This bundle of eight fire sprinkler heads provides solid backup for residential garages, hobby shops, and machine rooms. Each unit comes with a polished chrome plated brass shell that fights off moisture and rust. They are built to snap straight onto domestic plumbing lines without fancy tools. The thermal element pops at 155 F to dump water right where it matters, and the steady 1.2 MPa rating keeps the flow smooth during activation.

✅ Thermal trigger fires at a precise 68 C for instant coverage
✅ Polished brass exterior stays bright and avoids corrosion spots
✅ Internal K115 pattern throws even distribution across wide areas
✅ Direct threading saves labor on tight ceiling joists

💡 What is a fire sprinkler head used for in a dry commercial building?

Besides being the final release point that pumps water directly onto ignition sources, these handy discharge units keep spaces protected. Getting the setup right matters most.
- Match a high temp rating like 155 F for chop shops prone to sparks
- Lock in the 3/4 In (19 mm) connection to your mainline to stop leaks dead
- Rely on the K115 flow coefficient to push liquid fast before damage spreads
