ProLine Series Stiffeners offer a way to ensure a water-tight seal for Brass Push Fittings that will connec to PEX tubing. These inserts provide pressure to the fitting connection mechanisms allowing for a secure and water-tight seal. These stiffeners can be added or removed when necessary and are not necessary for copper or CPVC tubing.

  • Pex tubing is too flexible to engage fitting locking mechanisms
  • Stiffeners provide interal wall support to engage locking mechanisms
  • Simply insert the stiffener before inserting the tubing
  • Stiffeners are only necessary when connecting to PEX tubing
  • Materials are safe for potable water applications
  • Stiffeners are sold seperately from fittings
