Why is my Rainbow Q-Connect bottle hissing when pressurized?
- D
  David FowlerAug 15, 2025
  A hissing or leaking sound when the bottle is pressurized may be due to several reasons. The bottle top may not be securely threaded onto the bottle; in this case, remove and re-attach the bottle top assembly. There might be an improper seal between the bike pump and the Schrader valve; re-attach the bike pump securely. The duckbill valve could be damaged or worn, requiring cleaning, replacement, or plugging with a rubber valve plug. A leaking Schrader valve may also be the cause; try cleaning or replacing the valve stem.

  If the bottle cannot be pressurized or does not hold pressure, it may be due to an improper seal between the bike pump and Schrader valve; re-attach the bike pump securely. A faulty or damaged bike pump could also be the cause, requiring replacement. Alternatively, the Schrader valve may be faulty or damaged, needing repair or replacement. Ensure the harness tubing is connected to the bottle cap, as the main bottle valve may be open with the tubing disconnected.

What to do if one injection tip of my Rainbow Industrial Equipment will not inject?
- H
  Haley JacksonAug 22, 2025
  If one injection tip will not inject, first try a new injection site. The injection tip or handle may be plugged, so clean the injection tee components. Also, ensure that all injection tees are securely inserted into their injection sites and that no tees are leaking, as a pressure leak somewhere in the lines could be the cause.

Why is the black push-to-connect tee leaking on my Rainbow Q-Connect Industrial Equipment?
- C
  Courtney EdwardsAug 26, 2025
  If the black push-to-connect tee is leaking, it might be because the tubing is only partially inserted; push the tubing in farther. The tubing may have been scored too deeply; restore the end or replace the tubing segment. The tubing may have been cut incorrectly; re-cut the end to ensure a straight edge, or replace the tubing segment. A damaged push-to-connect fitting could also be the cause, so replace the push-to-connect tee.

How to fix Rainbow Industrial Equipment when tubing cannot be inserted into push-to-connect fitting?
- E
  Erin CastilloAug 28, 2025
  If tubing cannot be inserted into the push-to-connect fitting, inspect the fitting for obstructions, such as a broken tubing end. Hardened product residue may also be preventing the push-to-connect function; soak the fitting or tee in a cleaning solution to loosen the residue.

What to do if product pools in tubing during injection application with Rainbow Industrial Equipment?
- T
  Todd CallahanSep 1, 2025
  If product pools in the tubing during injection application, raise the tubing with pooled product above the level of the surrounding tubing to allow the product to be gravity-fed into the nearest injection port. Alternatively, the harness connector may be malfunctioning or worn out; replace it, or bypass it with a black push-to-connect tee.

  If the tip spins in the handle and can't be tightened, the handle threads may be stripped; replace the injection tee handle. Alternatively, the set screw may not be properly tightened; remove the set screw and injection tip, then replace and tighten the tip and set screw.

Why is the harness connector of my Rainbow Q-Connect Industrial Equipment not snapping together?

  If the harness connector will not snap together, it is likely due to dirt or residue build-up. Thoroughly clean the harness connectors.

What to do if injection tee is difficult to remove from injection site of Rainbow Q-Connect?
- K
  Kathy CunninghamSep 12, 2025
  If the injection tee is difficult to remove from the injection site, it may be due to an extremely tight seal between the injection site and the tip. Turn the injection tee handle clockwise while smoothly pulling backward on the handle. Lightly rock or jiggle the tee handle side-to-side to break the seal; do not twist, as twisting back and forth may break the tip or strip the handle threads.
