Bravo Technical Service Bulletin: Installing New Construction Fittings in Cold Climates

Bravo LogoInstalling New Construction Fittings in Cold Climates

Bulletin Description

• Proper heat curing of epoxy in cold weather conditions.
• In weather conditions below 50°F, heat will be needed to cure epoxy used for the  installations of Bravo full body fittings and test reducers. However, do not heat the fitting above 150°F. Extremely high temps can damage entry fittings and cause test ports to leak.

Do not use NOV heat blankets directly on full body fittings. These greatly exceed the allowable installation temperature and will damage the fitting bodies as well as the test ports.


  • Recommendation: Sustain heat on the entire interior of sump until full cure cycle has been achieved.
  • Warning: Before applying heat make sure LEL ( Lower Explosive Limit) are measured and are at safe levels.
  • Tip: Use an IR temperature gauge to measure surface temperature of sump and fittings.

1) Pre-heat sump and fitting to a maximum of 150°F.
2) Pre-heat Bravo epoxy to a maximum of 100°F.
3) Apply Bravo epoxy to the fitting per installation guide.
4) Sustain temperature of fitting/adhesive following cure charts.
5) Do not move or adjust sumps or fittings during cure cycle.
6) Make sure the adhesive is fully cured before conducting a testing following epoxy manufacturers’ guidelines.
