When to Use
Install or rebuild with UCADPTR whenever the existing connecting nut or adapter shows wear, leaks, cracks, or chemical damage. It’s commonly used during regular maintenance, pump servicing, or when resizing tubing for chemical dosing lines.
Installation & Maintenance Tips
- Turn off and depressurize the chemical-feed system before replacing the nut/adapter.
- Remove the old fitting, clean the tubing ends, then thread the new UCADPTR nut onto the pump head or fitting. Ensure the 1/4″ adapter is seated properly before inserting tubing.
- Hand-tighten the nut firmly — avoid overtightening plastic components to prevent cracking.
- Inspect periodically for stress, cracking, or leaks; replace immediately if any sign of chemical-induced degradation appears.
- Keep spare nuts and adapters on hand — many pool-service calls stem from worn or leaky chemical feed fittings.
