow jaw?
No. It is a 1" PEX crimp jaw for F1807 & F2159 connections. Expansion fittings and PureFlow sleeves need the matching system-specific accessories.
How does the spring-loaded opening help?
It grips the crimp ring to help maintain alignment. It does not replace correct ring position, a complete press cycle or the fitting maker’s inspection procedure.
