Seamless Concealed Fire Sprinkler Heads For Clean Room Ceilings
✔️ Solid brass frame holds 68 C glass bulb and half inch fitting

This two pack concealed pendent sprinkler kit pairs a 15 mm zero point five inch threaded head with a matching silver flush cover plate. Each unit sits neatly inside drop ceilings or drywall voids and stays hidden until an emergency requires instant water coverage across offices, retail spaces, or small commercial rooms.

✅ 15 mm zero point five inch connection size fits most wet pipe layouts ✅ Sixty eight Celsius activation rating protects rooms from rapid heat spread ✅ Copper alloy deflector spreads spray evenly without cold spots ✅ Handy replacement design saves time during retrofits or new builds

💡 How does a thermal response sprinkler head activate inside suspended ceilings.
- A sixty-eight degree glass bulb expands and shatters when ambient heat spikes above normal operating ranges.
- The shattered bulb opens the internal valve so pressurized water flows through the copper deflector immediately.
- A standard half inch supply line keeps flow steady during active suppression runs across commercial spaces.
- The flush cover drops away instantly once thermal activation occurs without manual intervention needed
