Best Practices For Secure Push-Fit Installation

Minor preparation ensures fittings work like pro-grade joints. IPS recommends a couple of habits that cut leaks and callbacks. Follow simple habits to maintain reliability for every job.

Square Cuts, Full Insertion, And Clips

Make a square cut and deburr the end for a good seal. A bad cut can nick seals and lead to dripping.

Mark the insertion depth and push until the tube seats fully. Check by tugging, then add a lock clip on important connections for extra security.

When To Choose Twist-And-Lock Or Superseal

Choose twist-and-lock where vibration or movement is expected. It increases grip while keeping it fast.

Use Superseal for extra sealing in critical areas. Use tube supports on PEX or hot lines to keep sealing pressure steady.

“Cut square, seat fully, and use clips—these steps save time and service calls.”

  • Avoid side-loads and clamp long runs to lower strain on pipe and fittings.
  • Keep parts clean; dirt ruins seals and increases leaks.
  • Check the specs and view rated temperature and pressure before use.
  • Carry spare clips and release tools for quick field adjustments.
