About this item

  • Purpose: IWS-1960 expander tool is designed for expanding type A PEX pipe for insertion of ASTM F1960 expansion-style fittings.
  • Components: IWS-1960 F1960 Hand Expander Tool Kit includes 1/2", 3/4" and 1" heads, tool lubricant and a sturdy carrying case.
  • Versatility: Provides consistent and reliable expansion of PEX-a tubings and expansion sleeves from Uponor(Wirsbo) ProPex, Sioux Chief PowerPex, Everflow PexFlow, Apollo ExpansionPex, etc,.
  • Secure Connection: Once the fitting is inserted into the expanded ring and pipe combination, the elastomeric properties of this PEX combination bring the expanded material back around the fitting to make a sealed, permanent and visually inspectable connection.
  • Applications: Plumbing, fire safety, radiant heating and cooling systems. Ideal for residential, commercial and industrial projects.



The F1960 cold expansion fitting system consists of ASTM F1960 cold expansion fittings (F1960 fittings) in polymer and lead-free brass, and PEX reinforcing rings (PEX rings), for use with PEXa shield pipe for potable plumbing system applications and barrier pipe for hydronic radiant heating and cooling system applications. The F1960 fitting system is intended for use in hot- and cold-water potable systems and hydronic heating and cooling systems.

Quick Guide

1. Square cut the PEX tubing perpendicular to the length of the tubing.

2. Slide the ProPEX Ring over the end of the tubing until it reaches the stop edge.

3. Fully expand tubing for several times and rotate tubing during each expansion.

Cold-weather Expansions

Temperatures affect the time required for the tubing and ring to shrink onto the fitting. The colder the temperature, the slower the contraction time.
